FDMF3030

Full Half-Bridge (H Bridge) Drivers Overview

The FDMF3030 is a half-bridge gate driver integrated into a DrMOS module by onsemi, designed for synchronous buck converters. It operates within a supply voltage range of 4.5V to 5.5V and supports load voltages from 3V to 24V. The device features a 40-PQFN (6x6) package with an operating junction temperature range of -40°C to 150°C. Typical on-resistance values are 900 mΩ for the low-side and 800 mΩ for the high-side MOSFETs. It includes bootstrap circuitry, diode emulation, status flags, and protection against overtemperature, shoot-through, and under-voltage lockout.
