· Floating channel designed for bootstrap operation Fully operational to +600V Tolerant to negative transient voltage dV/dt immune
· Undervoltage lockout
· Programmable oscillator frequency
· Matched propagation delay for both channels
· Micropower supply startup current of 90 µA.
· Shutdown function turns off both channels
· Low side output in phase with RT

The IR2153Z 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 program-mable oscillator which is similar to the 555 timer. The output drivers of the IR2153Z feature a high pulse current 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 of the IR2153Z 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.
