A3906  
Low Voltage Stepper and Single/Dual DC Motor Driver  
Features and Benefits  
Description  
2.5 to 9 V operation  
Designed for pulse width modulated (PWM) control of low  
voltage stepper motors, and single and dual DC motors, the  
A3906 is capable of output currents up to 1 A per channel and  
operating voltages from 2.5 to 9 V.  
Internal PWM current limit control  
Synchronous rectification for reduced power dissipation  
Peak current output flag  
Undervoltage lockout  
Low RDS(on) outputs  
Small package  
Brake mode for DC motors  
Sleep function  
Crossover-current protection  
Thermal shutdown  
The A3906 has an internal fixed off-time PWM timer that  
sets a peak current based on the selection of a current sense  
resistor. An overcurrent output flag is provided that notifies  
the user when the current in the motor winding reaches the  
peak current determined by the sense resistor. The fault output  
does not affect driver operation.  
TheA3906isprovidedina20-contact,4 mm×4 mm,0.75 mm  
nominal overall height QFN, with exposed pad for enhanced  
thermal dissipation. It is lead (Pb) free, with 100% matte tin  
leadframe plating.  
Package: 20-contact QFN (suffix ES)  
Applications include the following:  
Digital still cameras (DSC)  
Cell phone cameras  
USB powered devices  
Battery powered devices
