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.

Paralleling the outputs is possible for higher amperage single DC motor applications.

Low RDS(on) outputs.
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: ▫ Output to supply short ▫ Output to GND short ▫ Output load short.
