Detailed Product Description

PSHI 1522
Dual IGBT Driver
Feature , Parameter , Application
● ASIC dual IGBT driver
● Suitable for all IGBTs up to 1200V/1700V
● Half-bridge mode select,also two independent single drives
● Short circuit and over current protection by VCEsat monitoring
● Isolation due to nanometer amorphous transformer
● Supply undervoltage protection (<12.5V)
● Error memory
●Error "soft turn-off"
● Driver interlock top/bottom in half-bridge mode
● Dead time adjustable
● Internal isolated DC/DC power supply
● ±25A peak current output
● IGBT gate drive voltage+15V/-9V
● 350ns signal conversion time
● 110ns error signal feedback time
●110ns narrow pulse inhibit eliminate radio frequency interference
● Max. working frequency 200kHz
● Error chain function, low level active
●Turn-off spike restrain by "dynamic soft turn-off"
