Dual Full Bridge Motor Driver  
Description  
Features and Benefits  
• Low RDS(on) outputs  
The A3909 is a dual full bridge motor driver, designed for  
12 V medium power applications. The outputs are rated for  
operation through a power supply range of 4 to 18 V, and  
capable of up to 1 A per phase.  
• Drives two DC motors or single stepper motor  
• Low power standby (Sleep) mode with zero current drain  
• Thermal shutdown protection  
• Parallel operation option for 1.8 A, single DC motor  
• Overcurrent protection:  
Paralleling the outputs is possible for higher amperage single  
DC motor applications.
