FAN3121−F085/D Single 9-A High-Speed, Low-Side Gate Driver FAN3121, FAN3122

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 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 operating range. FAN312x drivers incorporate the MillerDrive™ architecture for the final output stage. This bipolar / MOSFET combination provides the highest peak current during the Miller plateau stage of the MOSFET turn−on / turn−off process. The FAN3121 and FAN3122 drivers implement an enable function on pin 3 (EN), previously unused in the industry −standard pin−out. The pin is internally pulled up to V DD for active HIGH logic and can be left open for standard operation. The AEC −Q100 automotive −qualified versions are available in 8−lead SOIC packages with and without exposed pad.
