FAN3122CMX

FAN3122CMX is a MOSFET driver designed to drive N-channel enhancement MOSFETs in low-side switching applications by providing high peak current pulses. The driver available with 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 driver incorporates 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 driver implements an enable function on pin 3 (EN), previously unused in the industry-standard pin-out. The pin is internally pulled up to VDD for active HIGH logic and can be left open for standard operation. Typical applications include synchronous rectifier circuits, high-efficiency MOSFET switching, switch-mode power supplies, DC-to-DC converters and motor control.
