External Parts
Standard external parts are shown in the following table.
Part C1, C2, C3 R1 C4 R2 C5 C6 R3 C7 Recommended Value 25 V/2.2 F 0.62 1% (1 W) 10 V/1000 pF 5% 27 k 5% 25 V/10 F 10 V/0.1 F 5.1 k TBD Purpose Bootstrap capacitor Current detection PWM frequency setup PWM frequency setup Control power supply stability VREG power supply stability FG pin pull-up resistor Input power supply stability Remarks (Note 1) (Note 2) (Note 3) (Note 3) (Note 4) (Note 4) (Note 5) (Note 6)
Note 1: The required bootstrap capacitance value varies according to the motor drive conditions. The IC can operate at above the VBS undervoltage level, however, it is 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 for it. Note 2: The following formula shows the detection current: IO = VR / RIS (VR = 0.5 V typ.) Do not exceed a detection current of 1 A when using the IC. Note 3: With the combination of Cos and RREF 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.) fPWM = 0.65 / {Cos x (RREF + 4.25 k)} [Hz] RREF creates the reference current of the PWM triangular wave charge/discharge circuit. If RREF is set too small it exceeds the current capacity of the IC internal circuits and the triangular wave distorts. Set RREF to at least 9 k. Note 4: When using the IC, some 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 the noise elimination. Note 5: The FG pin is open drain. Note that when the FG pin is connected to a power supply with a voltage higher than or equal to the VCC, a protection circuit is triggered so that the current flows continuously. If not using the FG pin, connect to the GND. Note 6: If noise is detected on the Input signal pin, add a capacitor between inputs.
Handling precautions
(1) 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. The triangular wave oscillator circuit, with externally connected COS and RREF, 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. The PWM of this IC is controlled by the on/off state of the high-side IGBT. In the state where VBB voltage is low, and Duty100%, if a motor is made to lock, after load release may be unable to reboot. This is the high side ON of a just before lock, when a motor is locked in the state where VBB voltage is low. It is because time becomes long, bootstrap voltage falls, the decrease voltage protection of a high side operates and a high side output serves as OFF. In this case, since the level shift pulse for making a high side turn on is ungenerable, it cannot reboot. A level shift pulse is generated from the edge of a hole sensor output and the edge of a hall sensor output edge of an internal PWM signal, neither of the edge exists by the motor lock and Duty100% command. In order to reboot after locke, it is required for a high side input signal to enter in the state where it recovered to voltage with high side power supply voltage higher 0.5v than a decrease voltage protection voltage value. Since a high side input signal is created by the above-mentioned level shift pulse, it can reboot

by making Duty of PWM less than 100%, or turning a motor from the outside compulsorily, and creating edge to a hall sensor output. In order to enable the reboot after a lock as a system, it is necessary to restrict and obtain on motor specification so that the maximum of Duty may become less than 100%.
Description of Protection Function
(1) Over current protection The IC incorporates the 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 IS 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 the under voltage protection circuit 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 VCCUVR (= 11.5 V typ.) reaches 0.5 V higher than the shutdown voltage, the IC is automatically restored and the IGBT is turned on again by the input. When the VBS supply voltage drops (VBSUVD = 10 V typ.), the high-side IGBT output shuts down. When the VBSUVR (= 10.5 V typ.) reaches 0.5 V higher than the shutdown voltage, the IGBT is turned on again by the input signal. Thermal shutdown The IC incorporates the thermal shutdown circuit to protect itself against the abnormal state when its temperature rises excessively. When the temperature of this chip rises due to external causes or internal heat generation and the internal setting TSD, all IGBT outputs shut down regardless of the input. This protection function has hysteresis (TSD = 50C typ.). When the chip temperature falls to TSD - TSD, the chip is automatically restored and the IGBT is turned on 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 differences in distance from the detection location in the IGBT (the source of the heat) cause differences in the time taken for shutdown to occur. Therefore, the temperature of the chip may rise higher than the thermal shutdown temperature when the circuit started to operate.

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 ms 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 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 = Consumption current (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) : Flywheel diode forward voltage Care must be taken for aging and temperature change of the capacitor.
