Shutdown function

The device is equipped with three half-bridge IC gate drivers and integrates a comparator for fault detection.

input pin (CIN) can be connected to an external shunt resistor for current monitoring.

Since the comparator is embedded in the U IC gate driver, in case of fault it disables directly the U outputs,

whereas the shutdown of V and W IC gate drivers depends on the RC value of the external SD circuitry, which

fixes the disabling time.

For an effective design of the shutdown circuit, please refer to Application note AN4966.
