FAN3100TMPX

The FAN3100 2 A gate driver is designed to drive an N-channel enhancement-mode MOSFET in low-side switching applications by providing high peak current available with TTL input thresholds. Internal circuitry provides an under-voltage lockout function by holding the output LOW until the supply voltage is within the operating range. The FAN3100 delivers fast MOSFET switching performance, which helps maximize efficiency in high-frequency power converter designs.

FAN3100 drivers incorporate 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 switching 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. If one or both inputs are left unconnected, internal resistors bias the inputs such that the output is pulled LOW to hold the power MOSFET off.
