IR21531PBF Description

Short technical summary and product information.

The Infineon Technologies IR21531PBF is a versatile self-oscillating half-bridge gate driver IC designed for efficient power management applications. It integrates a high-voltage half-bridge gate driver with a front-end oscillator, simplifying circuit design. Key electrical specifications include a 600V high-side voltage capability and a supply voltage range of 10V to 15.6V.

 

This device offers features such as integrated bootstrap diode (in IR21531D variants), micropower startup, and improved noise immunity through lower di/dt gate drivers. It also includes a shutdown feature on the CT pin for disabling outputs with a low-voltage control signal. The operating temperature range is -40°C to 125°C (TJ).

 

The IR21531PBF is supplied in an 8-DIP (0.300", 7.62mm) through-hole package, making it suitable for various PCB mounting requirements. Its design prioritizes ease of use, stable performance at startup, and robust ESD protection on all leads.
