Description

The IR2155 is a high voltage, high speed, self-

oscillating power MOSFET and IGBT driver with both

high and low side referenced output channels. Pro-

prietary HVIC and latch immune CMOS technolo-

gies enable ruggedized monolithic construction.

The front end features a programmable oscillator

which is similar to the 555 timer. The output drivers

feature a high pulse current buffer stage and an in-

ternal deadtime designed for minimum driver cross-

conduction. Propagation delays for the two

channels are matched to simplify use in 50% duty

cycle applications. The floating channel can be

used to drive an N-channel power
