FAN3100CSX

FAN3100CSX is a 2A gate driver designed to drive an N-channel enhancement-mode MOSFET in low-side switching applications by providing high peak current pulses during the short switching intervals. The driver is available with CMOS (FAN3100C) input thresholds. Internal circuitry provides an under-voltage lockout function by holding the output LOW until the supply voltage is within the operating range. It delivers fast MOSFET switching performance, which helps maximize efficiency in high-frequency power converter designs. It incorporates MillerDrive architecture for the final output stage. This bipolar MOSFET combination provides high peak current during the Miller plateau stage of the MOSFET turn-on / turn-off process to minimize switching loss, while providing rail-to-rail voltage swing and reverse current capability. The FAN3100 also offers dual inputs that can be configured to operate in non-inverting or inverting mode and allow implementation of an enable function.
