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.
