Single 9-A High-Speed,
Low-Side Gate Driver

Overview

The FAN3121 and FAN3122 MOSFET drivers are designed to drive N-channel enhancement MOSFETs in low-side switching applications by providing high peakcurrent pulses. The drivers are available with either TTL input thresholds (FAN312xT) or VDD-proportional CMOS input thresholds (FAN312xC). Internal circuitry providesan 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 currentduring 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 upto VDD for active HIGH logic and can be left open for standard operation.The commercial FAN3121/22 is available in a 3x3 mm 8-lead thermally-enhanced MLP package or an 8-lead SOIC package. The AEC-Q100 automotive-qualified versions are available in the 8-lead SOIC package.
