Hybrid Integrated Circuit
For Driving IGBT Modules
Description:
M57959L is a hybrid integrated
circuit designed for driving n-channel
IGBT modules in any gate amplifier
application. This device operates
as an isolation amplifier for these
modules and provides the required
electrical isolation between the in-
put and output with an opto-coupler.
Short circuit protection is provided
by a built in desaturation detector.
A fault signal is provided if the
short circuit protection is activated.
Features:
□ Built in high CMRR opto-
coupler (V
CMR
: Typical
30kV/ms, Min. 15kV/ms)
□ Electrical Isolation between
input and output with opto-
couplers (V
iso
= 2500,

for 1 min.)
□ TTL compatible input interface
□ Two supply drive topology
□ Built in short circuit protection
circuit with a pin for fault output
Application:
To drive IGBT modules for inverter,
AC Servo systems, UPS, CVCF
inverter, and welding applications.
