M57915L

DESCRIPTION

M57915L is a Hybrid Integrated Circuit designed for driving Transis-

tor Modules QM10XX, QM20XX, 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 circuits with a

opto-coupler, as well as its driving capability which only requires

single power supply.

FEATURES

q Electrical isolation between input and output with integrated opto-

coupler. Viso=2500Vrms

q Applicable with single power supply (7 ~ 9V)

q Applicable with TTL input

APPLICATION

To drive Transistor Modules for Inverter applications
