Overview

The FL3100T 2 A gate driver is 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 FL3100T has two inputs that can be configured to operate in non-inverting (IN) mode with a DIM pin for PWM dimming control of the LED Driver. High accuracy PWM dimming control required in smart LED drivers is possible by adjusting the duty ratio of the DIM input. 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.
The driver is available with fixed TTL input thresholds. Internal circuitry provides an under-voltage lockout function by holding the output LOW until the supply voltage is within operating range. The FL3100T delivers fast MOSFET switching performance, which helps maximize efficiency in high-frequency LED driver designs.
The FL3100T is available in a 5-pin, SOT23 or a 2 x 2 mm, 6-lead, Molded Leadless Package (MLP) for the smallest size with excellent thermal performance.
