L9952GXP description doc id 13518 rev 5 11/68 2 description 2.1 voltage regulator the L9952GXP contains 2 independent and fully protected low drop voltage regulators, which are designed for very fast transient response. the output voltage is stab le with loads capacitors > 220nf. 2.1.1 voltage regulator: v1 the voltage regulator v1 provides 5v supply voltage and up to 250ma continuous load current for the external digital logic (micro controller, can transceiver ...). in addition the regulator v1 drives the L9952GXP internal 5v loads. the voltage regulator is protected against overload and over-temperature. an external reverse current protection has to be provided by the application circuitry to prevent the output capacitor from being discharged by negative transients or low input voltage. the output voltage precision is better than +/-2% (incl. temperature drift and line-/load regulation) for operating mode; respectively +/-3% during low current mode. current limitation of the regulator ensures fast charge of external bypass capacitors. the output voltage is stable for ceramic load capacitors > 220nf. if device temperature exceeds tsd1 threshol d, all outputs (hsx, lsx, v2, lin) will be deactivated except v1. hence the micro controlle r has the possibility for interaction or error logging. in case of e xceeding tsd2 threshold (tsd2>tsd1), also v1 will be deactivated (see state chart fig. 3.1: ?protection and diagnosis?). a timer is started and the voltage regulator is deactivated for t tsd = 1sec. during this time, all other wakeup sources (can, lin, and wu1...4) are disabl ed. after 1 sec, th e voltage regulator will try to restart automatically. if tsd2 occurs within one minute and for 8 consecutive times, the L9952GXP enters the v bat - standby mode. in case of short to gnd at ?v1? after initial turn on (v1 < 2v for at least 4ms) the L9952GXP enters the v bat - standby mode. reactivation (wake-up) of the device can be achieved with signals from can, lin, wu1..4, spi. 2.1.2 voltage regulator: v2 the voltage regulator v2 supplies additional 5v loads (e.g. logic components, external sensors, external potentiometers). the continuous load current is 50ma. the regulator provides accuracy better than + 3% @ 50ma (4% @ 100ma) load current. in case of short to gnd at ?v2? after initial turn on (v2 < 2v for at least 4ms) the v2 regulator is switched off. micro processor has to send a clear command to reactivate the v2 regulator. v2 is protected against: overload over temperature short circuit (short to ground and battery supply voltage) reverse biasing
description L9952GXP 12/68 doc id 13518 rev 5 2.2 power control in operating modes the L9952GXP can be operated in 4 different operating modes: active flash v 1 - standby v bat - standby a cyclic monitoring of wake-up inpu ts is available in stand-by modes. 2.2.1 active mode all functions are available. 2.2.2 flash mode to disable the watchdog feature a flash program mode is available. the mode can be entered by v pwm2 9v in this case all other functions are the same as in active mode watchdog can be disabled as well as soon as L9952GXP enters the v1 standby mode (see section 2.9 for details) note: ?high? level for flash mode selection is v pwm2 9v. for all other operation modes, standard 5v logic signals are required. for proper operation pwm 1 must not be set to a voltage level above standard 5v logic. 2.2.3 v 1 standby mode outputs and internal loads are switched off. to supply the micro controller in a low power mode, the voltage regulator1 (v1) remains active. the intention of the v1 standby mode is to preserve the ram contents. a cyclic contact supply and wake-up input sense feature (for cyclic monitoring of external contacts) can be activated by spi. 2.2.4 v bat standby mode to achieve minimum current consumption during v bat standby mode, all L9952GXP functions (except the ones for wake up functionality) are switched off. in v bat - standby mode the current consumption of the L9952GXP is reduced to 7a, typical (without cyclic sense feature selected). the transitions from active mode to either v 1 -standby or v bat - standby are controlled by spi. v bat - standby mode is dominant; i.e. if both bits, v 1 - standby and v bat - standby are set to ?1?, the l9952g xp will enter v bat - standby mode.
L9952GXP description doc id 13518 rev 5 13/68 2.3 wake up events a wake-up from standby mode will switch the devi ce to active mode. this can be initiated by one or more of the following sources: change of the lin state at lin bus interfaces a current at the inh pin (i 200ua) controlled by the can-transceiver (the can transceiver is not a part of the ic). positive/negative edge at wake up pins wu1...wu4 -> change of level after going into stand-by change of open-load state at out1 to 4 spi access in v1-standby mode (csn is low and first rising edge on clk) all wake-up events (except wake-up by lin, inh or spi from v1standby mode) generate a reset pulse (nreset low for 2ms). wake-up events from v1standby by lin, inh or spi do not cause a reset and the reset generation is blocked for 2ms, i. e. a watchd og failure during this timeframe will not cause a reset. table 3. wake up events wake up source description lin always active inh always active wu1...4 can be individually disabled via spi open load at hs outputs can be individually disabled via spi spi access always active (except in v bat - standby mode) high level at pwm2 input vpwm2 > 9v (1) 1. only if internal oscillator is running (e. g. in cyclic sense confi guration or after wake-up request).

