FDMF6823A

Full Half-Bridge (H Bridge) Drivers Overview

The FDMF6823A is an ultra-compact DrMOS module from the XS™ series, integrating a half-bridge driver and power MOSFETs in a 40-PQFN (6x6 mm) package. It supports a supply voltage of 4.5V to 5.5V and drives loads between 3V and 16V. The device delivers 60A output current with typical on-resistance of 1 ohm for both high-side and low-side switches. Operating junction temperature ranges from -40°C to 150°C. Key features include PWM interface, bootstrap circuit, status flags, and protections against over-temperature, shoot-through, and under-voltage lockout.
