FDMF6705B Description

Short technical summary and product information.

The FDMF6705B from ON Semiconductor is a high-performance Full Half-Bridge Driver IC. It is engineered for use in synchronous buck converter applications, offering a robust current handling capability of 38A.

 

This DrMOS technology driver operates within a voltage range of 3V to 24V and is designed for surface mount installation in a 40-PQFN (6x6) package. Key electrical specifications include a typical on-resistance of 1 Ohm for both low-side and high-side MOSFETs. The device incorporates essential features such as a bootstrap circuit and a status flag for enhanced monitoring and control.

 

For operational reliability, the FDMF6705B includes comprehensive fault protection mechanisms, covering over-temperature conditions, shoot-through events, and undervoltage lockout (UVLO). It operates across a wide temperature spectrum, from -40°C to 150°C (TJ), making it suitable for demanding environments. The interface is PWM compatible, facilitating integration into various power management designs.

 

This component is suitable for applications requiring efficient and reliable power conversion. Its design considerations include load type compatibility with inductive loads and a half-bridge output configuration.
