2A Low-Voltage PMOS-NMOS Bridge Driver  
Features  
Description  
The FAN3268 dual 2A gate driver is optimized to drive a  
high-side P-channel MOSFET and a low-side N-channel  
MOSFET in motor control applications operating from a  
voltage rail up to 18V. The driver has TTL input  
thresholds and provides buffer and level translation  
functions from logic inputs. Internal circuitry provides an  
under-voltage lockout function that prevents the output  
switching devices from operating if the VDD supply  
voltage is below the operating level. Internal 100k  
resistors bias the non-inverting output low and the  
inverting output to VDD to keep the external MOSFETs  
off during startup intervals when logic control signals  
may not be present.

MillerDrive™ Technology  
8-Lead SOIC Package  
The FAN3268 driver incorporates 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.

Motor Control with PMOS / NMOS Half-Bridge  
Configuration  
The FAN3268 has two independent enable pins that  
default to on if not connected. If the enable pin for non-  
inverting channel A is pulled low, OUTA is forced low; if  
the enable pin for inverting channel B is pulled low,  
OUTB is forced high. If an input is left unconnected,  
internal resistors bias the inputs such that the external  
MOSFETs are off.
