Description

DC Motor Driver BoardDC Motor Driver Board

Description:

  • The DRV8871 device is a brushed DC motor driver for use in printers, appliances, industrial equipment and other small machines.
  • Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that can control the motor bidirectionally with peak currents up to 3.6A.
  • The input can be pulse width modulated (PWM) to control motor speed by selecting a current decay mode.
  • Setting both inputs low will enter a low-power sleep mode.
  • The DRV8871 device features a current regulation circuit that does not use an analog voltage reference or external sense resistor.
  • This novel solution uses standard low-cost, low-power resistors to set the current threshold.
  • The ability to limit current to a known level can significantly reduce system power requirements and the large capacitance needed to maintain stable voltage, especially during motor starting and stall conditions.
  • The device has complete fault and short circuit protection, including under voltage (UVLO), over current (OCP) and over temperature (TSD). After troubleshooting, the device will automatically resume normal operation.
