Product Summary

The IR2151STR 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 IR2151STR features a programmable oscillator which is similar to the 555 timer. The IR2151STR features a high pulse current buffer stage and an internal deadtime designed for minimum driver cross-conduction.
