2,The logic inputs of the DRV8871 can be pulsewidth modulated (PWM) to control motor speed, and users can choose from different current-decay modes for this control process.
1,The DRV8871 is a brushed-DC motor driver applied in printers, appliances, industrial equipment, and other small machines, which adopts an H-bridge driver composed of four N-channel MOSFETs (controllable via two logic inputs) to realize bidirectional motor control with a peak current of up to 3.6 A.
4,The DRV8871's ability to limit current to a known level can notably reduce the system's power requirements and the bulk capacitance required to maintain stable voltage, particularly in motor startup and stall scenarios.
3,The DRV8871 is equipped with advanced current-regulation circuitry that dispenses with an analog voltage reference or external sense resistor, instead using a standard low-cost, low-power resistor to set the current threshold.
5,The DRV8871 is fully protected against faults and short circuits, covering undervoltage (UVLO), overcurrent (OCP), and overtemperature (TSD), and it will automatically resume normal functioning once the fault condition is eliminated.
