Description
The FAN3100 2A 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 driver is
available with either TTL (FAN3100T) or 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. 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 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. 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 FAN3100 is available in a lead-free finish 2x2mm
6-lead Molded Leadless Package (MLP), for smallest
size with excellent thermal performance, or industry-
standard 5-pin SOT23.
