Dual Full Bridge Motor Driver

Description

Features and Benefits

• Low R_DS(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.

▫ Output to supply short

▫ Output to GND short

▫ Output load short
