External Parts
Typical external parts are shown in the following table.
Part C1, C2, C3 R1 C4 R2 C5 C6 R3 Typical 25 V/2.2 F 0.62 1 % (1 W) 25 V/1000 pF 5 % 27 k 5 % 25 V/10 F 25 V/0.1 F 5.1 k Purpose Bootstrap capacitor Current detection PWM frequency setup PWM frequency setup Control power supply stability VREG power supply stability FG pin pull-up resistor Remarks (Note 1) (Note 2) (Note 3) (Note 3) (Note 4) (Note 4) (Note 5)
Note 1: The required bootstrap capacitance value varies according to the motor drive conditions. Although the IC can operate at above the VBS undervoltage level, it is however recommended that the capacitor voltage be greater than or equal to 13.5 V to keep the power dissipation small. The capacitor is biased by VCC and must be sufficiently derated accordingly. Note 2: The following formula shows the detection current: IO = VR / R1 (VR = 0.5 V typ.) Do not exceed a detection current of 1 A when using the IC. Note 3: With the combination of C4 and R2 shown in the table, the PWM frequency is around 20 kHz. The IC intrinsic error factor is around 10 %. The PWM frequency is broadly expressed by the following formula. (In this case, the stray capacitance of the printed circuit board needs to be considered.) fc = 0.65 / { C4 x (R2 + 4.25 k)} [Hz] R2 creates the reference current of the PWM triangular wave charge/discharge circuit. If R2 is set too small it exceeds the current capacity of the IC internal circuits and the triangular wave distorts. Set R2 to at least 9 k. Note 4: When using the IC, adjustment is required in accordance with the use environment. When mounting, place as close to the base of the IC leads as possible to improve noise elimination. Note 5: The FG pin is open drain. If the FG pin is not used, connect to the GND. Note 6: If noise is detected on the Input signal pin, add a capacitor between inputs. Note 7: A Hall device should use an indium antimony system.
Handling precautions
When switching the power supply to the circuit on/off, ensure that VS < VVSOFF (all IGBT outputs off). At that time, either the VCC or the VBB can be turned on/off first. Note that if the power supply is switched off as described above, the IC may be destroyed if the current regeneration route to the VBB power supply is blocked when the VBB line is disconnected by a relay or similar while the motor is still running. (2) The IC has a forward/reverse rotation control pin (FR). To change the rotation direction, switch the FR pin after the motor is stopped in the state that the VS voltage is lower than or equal to 1.1 V. When the FR pin is switched while the motor is rotating, the following malfunctions may occur. A shoot-through current may flow between the upper arm and lower arm in the output stage (IGBT) at that moment when the motor is switched. An over current may flow into the area where the over current protection circuit cannot detect it. (3) The triangular wave oscillator circuit, with externally connected C4 and R2, charges and discharges minute amounts of current. Therefore, subjecting the IC to noise when mounting it on the board may distort the triangular wave or cause malfunction. To avoid this, attach external parts to the base of the IC leads or isolate them from any tracks or wiring which carries large current. (4) The PWM of this IC is controlled by the on/off state of the high-side IGBT. (5) If a motor is locked where VBB voltage is low and duty is 100 %, it may not be possible to reboot after the load is released as a result of the high side being ON immediately prior to the motor being locked. This is because, over time, the bootstrap voltage falls, the high-side voltage decrease protection operates and the high-side output becomes OFF. In this case, since the level shift pulse necessary to turn the high side ON cannot be generated, reboot is not possible. A level shift pulse is generated by either the edge of a Hall sensor output or the edge of an internal PWM signal, but neither edge is available due to the motor lock and duty 100 % command. In order to reboot after a lock, the high-side (1)

