Description for the DRV8871
The DRV8871 deviceis a brushed-DC motor driver for printers, appliances, industrial equipment, and other smallmachines. Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETsthat can control motors bidirectionally with up to 3.6-A peak current. The inputs can bepulse-width modulated (PWM) to control motor speed, using a choice of current-decay modes. Settingboth inputs low enters a low-power sleep mode.
The DRV8871 devicehas advanced current-regulation circuitry that does not use an analog voltage reference or externalsense resistor. This novel solution uses a standard low-cost, low-power resistor to set the currentthreshold. The ability to limit current to a known level can significantly reduce the system powerrequirements and bulk capacitance needed to maintain stable voltage, especially for motor startupand stall conditions.
The device is fully protected from faults and short circuits, including undervoltage(UVLO), overcurrent (OCP), and overtemperature (TSD). When the fault condition is removed, thedevice automatically resumes normal operation.
