M57951L Datasheet, PDF (1/4 Pages) Mitsubishi Electric Semiconductor – HYBRID IC FOR DRIVING TRANSISTOR MODULES

MITSUBISHI HYBRID ICs
M57951L
DESCRIPTION
M57951L is a Hybrid Integrated Circuit designed for driving Transis-
tor Modules QM30DY, QM50DY, etc., in an Inverter application. This
device operates as an isolation amplifier for Transistor Modules due
to the electrical isolation between the input and output, and includes
three independent circuits.
FEATURES
q Three independent circuits are included.
Isolation voltage: Viso=2500Vrms
q Each circuit can be driven by single power supply
APPLICATION
To drive Transistor Modules for Inverter applications
