A3909GLYTR-T Description

Short technical summary and product information.

The A3909GLYTR-T from Allegro Microsystems is a versatile dual full-bridge motor driver suitable for 12V medium power applications. It is designed to drive two DC motors or a single bipolar stepper motor in full- and half-step modes. The device operates from a power supply range of 4V to 18V and can deliver up to 1A of current per phase. Its outputs feature low RDS(on) for efficient operation.

Key features include thermal shutdown protection and overcurrent protection, safeguarding the device and the motor load. It also offers a low-power standby (Sleep) mode with zero current drain. The A3909GLYTR-T is supplied in a 10-pin MSOP package with an exposed thermal pad (suffix LY), designed for surface mounting.

This motor driver is ideal for applications requiring precise control of DC or stepper motors. Its robust protection features and wide operating voltage range make it a reliable choice for various automation and control systems. The device supports forward, reverse, brake, and coast modes for DC motors, and full- and half-step modes for stepper motors.
