The onsemi XS™ DrMOS FDMF6823B is a high-performance half-bridge driver designed for synchronous buck converters. This DrMOS component integrates power MOSFETs and a driver IC within a compact 40-PQFN (6x6) package, facilitating efficient power delivery. It offers a continuous output current of 55A per channel with a peak output capability also at 55A. Key features include a bootstrap circuit for high-side driver operation and diode emulation for enhanced efficiency. Fault protection mechanisms such as over-temperature, shoot-through, and undervoltage lockout (UVLO) are integrated for robust operation. The FDMF6823B supports PWM and logic interfaces and is suitable for inductive, capacitive, and resistive loads. Operating across a load voltage range of 3V to 16V and a supply voltage of 4.5V to 5.5V, it functions reliably within an ambient temperature range of -40°C to 125°C. This component finds application in demanding power supply designs across various industries requiring efficient voltage regulation.