2008-08-13
TPD4122K
power voltage must return to a level 0.5 V (typ.) higher than the voltage decrease protection level, and a high-side input signal must be introduced. As a high-side input signal is created by the aforementioned level shift pulse, it is possible to reboot by reducing PWM duty to less than 100 % or by forcing the motor to turn externally and creating an edge at a Hall sensor output. In order to ensure reboot after a system lock, the motor specification must be such that maximum duty is less than 100 %.
Description of Protection Function
(1) Over-current protection The IC incorporates an over-current protection circuit to protect itself against over current at startup or when a motor is locked. This protection function detects voltage generated in the current-detection resistor connected to the RS pin. When this voltage exceeds VR (= 0.5 V typ.), the high-side IGBT output, which is on, temporarily shuts down after a mask period, preventing any additional current from flowing to the IC. The next PWM ON signal releases the shutdown state.

Under-voltage protection The IC incorporates under-voltage protection circuits to prevent the IGBT from operating in unsaturated mode when the VCC voltage or the VBS voltage drops. When the VCC power supply falls to the IC internal setting VCCUVD (= 11 V typ.), all IGBT outputs shut down regardless of the input. This protection function has hysteresis. When the VCC power supply reaches 0.5 V higher than the shutdown voltage (VCCUVR (= 11.5 V typ.)), the IC is automatically restored and the IGBT is turned on/off again by the input. When the VBS supply voltage drops VBSUVD (= 10 V typ.), the high-side IGBT output shuts down. When the VBS supply voltage reaches 0.5 V higher than the shutdown voltage (VBSUVR (= 10.5 V typ.)), the IGBT is turned on/off again by the input signal. Thermal shutdown The IC incorporates a thermal shutdown circuit to protect itself against excessive rise in temperature. When the temperature of this chip rises to the internal setting TSD due to external causes or internal heat generation, all IGBT outputs shut down regardless of the input. This protection function has hysteresis TSD (= 50 C typ.). When the chip temperature falls to TSD - TSD, the chip is automatically restored and the IGBT is turned on/off again by the input. Because the chip contains just one temperature-detection location, when the chip heats up due to the IGBT for example, the distance between the detection location and the IGBT (the source of the heat) can cause differences in the time taken for shutdown to occur. Therefore, the temperature of the chip may rise higher than the initial thermal shutdown temperature.

Description of Bootstrap Capacitor Charging and Its Capacitance
The IC uses bootstrapping for the power supply for high-side drivers. The bootstrap capacitor is charged by turning on the low-side IGBT of the same arm (approximately 1/5 of PWM cycle) while the high-side IGBT controlled by PWM is off. (For example, to drive at 20 kHz, it takes approximately 10 s per cycle to charge the capacitor.) When the VS voltage exceeds 3.8 V (55 % duty), the low-side IGBT is continuously in the off state. This is because when the PWM on-duty becomes larger, the arm is short-circuited while the low-side IGBT is on. Even in this state, because PWM control is being performed on the high-side IGBT, the regenerative current of the diode flows to the low-side FRD of the same arm, and the bootstrap capacitor is charged. Note that when the on-duty is 100 %, diode regenerative current does not flow; thus, the bootstrap capacitor is not charged. When driving a motor at 100 % duty cycle, take the voltage drop at 100 % duty (see the figure below) into consideration to determine the capacitance of the bootstrap capacitor. Capacitance of the bootstrap capacitor = Current dissipation (max) of the high-side driver x Maximum drive time /(VCC - VF (BSD) + VF (FRD) - 13.5) [F] VF (BSD) : Bootstrap diode forward voltage VF (FRD) : First recovery diode forward voltage Consideration must be made for aging and temperature change of the capacitor.

Note: Sweeps the BSU pin voltage from 15 V to decrease and monitors the VBB pin voltage. The BSU pin voltage when output is off defines the under voltage protection operating voltage. Also sweeps the BSU pin voltage from 6V to increase and change the HU pin voltage at 5V 0V 5V each time. It repeats similarly output is on. The BSU pin voltage when output is on defines the under voltage protection recovery voltage.
