Overview

The IR2104PBF is a high-voltage, high-speed power MOSFET and IGBT driver with independent high and low side referenced output channels. It is specifically designed for half-bridge applications and features a floating channel that allows for bootstrap operation up to +600V. This IC integrates cross-conduction prevention logic and internal deadtime to ensure robust power switching in demanding environments.

Why Choose This Part

The device simplifies circuit design by integrating cross-conduction prevention and a fixed internal deadtime, which protects power stages from shoot-through currents. Its wide supply range of 10V to 20V and tolerance to negative transient voltages make it highly reliable in noisy industrial switching environments.

Applications

Brushless DC (BLDC) Motor Drives
Used in the half-bridge power stage to drive high-side and low-side N-channel MOSFETs in motor inverter circuits.
Class D Audio Amplifiers
Provides the high-speed switching required for the output stage of high-efficiency audio power amplifiers.
DC-DC Converters
Ideal for synchronous buck or half-bridge topology converters where efficient high-side gate driving is required.
Battery Powered Inverters
Enables efficient power conversion for portable equipment by supporting logic-level inputs (3.3V, 5V, and 15V) and providing 270mA output current.

Getting Started

To implement the IR2104PBF, select a bootstrap capacitor and diode suitable for the high-side floating supply based on the switching frequency and MOSFET gate charge. Ensure the SD (Shutdown) pin is pulled high for normal operation, as it disables both drive channels when low. For prototyping, the 8-PDIP through-hole package is breadboard-compatible, while the IR2104S variant should be used for production surface-mount designs.
