M57955L
HYBRID IC FOR DRIVING HIGH BETA TRANSISTOR MODULES
DESCRIPTION
M57955L is a Hybrid Integrated Circuit designed for driving High
Beta Transistor Modules QM50D Y-HB , etc., in an Inv erter application.
This device operates as an isolation amplifier 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 High Beta Transistor Modules for Inverter applications
