DRV8871DDAR Description

The brushed-DC motor driver DRV8871DDAR is designed for printers, appliances, industrial equipment, and other small machines. The H-bridge driver, which is made up of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6 A peak current, is controlled by two logic inputs. To control motor speed, the inputs can be pulse-width modulated (PWM) utilizing a variety of current-decay techniques. Both inputs are set to low to enter a low-power sleep state.
