DESCRIPTION
M57951L 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 includes three independent circuits.
