Infineon IR2104STRPBF 600V Half-Bridge Gate Driver IC, SOIC-8

The IR2104STRPBF is a high-voltage half-bridge gate driver IC from Infineon Technologies, designed to drive power switching devices such as MOSFETs and IGBTs. It integrates high-side and low-side driver channels for power conversion, motor control, and other half-bridge switching applications.

The device supports high-side floating operation at voltages up to 600V and operates with a gate drive supply voltage ranging from 10V to 20V. Its logic inputs are compatible with 3.3V, 5V, and 15V signals. The integrated bootstrap-compatible high-side driver enables high-side and low-side power switch control, while undervoltage lockout (UVLO), internal deadtime, and cross-conduction prevention logic help improve switching circuit reliability.

The IR2104STRPBF also features a shutdown input that turns off both driver channels when activated. Its compact SOIC-8 surface-mount package makes it suitable for space-conscious PCB designs.

Typical applications include switched-mode power supplies, inverters, motor drives, industrial power control, and other power electronics systems. Before design integration, consult the official datasheet to verify pin assignments, output drive current, timing parameters, absolute maximum ratings, and external circuit requirements.
