FAN3122
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 (FAN312x T) or VDD- proportional CMOS input thresholds (FAN312x C). 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 Miller Drive™ architecture for the final output stage. This bipolar / MOSFET bination 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 mercial FAN3121/22 is available in a 3x3 mm 8- lead thermally- enhanced MLP package or an 8-...
