Overview
The DRV8835DSSR, produced by Texas Instruments, is an integrated motor driver solution designed for low-voltage or battery-powered motion control applications. This device is particularly suited for cameras, consumer products, toys, and other similar applications. It features two H-bridge drivers, enabling it to drive two DC motors or one stepper motor, as well as other devices such as solenoids. The output driver blocks consist of N-channel power MOSFETs configured as H-bridges, with gate drive voltages generated by an internal charge pump. The DRV8835DSSR operates with a motor power supply voltage from 0 V to 11 V and a device power supply voltage from 2 V to 7 V, making it versatile for various power requirements.
