HYBRID IC FOR DRIVING TRANSISTOR MODULES

DESCRIPTION

M57925L is a Hybrid Integrated Circuit designed for driving Transis­tor 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.
