The Texas Instruments DRV8860PW is a fully integrated low-side driver that packs eight NMOS open-drain outputs, each rated for 200 mA, into a 16-pin TSSOP package. It handles brushed DC motors and unipolar steppers, plus general-purpose inductive loads like relays, solenoids, and lamps. The SPI interface lets a host controller shift in data for all eight channels over three or four wires — no dedicated PWM timer pins needed on the MCU side. Supply and load voltage share the same 8 V to 38 V rail, so one unregulated supply powers both the logic and the output stage.

Product details
Frequently asked questions
What is the DRV8860PW alternative or equivalent part?
The closest functional peer is the DRV8811PWPR, which provides four half-bridge outputs rated for 1.9 A and supports bipolar steppers. The DRV8860PW offers eight low-side outputs at 200 mA for unipolar steppers and general-purpose loads — the choice depends on whether your load needs half-bridge drive or eight independent low-side switches.
How do I interface DRV8860PW with SPI?
The DRV8860PW uses a standard SPI interface: connect SCLK, SDI, and CS to the host MCU. Data shifted in on SDI controls the eight output states; the device does not have a data-out pin, so no MISO connection is needed. The SPI clock rate is not specified in this listing — refer to the datasheet for timing requirements.
