IR21531STRPBF Description

Short technical summary and product information.

The Infineon Technologies IR21531STRPBF is a self-oscillating half-bridge gate driver IC designed for efficient power management. It integrates a high-voltage half-bridge gate driver with a front-end oscillator, similar to the industry-standard CMOS 555 timer.

 

Key electrical specifications include a 600V maximum high-side voltage and a 15.6V zener clamp on Vcc. The device offers true micropower startup, tighter initial deadtime control, and improved noise immunity due to lower di/dt gate drivers. It operates with a supply voltage range of 10V to 15.6V and a typical supply current of 5mA.

 

The IR21531STRPBF is housed in an 8-SOIC surface mount package, making it suitable for various PCB designs. It features an RC input circuit and N-channel MOSFET gate type. The operating temperature range is from -40°C to 125°C (TJ).

 

This gate driver IC provides enhanced functionality and ease of use compared to previous generations. It includes a shutdown feature on the CT pin for disabling outputs with a low-voltage control signal, ensuring stable frequency profiles at startup and improved latch immunity.
