General Description

The FAN3111 1A gate driver is designed to drive an N-channel enhancement-mode MOSFET in low-side switching applications.

Two input options are offered: FAN3111C has dual CMOS inputs with thresholds referenced to VDD for use with PWM controllers and other input-signal sources that operate from the same supply voltage as the driver. For use with low-voltage controllers and other input signal sources that operate from a lower supply voltage than the driver, that supply voltage may also be used as the reference for the input thresholds of the FAN3111E. This driver has a single, non-inverting, low-voltage input plus a DC input VXREF for an external reference voltage in the range 2 to 5V.

The FAN3111 is available in a lead-free finish industry-standard 5-pin SOT23.
