IR21844 Description

Short technical summary and product information.

The IR21844 from Infineon Technologies is a high-voltage, high-speed power MOSFET and IGBT driver. It features dependent high and low side referenced output channels, with a floating channel capable of operating up to 600V. This device is built using proprietary HVIC and latch-immune CMOS technologies for rugged monolithic construction.

 

Key electrical specifications include a gate drive supply range of 10V to 20V, logic voltage compatibility down to 3.3V, and output source/sink current capability of 1.4A/1.8A. The driver offers matched propagation delays for both channels and undervoltage lockout for both. It is suitable for driving N-channel power MOSFETs or IGBTs in high-side configurations.

 

Packaged in a 14-DIP through-hole format, the IR21844 is designed for applications requiring robust gate driving capabilities. Its design prioritizes noise immunity and driver cross-conduction minimization, making it a reliable choice for demanding power electronics designs.
