FDMF5821DC Description

Short technical summary and product information.

The FDMF5821DC is an integrated circuit from On Semiconductor, functioning as a half-bridge driver with a high output current capability of 60A. It is designed for use in synchronous buck converter applications, offering efficient power management.

 

The device operates with an input supply voltage range of 4.5V to 5.5V and supports a load voltage range of 4.5V to 16V. Key electrical specifications include a typical Rds(on) of 470mOhm for the low side and 680mOhm for the high side. It features a PWM interface for control and includes fault protection mechanisms such as over-temperature and UVLO (Under-Voltage Lockout).

 

Packaged in a compact 31-PQFN (5x5 mm) format, the FDMF5821DC is suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The driver integrates features like a bootstrap circuit, latch function, and status flag, making it a versatile component for demanding power applications.

 

This component is part of On Semiconductor's PowerTrench® and SyncFET™ series. It is designed for inductive load types and is compliant with RoHS3 and REACH standards, though these compliance statuses are currently unverified.
