The A3909 is a dual full bridge motor driver designed to control two DC motors or a single bipolar stepper motor, with a supply voltage range of 4 to 18 V and per-phase output current up to 1 A. It is offered in a 10-pin SSOP package with an exposed thermal pad (LY suffix) or a standard 10-pin SSOP (LN suffix); the A3909GLNTR-T uses the LN package. It includes thermal shutdown protection, overcurrent protection, and low-power standby mode with less than 10 µA current drain. Parallel operation of outputs enables 1.8 A for a single DC motor. The operating ambient temperature range is -40 to 105 °C, and the maximum junction temperature is 150 °C.
The A3909 offers a versatile solution for driving two DC motors or a single stepper motor, with independent full-bridge control for each. Supports a wide power supply range (4V-18V) and output currents up to 1A per phase, with the option for parallel operation at higher currents.
