DRV8835 Dual Motor Driver Carrier
This tiny breakout board for TI’s DRV8835 dual motor driver can deliver 1.2 A per channel continuously (1.5 A peak) to a pair of DC motors, and it supports two possible control interfaces for added flexibility of use: IN/IN and PHASE/ENABLE. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering up to two small, low-voltage motors. The carrier board has the form factor of a 14-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
Overview
Texas Instruments’ DRV8835 is a tiny dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 0 V to 11 V. It can supply up to about 1.2 A per channel continuously and can tolerate peak currents up to 1.5 A per channel for a few seconds, making it an ideal driver for small motors that run on relatively low voltages. The DRV8835 is a great IC, but its small, leadless package makes it difficult for the typical student or hobbyist to use; our breakout board gives this driver the form factor of a 14-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1″ perfboards. Since this board is a carrier for the DRV8835, we recommend careful reading of the DRV8835 datasheet. The board ships populated with SMD components, including the DRV8835, and adds a FET for reverse battery protection.
Alternative driver options
This board is very similar to the DRV8833 dual motor driver carrier in operating voltage range and continuous current rating, but the DRV8835 has a lower minimum operating voltage, offers an extra control interface mode, and is 0.1″ smaller in each dimension. The DRV8833 has a higher peak current rating (2 A per channel vs 1.5 A), optional built-in current-limiting, and no need for externally supplied logic voltage.
