Notes

1. “Input ON voltage” indicates a value to turn on output stage IGBT.

“Input OFF voltage” indicates a value to turn off output stage IGBT.

At the time of output ON, set the input signal voltage Vin(on) Min. to 15V.

At the time of output OFF, set the input signal voltage 0V to Vin(off) Max.

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

signal is ON state : output form is open DRAIN) but the Fault signal doesn't latch.

After protection operation ends, it returns automatically within about 2ms (typ.) and resumes operation beginning

condition. So, after Fault signal detection, set OFF (Low) to all input signals at once.

However, the operation of pre-drive power supply low voltage protection (UVLO: it has a hysteresis about 0.2V is as

follows.

Upper side → There is no Fault signal output, but it does a corresponding gate signal OFF.

Incidentally, it returns to the regular operation when recovering to the normal voltage, but the latch

continues among input signal ON (High).

Lower side → It outputs Fault signal with gate signal OFF.

However, it is different from the protection operation of upper side, it is automatically resets and

resumes operation beginning condition when recovering to normal voltage. (The protection operation

doesn't latch by the input signal.)

3. When assembling the hybrid IC on the heat sink with M3 type screw, tightening torque range is 0.8 to 1.0 N·m.

4. The pre-drive low voltage protection is the feature to protect a device when the pre-driver supply voltage declines

with the operating malfunction. As for the pre-driver supply voltage decline in case of operation beginning, and so on,

we request confirmation in the set.
