MITSUBISHI HYBRID ICs
M57950L
DESCRIPTION
M57950L 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 features
a small outline of 10-pin SIP.
FEATURES
q Electrical isolation between input and output with integrated opto-
coupler.
Viso=2500Vrms
Large load and sink current driving capability
.................................................................. IOL=–1A (MAX)
................................................................ IOLP=–3A (MAX)
q Applicable with TTL input
q Small outline, 10-pin SIP package
APPLICATION
To drive Transistor Modules for Inverter applications
