The IR2155 is a high voltage, high speed, selfoscillating
power MOSFET and IGBT driver with both
high and low side referenced output channels. Proprietary
HVIC and latch immune CMOS technologies
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 internal
deadtime designed for minimum driver crossconduction.
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 MOSFET or IGBT in the high side configuration that
operates off a high voltage rail up to 600 volts.
