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. Pro-
prietary HVIC and latch immune CMOS technologies
enable ruggedized monolithic construction. The front
end features a programmable oscillator which is simi-
lar to the 555 timer. The output drivers feature a high
pulse current buffer stage and an internal deadtime
designed for minimum driver cross-conduction. Propa-
gation delays for the two channels are matched to sim-
plify 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.
