The document describes the features and characteristics of the IRS2153D(S)PbF self-oscillating half-bridge driver IC, including 600V maximum voltage offset, 50% duty cycle, 180/260mA driver source/sink current, 15.4V Zener clamp, etc.
The IRS2153D(S)PbF is a self-oscillating half-bridge driver IC based on an advanced silicon platform. It incorporates a high-voltage half-bridge gate driver with a front-end oscillator similar to the industry-standard CMOS 555 timer. The device utilizes HVIC and latch-immune CMOS technologies for rugged monolithic construction and includes an internal bootstrap FET driver.