description L9952GXP 16/68 doc id 13518 rev 5 2.5 wake up inputs the de-bounced digital inputs wu1...wu4 can be used to wake up the L9952GXP from standby modes. these inputs are sensitive to any level transition (positive and negative edge) for static contact monitoring, a filter time of 64 s is implemented at wu1-4. the filter is started when the input voltage passes the specified threshold. at vin > 1v and vin < (vs ? 2v), a wake-up request is processed. during wake-up request, the in ternal oscillator and other circuit blocks are activated in order to allow more accurate monitoring of the inputs. in addition to the continuous sensing (static contact monitoring) at the wake up inputs, a cyclic wake up feature is implemented. this feature allows periodical activation of the wake- up inputs to read the status of the external contacts. the periodical activation can be linked to timer 1 (0.5sec to 4.0sec in 0.5sec steps) or timer 2 (50ms). the input signal is filtered with a filter time of 16us after a programmab le delay (80us or 800us). a wake-up will be processed if the status has changed versus the previous cycle. the outputs out_hs and out1-4 can be used to supply the external contacts with the timing according to the cyclic monitoring of the wake-up inputs. if the wake-up inputs are configured for cyclic sense mode (icxx in control register 2), the same input filter timing (timer1 or timer2) and the corresponding input filter delay (control register 2) must be used for the hs outputs (hsxx in control register 0) which supply the external contact switches. in standby mode, the inputs wu1-4 are spi configurable for pull-up or pull-down current source configuration according to the setup of the external contacts (pull-up for active low contacts, pull-down for active high contacts). in active mode the inputs have a pull down resistor of 100 kohm (typ). in active mode, the input status can be read by spi (status register 0). static sense should be configured (control register 2) before the read operation is started (in cyclic sense configuration, the input status is updated acco rding to the cyclic sense timing; therefore, reading the input status in this mode may not reflect the actual status). 2.6 hall sensor ports: wu3,4, dig_out 3,4 applications like hall sensor outputs need high processing speed. the 12v signals connected to the wakeup inputs wu3 and wu4 can be looped through to the digital outputs dig_out 3 and dig_out 4 (5v) in order to avoid read out of the input state by spi. the setup is programmable by spi. the open load states of the high side drivers out1 and out2 can be looped through the digital outputs dig_out3 and dig_out4 without delay. in addition, the status of out1 and out2 can be accessed through the spi interface. this feature is intended for 2-pin hall sensors. open load information is only valid during on state. the open load threshold at pins out1...4 can be switched from i old1 = 2ma to i old2 = 8 ma via spi .
L9952GXP description doc id 13518 rev 5 17/68 2.7 interrupt dig_out4 can be configured via spi as interrupt output (int) by setting bit 20 / cr1:int_enable=?1?. this configuration will enab le the following behaviour: int pin is pulled high for 2ms in case of any wake-up from v1 standby mode (wu inputs, lin, inh, spi, open load hs, iv1 > i cmp _ris) wake-up events from v1 standby do not generate a reset (i.e. nreset is not pulled low) the dig_out4 settings in cr1 (bits 12..14) will be ignored 2.8 cyclic contact supply in v1 and v bat - standby mode, any high side driver output (out1..4, ouths) can be used to periodically supply external contacts. the timing is selectable by spi timer 1: period is x sec, the on-time is 10ms resp. 20ms with x {0.5, 1.0, 1.5, ... 4 } timer 2: period is 50ms, the on- time is 100us resp. 1ms: note: cyclic sense setup : if cyclic sense feature is used for wake-up inputs (icxx in control register 2), same input filter timing (t imer1 or timer2) must be used for hs outputs (hsxx in control register 0). 2.9 window ? watchdog during normal operation the watchdog monitors the micro controller within a nominal trigger cycle of 10ms. in v bat -standby , v1-standby and flash program modes, the watchdog circuit is automatically disabled. however, the watch dog will remain enabled in v1-standby mode until the current at v1 decreases below i cmp _fall. the v1 current monitoring can be disabled, if the i cmp bit (cr2, d20) is set to '1'. after ?power-on?, ?standby mode? or reset, the window watchdog starts with a long open window (65ms). the long open window allows the micro controller to run its own setup and then to trigger the watchdog via the spi. the trigger is finally accepted when the csn input becomes high after the transmission of the spi word. a correct watchdog trigger will start the window watchdog with a closed window (< 6ms) followed by an open window (< 10ms), see timing diagrams. subsequently, the micro controller has to serve the watchdog by alternating the watchdog trigger bit (cr0, d19). the ?negative? or ?positive? edge has to meet the open window time. a correct watchdog trigger signal will immediately start the next closed window. after 8 watchdog failures in sequence, the v1 regulator is switched off for 200ms. in case of 7 further watchdog failures, the v1 regulator is completely turned off and the device goes into v bat - standby mode until a wakeup occurs. (e.g. via lin, can/inh).
