3 Description
The DRV8880 is a bipolar stepper motor driver for
industrial applications. The device has two N-channel
power MOSFET H-bridge drivers and a microstepping
indexer. The DRV8880 is capable of driving 2.0 A full-
scale current or 1.4-A rms current (with proper PCB
ground plane for thermal dissipation and at 24 V and
TA = 25°C).
AutoTune™ automatically tunes stepper motors for
optimal current regulation performance and
compensates for motor variation and aging effects.
Additionally slow, fast, and mixed decay modes are
available.
The STEP/DIR pins provide a simple control
interface. The device can be configured in full-step up
to 1/16- step modes. A low-power sleep mode is
provided for very low quiescent current standby using
a dedicated nSLEEP pin.
Internal protection functions are provided for
undervoltage, charge pump faults, overcurrent, short-
circuits, and overtemperature. Fault conditions are
indicated by a nFAULT pin.
