FAN3226 / FAN3227 / FAN3228 / FAN3229  
Dual 2A High-Speed, Low-Side Gate Drivers  
Features  
Description  
The FAN3226-29 family of dual 2A 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  
enables connecting two drivers in parallel to effectively  
double the current capability driving a single MOSFET.

Internal Resistors Turn Driver Off If No Inputs  
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.

Typical Propagation Delay Under 20ns Matched  
within 1ns to the Other Channel  
The FAN3226 offers two inverting drivers and the  
FAN3227 offers two non-inverting drivers. Each device  
has dual independent enable pins that default to ON if  
not connected. In the FAN3228 and FAN3229, 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.
