IR4427 Description

Short technical summary and product information.

The Infineon Technologies IR4427 is a high-speed, low-voltage dual low-side driver IC. It is designed to drive N-channel MOSFETs and IGBTs, offering a gate drive supply range from 6V to 20V. The device features matched propagation delays for both channels and CMOS Schmitt-triggered inputs for reliable operation.

 

Key electrical characteristics include an output current capability of 2.3A minimum and 3.3A maximum, with rise times as low as 10ns. The operating temperature range is -40°C to 150°C (TJ). The IR4427 is housed in an 8-PDIP package, suitable for through-hole mounting.

 

This gate driver is built using proprietary latch-immune CMOS technologies, ensuring ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs. The output drivers are designed with a high pulse current buffer stage to minimize driver cross-conduction, making it suitable for various power switching applications.
