Description
The IR51H(D)XXX 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 construc-
tion. The front-end features a programmable oscillator which func-
tions 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 in-
ternally set deadtime designed for minimum cross-conduction in
the half-bridge. Propagation delays for the high and low side
