Description

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.
