The onsemi XS™ DrMOS FDMF6840C3 is a highly integrated half-bridge driver designed for demanding synchronous buck converter applications. This advanced DrMOS solution integrates a high-side and low-side MOSFET with a driver IC into a compact 40-PQFN (6x6) package. It supports a load voltage range of 3V to 16V and a supply voltage of 4.5V to 5.5V, delivering up to 50A output current per channel. Key features include a bootstrap circuit for efficient high-side drive and a status flag for operational monitoring. The FDMF6840C3 incorporates robust fault protection mechanisms, including over-temperature, shoot-through, and undervoltage lockout (UVLO), ensuring reliable operation. Its surface mount design and tape & reel packaging facilitate high-volume manufacturing. This component is well-suited for applications in computing, data centers, and high-performance power management systems.
