STK5F4U3E2D-E
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 1ms to 3ms and resumes operation beginning
condition. So, after FAULT signal detection, set all input signal to OFF (Low) at once.How ever, 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 H-IC on the heat sink with M4 type screw, tightening torque range is 0.79Nm to 1.17Nm.
3. The pre-drive low voltage protection is the feature to protect a device when the pre-driver supply voltage falls
due to an operating malfunction.
4. When use the over-current protection with external resistors, please set the current protection level to be equal or
less than the rating of output peak current (Iop).
