A3909 Overview
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.
A3909 Key Features
- 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
