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 fullscale

current or 1.4-A rms current (with proper PCB

ground plane for thermal dissipation and at 24 V and

TA = 25°C).

Smart tune 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, shortcircuits,

and overtemperature. Fault conditions are

indicated by a nFAULT pin.
