The onsemi FDMF6705 is a DrMOS half-bridge driver from the XS™ DrMOS series, presented in a 40-PQFN (6x6) package. This component is engineered for high-efficiency synchronous buck converters, delivering up to 38A of output current per channel. It features integrated bootstrap circuitry and a status flag for enhanced operational monitoring. The device incorporates robust fault protection mechanisms, including over-temperature, shoot-through, and undervoltage lockout (UVLO). Operating from a 4.5V to 5.5V supply voltage, it supports load voltages from 3V to 24V. Mounting is via surface mount, and the operating temperature range is -40°C to 150°C (TJ). This component is suitable for demanding applications in computing, power supplies, and industrial automation. It is supplied on tape and reel.
