FDMF6823

Full Half-Bridge (H Bridge) Drivers Overview

The FDMF6823 is an XS™ DrMOS module from onsemi, integrating a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a 40-pin PQFN (6x6 mm) package. It supports synchronous buck DC-DC applications with a supply voltage range of 4.5V to 5.5V and load voltage up to 16V. The device delivers output currents of 50A or 60A depending on the suffix, with typical Rds(on) of 1 ohm for both high-side and low-side switches. Operating temperatures span -40°C to 150°C junction, featuring PWM input, UVLO, over-temperature protection, and adaptive gate drive timing.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify specific suffix requirements as variants like FDMF6823A and FDMF6823C exist with different current ratings and status. Confirm availability since some versions are marked obsolete. Check datasheet for exact pinout and thermal characteristics matching your PCB layout. Ensure compatibility with 5V logic PWM inputs and required bootstrap circuitry.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select based on required output current capability (50A vs 60A) and specific feature set such as state flags or disable functions. Consider the 6x6mm package constraints for thermal management. Verify that the integrated bootstrap diode meets your voltage requirements. Evaluate if the skip-mode functionality aligns with your efficiency targets at light loads.
