Dual Full Bridge Low Voltage Motor Driver  
Features and Benefits  
Low RDS(on) outputs  
Full- and half-stepping capability  
Small package  
Description  
The A3901 is a dual full-bridge motor driver, designed for low  
voltageportableapplicationsinvolvingbipolarstepperorbrush  
dc motors. The outputs have been optimized for low voltage  
Forward, reverse, and brake modes for dc motors  
Sleep mode with zero current drain  
PWM control up to 250 kHz  
Crossover-current protection  
Thermal shutdown (TSD)  
drop, with currents up to ±400 mA (±800 mA with outputs  
paralleled) and an operating voltage range of 2.5 to 5.5 V.

in full- or half-step mode, or dc motors in forward, reverse, or  
brake mode. The inputs can be PWMed for current or speed  
control at frequencies up to 250 kHz.  
Internal protection circuitry includes thermal shut down (TSD)  
and crossover (shoot-through) protection.  
The A3901 is supplied in a 3 x 3 x 0.75 mm nominal, 10-lead  
DFN/MLPpackage, with exposed thermal pad (package “EJ”).  
This small footprint package is lead (Pb) free, with 100% matte  
tin leadframe plating.
