Data Sheet No. PD60259 ADVANCE INFORMATION IRS2453D(S)PbF SELF-OSCILLATING FULL-BRIDGE DRIVER IC Features Integrated 600V Full-Bridge Gate Driver CT, RT programmable oscillator 15.6V Zener Clamp on VCC Micropower Startup Logic Level Latched Shutdown Pin Non-latched shutdown on CT pin (1/6th VCC) Internal bootstrap FETs Excellent Latch Immunity on All Inputs & Outputs ESD Protection on All Pins 14-lead SOIC or PDIP package 1.0 usec (typ.) internal deadtime Description The IRS2453D is based on the popular IR2153 self-oscillating half-bridge gate driver IC, and incorporates a high voltage fullbridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. HVIC and latch immune CMOS technologies enable ruggedized 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 drivers, and with a undervoltage lockout hysteresis greater than 1.5V. The IRS2453D also includes latched and non-latched shutdown pins.

All voltage parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
