The IRS21531DSPBF is a self-oscillating half-bridge Gate Driver IC using a more advanced silicon platform and incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. The HVIC and latch immune CMOS technologies enable rugged monolithic construction. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Noise immunity is achieved with low di/dt peak of the gate driver. It is based on the popular IR2153 self-oscillating half-bridge gate driver IC.
