Product Introduction

Overview

The FAN3224TMX-F085 is a high-speed, low-side gate driver from onsemi, part of the FAN3223-25 family. This dual-channel driver is designed to drive N-channel enhancement-mode MOSFETs in low-side switching applications. It provides high peak current pulses during short switching intervals, making it suitable for various power management and switching applications. The driver is available with either TTL or CMOS input thresholds and features internal circuitry for under-voltage lockout, ensuring the output remains low until the supply voltage is within the operating range.
