IR2104 Half Bridge Driver IC DIP 8 Package

IR2104 Half Bridge Driver IC DIP 8 Package

The IR2104 is a high-voltage half-bridge gate driver IC designed to drive N-channel MOSFETs or IGBTs in half-bridge power converter and inverter applications. It integrates both high-side and low-side drivers in a compact form, providing efficient and reliable gate control for high-power switching devices.

The IC uses bootstrap supply technology for the high-side driver and includes built-in undervoltage lockout (UVLO) protection to ensure safe operation. With fixed dead-time and simplified logic control, the IR2104 enables robust half-bridge designs with minimal external components. Packaged in a DIP-8 through-hole package, it is well suited for prototyping, educational projects, and industrial power electronics.
