M57951L
HYBRID IC FOR DRIVING TRANSISTOR MODULES
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.
