Description
The FAN3223-25 family of dual 4A gate drivers is
designed to drive N-channel enhancement-mode
MOSFETs in low-side switching applications by
providing high peak current pulses during the short
switching intervals. The driver is available with either
TTL or CMOS 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 FAN322X 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 FAN3223 offers two inverting drivers and the
FAN3224 offers two non-inverting drivers. Each device
has dual independent enable pins that default to ON if
not connected. In the FAN3225, each channel has dual
inputs of opposite polarity, which allows configuration
as non-inverting or inverting with an optional enable
function using the second 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.

Notes:
1. Estimates derived from thermal simulation; actual values depend on the application.
2. Theta_JL (ΘJL): 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.
3. Theta_JT (ΘJT): 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.
4. Theta_JA (ΘJA): 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, as specified in JEDEC standards JESD51-2, JESD51-5, and
JESD51-7, as appropriate.
5. 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 4. For the MLP-8 package, the board
reference is defined as the PCB copper connected to the thermal pad and protruding from either end of the package. For the
SOIC-8 package, the board reference is defined as the PCB copper adjacent to pin 6.
6. 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 4.
