3 Description
The DRV8871 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.
The DRV8871 device has advanced currentregulation
circuitry that does not use an analog
voltage reference or external sense resistor. This
novel solution uses a standard low-cost, low-power
resistor to set the current threshold. 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 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, the device automatically
resumes normal operation.
