DESCRIPTION
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.
The four inputs (IN1...
