DRV8811 描述

The DRV8811 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 for each consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. A simple step/direction interface allows easy interfacing to controller circuits. Pins allow 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 over current protection, short circuit protection, under-voltage lockout and overtemperature. The DRV8811 is packaged in a PowerPAD™ 28-pin HTSSOP package with thermal pad (Eco-friendly: RoHS and no Sb/Br).
