产品概述
The DRV8870DDAR is a 3.6A brushed DC motor driver in 8 pin SO PowerPAD package. The DRV8870 devICe is a brushed-DC motor driver for printers, appliances, industrial equipment and other small machines. Two logic inputs control H bridge driver which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6A peak current. The inputs can be PWM to control motor speed using a choice of current-decay modes. Setting both inputs low enters a low-power sleep mode. It features integrated current regulation based on the analogue input VREF and the voltage on the ISEN pin which is proportional to motor current through an external sense resistor. The ability to limit current to a known level can significantly reduce the system power requirements and bulk capacitance needed to maintain stable voltage especially for motor start-up and stall conditions. The device is fully protected from faults and short circuits, including undervoltage, overcurrent and overtemperature.
