Description of Protection Function
(1) Under voltage protection
This product 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
this product 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.)), this product is automatically restored and the IGBT is turned on again by
the input. DIAG output is reversed at the time of VCC under-voltage protection. When the VCC power
supply is less than 7 V, DIAG output isn't sometimes reversed. When the VBS supply voltage drops
VBSUVD (=9 V typ.), the high-side IGBT output shuts down.
When the VBS supply voltage reaches 0.5 V higher than the shutdown voltage (VBSUVR (=9.5 V typ.)), the
IGBT is turned on again by the input signal.
(2) Thermal shutdown
This product incorporates a thermal shutdown circuit to protect itself against the abnormal state when its
temperature rises excessively. 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
ΔTSD (=50°C typ.). When the chip temperature falls to TSD ΔTSD, 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.
(3) SD pin
SD pin is the input signal pin to shut down the internal output IGBT. Output of all IGBT is shut down after
delay times (2 μs typ.) when "L" signal is input to the SD pin from external circuit (MCU etc.). It is possible
to shut down IC when overcurrent and others is detected by external circuit. Shut down state is released by
all of IC input signal "L". At open state of SD pin, shut down function can not operate.
