Features

Typical Connection

Description

The IR53H(D)420 are complete high voltage, high speed, self-

oscillating half-bridge circuits. Proprietary HVIC and latch im-

mune CMOS technologies, along with the HEXFET ® power

MOSFET technology, enable ruggedized single package con-

struction. The front-end features a programmable oscillator which

functions similar to the CMOS 555 timer. The supply to the

control circuit has a zener clamp to simplify offline operation. The output features two HEXFETs in a half-bridge

configuration with an internally set deadtime designed for minimum cross-conduction in the half-bridge. Propa-

gation delays for the high and low side power MOSFETs are matched to simplify use in 50% duty cycle

applications. The device can operate up to the V
