A3909 - Dual Full Bridge Motor Driver

Datasheet Summary

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.

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: ▫ Output to supply short ▫ Output to GND short ▫ Output load short.
