FAN3121TMX

The FAN3121 MOSFET drivers are designed to drive N-channel enhancement MOSFETS in loveside switching applications by providing high peak current pulses. The drivers are availabl with either TTL input thresholds (FAN312xT) or VDD-proportional CMOS input thresholds (FAN312xC). Internal circuitry provides an under-voltage locktllt function by holding the output Iow unit the supply voltage 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 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 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.
