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 (1MB pdf). 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 our 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.
For a smaller, lower-cost, single-channel alternative to this driver, please consider our DRV8838 carrier. The DRV8838 has the same operating voltage range as the DRV8835 and very similar current capabilities, and it uses the same PHASE/ENABLE control interface.
For higher-voltage alternatives to this driver, consider our A4990 and DRV8801 motor driver carriers.
We also carry a DRV8835 dual motor driver Arduino shield that makes it easy to incorporate this great driver into an Arduino project, as well as a DRV8835 motor driver kit for the Raspberry Pi.
- Dual-H-bridge motor driver: can drive two DC motors or one bipolar stepper motor
- Motor supply voltage: 0 V to 11 V
- Logic supply voltage: 2 V to 7 V
- Output current: 1.2 A continuous (1.5 A peak) per motor
- Motor outputs can be paralleled to deliver 2.4 A continuous (3 A peak) to a single motor
- Two possible interface modes: IN/IN (outputs mostly mirror inputs) or PHASE/ENABLE (one pin for direction and another for speed)
- Inputs are 3V- and 5V-compatible
- Under-voltage lockout on the logic supply and protection against over-current and over-temperature
- Reverse-voltage protection on the motor supply
- Compact size (0.7?×0.4?) with the form factor of a 14-pin DIP package
Two 1×7-pin breakaway 0.1? male headers are included with the DRV8835 dual motor driver carrier, which can be soldered in to use the driver with breadboards, perfboards, or 0.1? female connectors. (The headers might ship as a single 1×14 piece that can be broken in half.) The right picture above shows the two possible board orientations when used with these header pins (parts visible or silkscreen visible). You can also solder your motor leads and other connections directly to the board.
