Industry-Standard Pin Out
The FAN3213 and FAN3214 dual 4 A gate drivers are
designed to drive N-channel enhancement-mode
MOSFETs in low-side switching applications by
providing high peak current pulses during the short
switching intervals. They are both 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. In
addition, the drivers feature matched internal
propagation delays between A and B channels for
applications requiring dual gate drives with critical
timing, such as synchronous rectifiers. This also
enables connecting two drivers in parallel to effectively
double the current capability driving a single MOSFET.
4.5 to 18 V Operating Range
5 A Peak Sink/Source at VDD = 12 V
4.3 A Sink / 2.8 A Source at VOUT = 6 V
TTL Input Thresholds
Two Versions of Dual Independent Drivers:

Dual Inverting (FAN3213)
Dual Non-Inverting (FAN3214)

MillerDrive™ Technology
12 ns / 9 ns Typical Rise/Fall Times with 2.2 nF
Load
The FAN3213/14 drivers incorporate MillerDrive™
architecture for the final output stage. This bipolar-
MOSFET combination provides high 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.

Standard SOIC-8 Package
Rated from –40°C to +125°C Ambient
Automotive Qualified to AEC-Q100 (F085 Version)
The FAN3213 offers two inverting drivers and the
FAN3214 offers two non-inverting drivers. Both are
offered in a standard 8-pin SOIC package.
