M57950L
HYBRID IC FOR DRIVING TRANSISTOR MODULES
DESCRIPTION
M57950L 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.
FEATURES
● Electrical isolation between input and output with integrated optocoupler. V
Large load and sink current driving capability
