The Texas Instruments DRV8842PWP is a fully integrated motor driver that packs the control logic and power stage into a single 28-HTSSOP package. It drives one brushed DC motor or one bipolar stepper motor using two internal N-channel Power MOSFET half-bridges, each rated for 3.5 A continuous output. The supply and load voltage range of 8.2 V to 45 V covers nominal rails commonly found in industrial automation, printer mechanisms, textile machinery, and general-purpose actuator drives. The parallel interface accepts simple step/direction or PWM signals, making it a drop-in for designs that don't need a serial bus.
Two half-bridges — one motor, not two
The output configuration is two half-bridges. That drives one brushed DC motor (forward/reverse/brake) or one bipolar stepper (full-step, half-step, or microstep via an external indexer). It does NOT drive two independent DC motors simultaneously — that takes a quad half-bridge part like the DRV8811. If your BOM calls for two separate brushed motors, the DRV8842PWP is not the right fit. For a single bipolar stepper, the parallel interface accepts step and direction inputs directly from an MCU or motion controller.
For dual-source planning, the closest functional peer in TI's portfolio is the DRV8811PWPR, but that part delivers four half-bridges at 1.9 A per bridge — a different output stage topology.
