Overview
The FAN3226TMPX, part of the FAN3226-29 family, is a dual 2 A high-speed, low-side gate driver designed by onsemi. This component is specifically engineered to drive N-channel enhancement-mode MOSFETs in low-side switching applications, providing high peak current pulses during short switching intervals. The driver is available with either TTL or CMOS input thresholds, making it versatile for various system designs. It features internal circuitry with an under-voltage lockout function, ensuring the output remains low until the supply voltage is within the operating range. The FAN3226TMPX also incorporates MillerDrive™ architecture, which combines bipolar and MOSFET technologies to minimize switching losses and provide high current during the Miller plateau stage of MOSFET turn-on and turn-off processes.
