Precaution:
The value of “R_ext” should be selected according to the guidelines in
Section 4.6.2 of Application Notes.
Also, the value of “R_ext” should be selected so that maximum limits, I_OHP
and I_OLP are not exceeded.
Hybrid Integrated Circuit
For Driving IGBT Modules
Description:
M57957L is a hybrid integrated cir-
cuit 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 (V_CMR : Typical
30kV/µs, Min. 15kV/µs)
ٗ Electrical Isolation between in-
put and output with opto-cou-
plers (V_iso = 2500,
V_RMS for 1 min.)
ٗ TTL compatible input interface
ٗ Two supply drive topology
ٗ Short differential of propa-
gation time (t_PLH, t_PHL 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:
V_CES = 600V Series
(up to 200A Class)
V_CES = 1200V Series
(up to 100A Class)
V_CES = 1400V Series
(up to 100A Class)
