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.

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

for active HIGH logic and can be left open for

standard operation.

The FAN3121/22 is available in a 3x3mm 8-lead thermally-

enhanced MLP package or an 8-lead SOIC package.
