M57915L
HYBRID IC FOR DRIVING TRANSISTOR MODULES
DESCRIPTION
M57915L is a Hybrid Integrated Circuit designed for driving Transistor 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
● Electrical isolation between input and output with integrated optocoupler. V
● Applicable with single power supply (7 ~ 9V)
● Applicable with TTL input
iso=2500Vrms
APPLICATION
To drive Transistor Modules for Inverter applications
