The TMI8871 device is the brushed-DC motor drivers for printers, appliances, industrial equipment, and other small machines. Two logic inputs control the H-bridge 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 pulse width modulated (PWM) to control motor speed, using a choice of current-decay modes. Setting both inputs slow enter a low-power sleep mode.

The TMI8871 device does not use analog input reference voltage and current sensing resistor to regulate current limitation. TMI8871 use low power RILIM resistor to set current limit. 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 UVLO, OCP, and TSD.
