FAN7391MX

The FAN7391MX is a monolithic high- and low-side gate-drive integrated circuit from On Semiconductor, designed to drive high-speed MOSFETs and IGBTs operating up to 600V. It features a buffered output stage with NMOS transistors optimized for high pulse current driving and minimal cross-conduction.

This device utilizes high-voltage process and common-mode noise-canceling techniques for stable operation of the high-side driver under high-dv/dt noise conditions. An advanced level-shift circuit allows high-side gate driver operation up to -9.8V typical for VBS = 15V. The integrated advanced input filter on HIN provides protection against short-pulsed input signals caused by noise, and the UVLO circuit prevents malfunction when VDD and VBS are below specified thresholds.

With a typical 4.5A sourcing and sinking current driving capability, the FAN7391MX is suitable for applications such as PDP sustain pulse drivers, motor drivers, switching mode power supplies, and high-power DC-DC converters. It operates within a supply voltage range of 10V to 20V and supports 3.3V and 5V input logic compatibility. The device is housed in a 14-SOIC package and is designed for surface mount.

Key electrical characteristics include a high-side voltage rating of 600V, output currents of 4.5A/4.5A, and rise times of 25ns/20ns. The operating temperature range is -40°C to 150°C (TJ). The FAN7391MX is a Pb-Free device.
