Overview
The onsemi FAN3122CMX is a high-speed, low-side MOSFET driver designed to drive N-channel enhancement MOSFETs in various switching applications. This driver is part of the FAN3122 series and is known for its high peak current pulses and robust performance. The FAN3122CMX features CMOS input thresholds and incorporates the MillerDrive™ architecture, which combines bipolar and MOSFET technologies to provide the highest peak current during the Miller plateau stage of the MOSFET turn-on and turn-off process. It also includes an enable function on pin 3, which is internally pulled up to VDD for active HIGH logic and can be left open for standard operation.
