The 1/16-step microstepping is implemented with a built-in indexer, so the MCU only needs to send a step and direction pulse — no complex microstepping table or PWM timing generation on the host side. That saves firmware effort and keeps the MCU pin count low.

Product details
Frequently asked questions
What is the output current of DRV8885RHRT?
The DRV8885RHRT is rated for 1.5 A continuous output per coil. This is the figure to use for motor phase-current sizing and thermal derating calculations.
When sourcing DRV8885RHRT, what is the closest functional alternative?
The closest functional peer from TI is the DRV8811PWPR, which also uses four half-bridge outputs for a bipolar stepper and a logic interface. The DRV8811 delivers 1.9 A output and operates up to 150°C junction, but its load voltage is limited to 8 V — it cannot accept the 24 V or 37 V rails the DRV8885 handles. The DRV8885 is the better fit for 12 V to 37 V printer and motion applications.
