SLVSCY8B – AUGUST 2015 – REVISED JULY 2016 DRV88703.6-A Brushed DC Motor Driver (PWM Control)
1 Features 3 Description The DRV8870 device is a brushed-DC motor driver
for printers, appliances, industrial equipment, and
other small machines. Two logic inputs control the Hbridge driver, which consists of four N-channel
MOSFETs that can control motors bidirectionally with
up to 3.6-A peak current. The inputs can be pulsewidth modulated (PWM) to control motor speed, using
a choice of current-decay modes. Setting both inputs
low enters a low-power sleep mode. 1 H-Bridge Motor Driver
