3 Description

The DRV8811 device provides an integrated stepper

motor driver solution for printers, scanners, and other

automated equipment applications. The device has

two H-bridge drivers, as well as microstepping

indexer logic to control a stepper motor.

The output driver block consists of N-channel power

MOSFETs configured as full H-bridges to drive the

motor windings.

A simple STEP-and-DIR interface allows easy

interfacing to controller circuits. Step mode pins allow

for configuration of the motor in full-step, half-step,

quarter-step, or eighth-step modes. Decay mode and

PWM off-time are programmable.

Internal shutdown functions are provided for

overcurrent protection, short-circuit protection,

undervoltage lockout and overtemperature.

The DRV8811 device is packaged in a PowerPAD™

28-pin HTSSOP package with thermal pad.
