FAN3122 Overview
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 input thresholds (FAN312xT) or VDD−proportional CMOS input thresholds (FAN312xC). Internal circuitry provides an under−voltage lockout function by holding the output low until the supply voltage is within the...
