Description

The FAN3100 2 A gate driver is designed to drive an N-

channel

enhancement-mode

MOSFET

in

low -side

sw itching applications by providing high peak current

pulses during the short sw itching intervals. The driver is

available

w ith

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 w ithin the operating range.

The

FAN3100

delivers

fast

MOSFET

sw itching

performance, w hich helps maximize efficiency in high-

frequency pow er 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

sw itching loss, w hile providing rail-to-rail voltage sw ing

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

pow er MOSFET off.

The FAN3100 is available in a lead-free finish, 2x2 mm, 6-

lead, Molded Leadless Package (MLP) for the smallest

size w ith excellent thermal performance; or industry-

standard, 5-pin, SOT23.
