Notes

1. When the internal protection circuit operates, a Fault signal is turned ON (When the Fault terminal is low level,

Fault signal is ON state : output form is open DRAIN) but the Fault signal does not latch.After protection

operation ends,it returns automatically within about 18ms to 80ms and resumes operation beginning condition.

So, after Fault signal detection, set all input signals to OFF (Low) at once.However, the operation of pre-drive

power supply low voltage protection (UVLO:with hysteresis about 0.2V) is as follows.

Upper side:

The gate is turned off and will return to regular operation when recovering to the normal voltage, but the latch

will continue till the input signal will turn ‘low’.

Lower side:

The gate is turned off and will automatically reset when recovering to normal voltage. It does not depend on

input signal voltage.

2. When assembling the IPM on the heat sink with M4 type screw, tightening torque range is 0.79 Nm to 1.17 Nm.

3. The pre-drive low voltage protection is the feature to protect devices when the pre-driver supply voltage falls

due to an operating malfunction.
