FOR DRIVING TRENCH-GATE IGBT

BLOCK DIAGRAM

DESCRIPTION

M57161L-01 is a hybrid IC designed to drive trench-

gate IGBT module with built in RTC.

This device can operate by an input of +15V because of

electrical isolation between the input and output by an

opto coupler,and the built in DC-DC converter isolated

between a pair of positive/negative outputs for gate

driving.

With built in protection circuits,this devices can maintain

a reverse bias for a predetermined time after the detec-

tion of an over current(short circuit). Therefore,the pro-

tective system operates with a margin of time.

The over current(short circuit) detector functions with

RTC circuit built in IGBT module to detect a drop of gate

voltage.
