IR2151 IC DIP8 MOSFET Driver

IR2151 IC Features

  • Fully operational to +600V
  • Tolerant to negative transient voltage
  • dV/dt immune
  • Undervoltage lockout
  • Programmable oscillator frequency
  • VOFFSET Duty Cycle IO+/VOUT Deadtime (typ.) 600V max. 1.2 µs
  • Matched propagation delay for both channels Low side output in phase with RT



The IR2151 IC is a high voltage, high speed, self-oscillating 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 dead designed for minimum driver cross-conduction. Propagation delays for the two channels are matched to simplify use in 50% of 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 to 600 volts.
