IR2302S

IR2302S Description

The IR2302S from Infineon Technologies is a high-voltage, high-speed half-bridge gate driver IC designed for synchronous power MOSFET and IGBT control. Operating within a 5V to 20V supply range, it features dual independent drivers with peak output currents of 200mA (source) and 350mA (sink), ensuring robust switching performance. The device supports bootstrap operation with a high-side voltage rating of 600V, making it suitable for high-voltage applications. With 130ns rise and 50ns fall times (typical), it enables efficient high-frequency switching, reducing power losses in power conversion systems.
