In the case without the instruction, the voltage standard is – terminal = VSS terminal voltage.
*1 Surge voltage developed by the switching operation due to the wiring inductance between the + and –terminals.
*2 VD1 = between VB1-U, VD2 = VB2-V, VD3 = VB3-W, VB4 = VDD-VSS, terminal voltage.
*3 Flatness of the heat-sink should be lower than 0.25mm.
*4 The test condition is AC 2500V, 1 second.
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 0V to VIH (MAX).
At the time of output OFF, set the input signal voltage VIL (MIN) to 5V.
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 18ms to 80ms and resumes operation beginning
condition. So, after Fault signal detection, set OFF (HIGH) to all input signals at once.
However, the operation of pre-drive power supply low voltage protection (UVLO: it has a hysteresis about 0.3V) is