description L9952GXP 18/68 doc id 13518 rev 5 the watchdog is triggered by toggling the trigger bit (cr0, d19). note: the active trigger window will be reset after each correct trig ger write operation. in case of reset (nreset low for 2ms) the trigger bit is set to ?0?. in case of a wd failure, the outputs (lsx, hsx, v2) are switched off and nreset is pulled low for 2ms. writing to control register 0 without inverting the wd trigger bit is possible at any time. figure 4. watchdog watchdog active with normal window (10ms) hsd, lsd : according to cr0 reset (nreset =low for 2ms) lsd: off (control bits set to ? 0') hsd: off (control bits remain unchanged ) watchdog active with ?long open window?

L9952GXP description doc id 13518 rev 5 23/68 2.19 linpu the linpu (lin pull up) signal is set by L9952GXP logic in order to drive the lin transceiver in master mode. the master mode is realized by an internal high side switch and an external diode in series with an external 1k resistor. in master mode the high side switch is closed causing an external pull up path in parallel to the internal one (diode & 30k resistor). hs (high side) characteristics: hs does not have an over current protection. the hs remains active in standby mode. switch off only in case of over temperature (tsd2 = thermal shutdown #2). typical r dson , 10 . the linpu is activated by default (lin master mode) and can be switched off with a spi command (see register 2) to reduce current in case of lin shorted to ground. 2.20 serial peripheral interface (spi) a 24 bit spi command (2 adresses + 22 data bits) is used for bi-directional communication with the micro controller. during active mode, the spi: 1) triggers the watchdog 2) controls the modes and status of all L9952GXP modules (incl. input and output drivers) 3) provides driver output diagnostic 4) provide l9952 diagnostic (incl. over temperature warning, L9952GXP operation status) note: during stand-by modes, the spi is generally deactivated. the spi can be driven by a micro controller with its spi peripheral running in following mode: cpol=0 and cpha=0. for this mode input data is sampled by the low to high transition of the clock clk, and output data is changed from the high to low transition of clk. this device is not limited to micro cont roller with a build-in spi. only three cmos- compatible output pins and one input pin will be needed to communicate with the device. a fault condition can be detected by setting csn to low. if csn = 0, the do-pin will reflect the global error flag (fault condition) of the device which is a logical -?or? of all over current, vs- over / under voltage, temperature warning/shutdown and v1 fail bits. the micro controller can poll the status of the device without the need of a full spi-communication cycle. 2.20.1 chip select not (csn) the input pin is used to select the serial interface of this device. when csn is high, the output pin (do) will be in high impedance state. a low signal activates the output driver and a serial communication can be started. the state during csn = 0 is called a communication frame.
description L9952GXP 24/68 doc id 13518 rev 5 2.20.2 serial data in (di) the input pin is used to transfer data serial in to the device. the data applied to the di will be sampled at the rising edge of the clk signal and shifted into an internal 24 bit shift register. at the rising edge of the csn si gnal the contents of the shift register will be transferred to data input register. the writing to the selected data input register is only enabled if exactly 24 bits are transmitted within one communication frame (i.e. csn low). if more or less clock pulses are counted within one frame the complete frame will be ignored. this safety function is implemented to avoid an activation of the output stages by a wrong communication frame. note: due to this safety functionality a daisy chai ning of spi is not possible. instead, a parallel operation of the spi bus by controlling th e csn signal of the connected ic's is recommended. 2.20.3 serial data out (do) the data output driver is activated by a logi cal low level at the csn input and will go from high impedance to a low or high level depending on the global error flag (fault condition). the first rising edge of the clk input after a high to low transition of the csn pin will transfer the content of the selected status register into the data out shift register. each subsequent falling edge of the clk will shift the next bit out. 2.20.4 serial clock (clk) the clk input is used to synchronize the input and output serial bit streams. the data input (di) is sampled at the rising e dge of the clk and the data ou tput (do) will ch ange with the falling edge of the clk signal. the spi can be driven with a clk frequency up to 1mhz. 2.20.5 data registers the device has 3 control registers and 2 status registers. the first two bits (d22+d23) at the di-input are used to select one of the control registers. all bits are first shifted into an input shift register. after the rising edge of csn the contents of the input shift register will be written to the selected control register only if a frame of exact 24 bits is detected. if the control register 1 is selected fo r data transfer, the status regi ster 1 will be transferred to the do during the current communication frame. for the selection of control register 0 or control register 2, the status register 0 is transferred to do.
