Packages
The IR2151 is a high voltage, high speed, self-os-
cillating 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 fea-
tures a programmable oscillator which is similar to the
555 timer. The output drivers feature a high pulse cur-
rent buffer stage and an internal 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 MOSFET or IGBT
in the high side configuration that operates off a high
voltage rail up to 600 volts.
