Power chip

The FAN3121 and FAN3122 MOSFET drivers are suitable for driving N-channel enhancement-mode MOSFETs in low-side switching applications by supplying high peak current pulses. The driver is available with TTL input threshold (FAN312xT) or VDD ratiometric CMOS input threshold (FAN312xC). Internal circuitry holds the output low until the supply voltage is within operating range, providing undervoltage lockout. The FAN312x drivers integrate the MillerDrive architecture for the final output stage. This bipolar/MOSFET combination provides the highest peak current during the Miller settling period of the MOSFET turn-on/turn-off. The FAN3121 and FAN3122 drivers perform an enable function on pin 3 (EN), previously not required in the industry standard pinout. The pin is internally pulled up to VDD for active high logic and can be left open in standard operation. The commercial FAN3121/22 features a 3x3mm 8-lead thermally enhanced MLP encapsulation or an 8-lead SOIC encapsulation.
