Description
The FAN3216 and FAN3217 dual 2 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.
The FAN3216/17 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.
The FAN3216 offers two inverting drivers and the
FAN3217 offers two non-inverting drivers. Both are
offered in a standard 8-pin SOIC package.

All standard Fairchild Semiconductor products are RoHS compliant and many are also “Green” or going green. Green means
the products are RoHS compliant AND they have limits on additional substances of Chlorine, Bromine and Antimony.

3. Theta_JL (Θ

): Thermal resistance between the semiconductor junction and the bottom surface of all the leads
(including any thermal pad) that are typically soldered to a PCB.
4. Theta_JT (Θ
JT
): Thermal resistance between the semiconductor junction and the top surface of the package,
assuming it is held at a uniform temperature by a top-side heatsink.
5. Theta_JA (Θ
JA
): Thermal resistance between junction and ambient, dependent on the PCB design, heat sinking,
and airflow. The value given is for natural convection with no heatsink using a 2S2P board, as specified in
JEDEC standards JESD51-2, JESD51-5, and JESD51-7, as appropriate.
6. Psi_JB (ΨjB): Thermal characterization parameter providing correlation between semiconductor junction
temperature and an application circuit board reference point for the thermal environment defined in Note 5. For
the SOIC-8 package, the board reference is defined as the pcb copper adjacent to pin 6.
7. Psi_JT (ΨjT): Thermal characterization parameter providing correlation between the semiconductor junction
temperature and the center of the top of the package for the thermal environment defined in Note 5.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
