Description
The IR51H737 is a high voltage, high speed, self-
oscillating half-bridge. Proprietary HVIC and latch
immune
CMOS
technologies,
HEXFET
power MOSFET technology, enable
ruggedized single package construction. 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. Propagation 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 300 volts.
