Description

The DRV8870 device is a brushed-DC motor driver forprinters, appliances, industrial equipment, and other small machines. Two logic inputs control theH-bridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionallywith up to 3.6-A peak current. The inputs can be pulse-width modulated (PWM) to control motorspeed, using a choice of current-decay modes. Setting both inputs low enters a low-power sleepmode.

The DRV8870 device features integrated currentregulation, based on the analog input VREF and the voltage on the ISEN pin, which is proportionalto motor current through an external sense resistor. The ability to limit current to a known levelcan significantly reduce the system power requirements and bulk capacitance needed to maintainstable voltage, especially for motor startup and 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.
