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 inputted 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.
