Description

The DRV8886AT is a stepper motor driver for

industrial and consumer end equipment applications.

The device is fully integrated with two N-channel

power MOSFET H-bridge drivers, a microstepping

indexer, and integrated current sensing. The

DRV8886AT is capable of driving up to 2-A full scale

or 1.4-A rms output current (24-V and TA = 25°C,

dependent on PCB design).

The DRV8886AT uses an internal current sense

architecture to eliminate the need for two external

power sense resistors saving PCB area and system

cost. The DRV8886AT uses an internal PWM current

regulation scheme adjustable between smart tune

adaptive decay technology, slow, and mixed decay

options. Smart tune adaptive decay technology

automatically adjusts for optimal current regulation

performance and compensates for motor variation

and aging effects.

A simple STEP/DIR interface allows an external

controller to manage the direction and step rate of the

stepper motor. The device can be configured in

different step modes ranging from full-step to 1/16

microstepping. A low-power sleep mode is provided

for very low standby quiescent standby current using

a dedicated nSLEEP pin.

Device protection features are provided for supply

undervoltage, charge pump faults, overcurrent, short

circuits, and overtemperature. Fault conditions are

indicated by the nFAULT pin.
