Precaution:
The value of “Rext” should be selected according to the guidelines in
Section 4.6.2 of Application Notes.
Also, the value of “Rext” should be selected so that maximum limits, IOHP
and IOLP are not exceeded.
Hybrid Integrated Circuit
For Driving IGBT Modules
Description:
M57958L 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-cou-
pler.
Features:
ٗ Built in high CMRR opto-
coupler (VCMR : Typical
30kV/µs, Min. 15kV/µs)
ٗ Electrical Isolation between in-
put and output with opto-cou-
plers (Viso = 2500,
VRMS for 1 min.)
ٗ TTL compatible input interface
ٗ Two supply drive topology
ٗ Short differential of propa-
gation time (tPLH, tPHL to Max.
1.5µs, Typical 1.0µs)
Application:
To drive IGBT modules for inverter,
AC Servo systems, UPS, CVCF in-
verter, and welding applications.
Recommended Modules:
VCES = 600V Series
(up to 400A Class)
VCES = 1200V Series
(up to 200A Class)
VCES = 1400V Series
(up to 200A Class)
