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 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.
