Dual 4A High-Speed, Low-Side Gate Drivers  
Features  
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.

Internal Resistors Turn Driver Off If No Inputs  
MillerDrive™ Technology  
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.

Rated from –40°C to +125°C Ambient  
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.
