Key Features
- Integrated current sensing removes external sense resistors, reducing BOM cost and PCB area in stepper drive designs
- Up to 1/32 microstepping resolution enables smooth, low-noise motion control for precision positioning applications
- 4.5 V to 33 V wide supply voltage range accommodates 5 V, 12 V, and 24 V motor bus rails without redesign
- 3 A peak output current rating per coil supports higher-torque NEMA 17 and NEMA 23 stepper motor winding configurations
Applications
The DRV8886RHRT is well-suited for 3D printers, CNC router axes, and laboratory dispensing systems where smooth stepping and compact driver footprint are required. Its integrated current sense simplifies the PCB layout by removing the need for external shunt resistors on each motor winding. The 4.5 V to 33 V supply range and 1/32 microstepping mode make it equally applicable to desktop robotics and automated optical inspection equipment.

Frequently Asked Questions
How does DRV8886RHRT eliminate external current-sense resistors and what does that save on the PCB?
DRV8886RHRT uses an internal current-sense amplifier that monitors winding current without external shunt resistors. This removes at least 2 resistors per axis from the BOM, saves roughly 10 mm² to 20 mm² of PCB area per driver, and eliminates resistor power dissipation losses at 2 A coil current.
What microstepping modes does DRV8886RHRT support for reducing stepper motor vibration?
DRV8886RHRT supports full, half, 1/4, 1/8, 1/16, and 1/32 step modes selectable via logic pins. At 1/32 microstepping a 200-step motor produces 6400 microsteps per revolution, greatly reducing resonance and audible noise compared to full-step operation at equivalent speeds.
What supply voltage range does DRV8886RHRT accept for compatibility with different stepper motor bus voltages?
The DRV8886RHRT operates from a 4.5 V to 33 V motor supply, covering 5 V, 12 V, 24 V, and up to 33 V motor bus rails. This broad range allows the same driver IC to be used in low-voltage desktop devices and higher-voltage industrial axes without changing the circuit topology.
For a CNC router using NEMA 23 steppers, can DRV8886RHRT deliver enough current per winding?
Yes. The DRV8886RHRT delivers up to 2 A RMS and 3 A peak per winding, which covers typical NEMA 23 steppers rated 1.5 A to 2.8 A per phase. The 28-pin QFN package with exposed pad dissipates heat efficiently to the PCB copper, supporting sustained 2 A operation with adequate copper area.
