IR2111 Half Bridge Driver IC DIP 8 Package

IR2111 Half Bridge Driver IC DIP 8 Package

The IR2111 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 provides level-shifted high-side drive capability along with a powerful low-side driver, enabling efficient control of high-power switching devices.

The IC uses bootstrap supply technology to generate the floating high-side gate drive voltage and includes undervoltage lockout (UVLO) protection to ensure safe operation. Packaged in a compact DIP-8 through-hole package, the IR2111 is suitable for prototyping, educational projects, and industrial power electronics designs.
