Dual H-bridge driver for brushed DC and bipolar stepper motors
The Texas Instruments DRV8833CPWPR is a fully integrated motor driver that packs four half-bridge outputs into a single 16-PowerTSSOP package. It drives two brushed DC motors or one bipolar stepper motor, with each channel rated for 700 mA continuous output current. The supply and load voltage range of 2.7 V to 10.8 V covers common 3.3 V and 5 V logic rails as well as single-cell Li-ion and multi-cell alkaline battery packs. A PWM interface gives direct speed and direction control from a microcontroller or FPGA.
700 mA per channel — sizing for your motor load
Each of the four half-bridges is rated for 700 mA continuous output. That means a single brushed DC motor on one H-bridge gets 700 mA; a bipolar stepper using two H-bridges also gets 700 mA per winding. For applications like small pumps, cooling fans, solenoid valves, or compact linear actuators, this current level is a good fit. If your motor's stall current exceeds 700 mA, you will need to step up to a higher-current driver in the DRV88xx family.
Supply range 2.7 V to 10.8 V — rail compatibility
The single supply pin powers both the logic and the motor drive, so the 2.7 V to 10.8 V range must cover your motor's rated voltage and your MCU's logic level. At the low end, 2.7 V works with 3.3 V systems and near-depleted 2-cell alkaline packs. At the high end, 10.8 V suits 9 V battery-powered designs or lightly loaded 12 V rails that sag under load. No separate logic supply is needed — the internal regulator handles gate drive from the same pin.
Junction temperature rated to 150 °C
Motor windings and nearby power devices radiate heat; the 150 °C TJ max gives thermal margin in enclosed or high-ambient environments like engine bays, HVAC actuators, or outdoor robotics.
Package and footprint — 16-PowerTSSOP with exposed pad
The pad is the primary heat path — the PCB layout must include a copper land pattern and a grid of vias to the ground plane. Tape & Reel and Cut Tape options are available for the shipping medium.
