BTM7741G data sheet 8 rev. 1.0, 2007-05-21 4 circuit description 4.1 input circuit the control inputs ih1,2 consist of ttl /cmos compatible schmitt- triggers with hysteresis. buffer amplifiers are driven by these stages and convert the logic signal into the necessary form for driving the power output stages. the inputs are protected by esd clamp-diodes. the inputs il1 and il2 are connected to the internal gate-driving units of the n-channel vertical power-mos-fets. 4.2 output stages the output stages consist of an low r dson power-mos h-bridge. in h-bridge configuration, the d-mos body diodes can be used for freewheeling when communicating inductive loads. if the high -side switches are used as single switches, positive and negative voltage spikes which occur when driv ing inductive loads are limited by integrated power clamp diodes. 4.3 short circuit protection the outputs are protected against ? output short circuit to ground ? output short circuit to the supply voltage, and ? overload (load short circuit). an internal op-amp controls the drain-source-volt age by comparing the ds-voltage-drop with an internal reference voltage. above this trip point the op-amp reduces the output current depending on the junction temperature and the drop voltage. 4.4 overtemperature protection the high-side and the low-side switches also incorporat e an over temperature protec tion circuit with hysteresis which switches off the output transistors. in the case of the high-side switches, the status output is set to low. 4.5 undervoltage lockout when v s reaches the switch-on voltage v uvon the ic becomes active with a hysteresis. the high-side output transistors are switched off if the supply voltage v s drops below the switch off value v uvoff . 4.6 open load detection the open load detection of the BTM7741G works in off co ndition and is based on a voltage measurement at the source of the high side switch. in order to use the open load detection sh2 has to be connected to vcc via a pull up resistor. because this pull up resistor would connec t the bridge output to the c supply it needs to be disconnected whenever the high side swit ch is on. this can be done by a transistor as shown in the application example ( figure 4 ?application example BTM7741G? on page 15 ). to check for open load: ? set ih1 = ih2 = low (both high side switches off) ? set il2 = low, il1 = high (only low side switch 1 is on) ? connect rol (open load pull up) to 5v via transistor if the load is connecte d properly it will pull down the volta ge at sh2 to a value close to 0v. if the load is disconnected the resistor will pull the voltage at sh2 to value close to vcc. if the voltage at sh2 is higher than the open load detection voltage v out(ol) then st will be pulled down.
data sheet 9 rev. 1.0, 2007-05-21 BTM7741G 4.7 status flag the status flag output is an open drain output with zener-diode which requires a pull-up resistor, as shown in the application circuit in figure 4 ?application example BTM7741G? on page 15 . various errors as listed in the table ?diagnosis? are reported by switch ing the open drain output st to low. table 3 truth table and diagnosis (va lid only for the high-side-switches) flag ih1 ih2 sh1 sh2 st remarks inputs outputs normal operation; identical with functional truth table 0 0 1 1 0 1 0 1 l l h h l h l h 1 1 1 1 stand-by mode switch2 active switch1 active both switches active open load at high-side switch 1 open load at high-side switch 2 0 1 x x x x 0 1 z h x x x x z h 0 1 0 1 detected detected overtemperature high-side switch1 0 1 x x l l x x 1 0 detected overtemperature high-side switch2 x x 0 1 x x l l 1 0 detected overtemperature both high-side switches 0 x 1 0 1 x l l l l l l 1 0 0 detected detected under voltage x x l l 1 not detected inputs: outputs: status: 0 = logic low z = output in tr istate condition 1 = no error 1 = logic high l = output in sink condition 0 = error x = don?t care h = output in source condition x = voltage level undefined
