FAN3122 - (FAN3121 / FAN3122) Low-Side Gate Driver

Download the FAN3122 datasheet PDF. This datasheet also covers the FAN3121 variant, as both devices belong to the same (fan3121 / fan3122) low-side gate driver family and are provided as variant models within a single manufacturer datasheet.

Description

The FAN3121 and FAN3122 MOSFET drivers are designed to drive N-channel enhancement MOSFETs in low-side switching applications by providing high peak current pulses.

The drivers are available with either TTL (FAN312xT) or CMOS (FAN312xC) input thresholds.

Features

  • Industry-Standard Pin-out with Enable Input 4.5 to 18V Operating Range 11.4A Peak Sink at VDD = 12V 9.7A Sink / 7.1A Source at VOUT = 6V Inverting Configuration (FAN3121) and Non-Inverting Configuration (FAN3122) Internal Resistors Turn Driver Off If No Inputs 23ns/19ns Typical Rise/Fall Times with 10nF Load 20ns Typical Propagation Delay Time Choice of TTL or CMOS Input Thresholds MillerDrive™ Technology Available in Therma.
