MITSUBISHI HYBRID IC
M57161L-01
FOR DRIVING TRENCH-GATE IGBT
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.
