Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DRV8871DDARQ1 device is a brush-type DC motor driver for printers, appliances, industrial equipment, and other small machines. Two logic inputs control the H-bridge driver, which consists of four N-channel metal-oxide-semiconductor field-effect transistors (MOSFETs) capable of bi-directionally controlling the motor at peak currents up to 3.6A. Motor speed can be controlled by pulse-width modulation (PWM) of the inputs using a current-decay mode. If both inputs are set low, the motor driver enters a low-power sleep mode.

The DRV8871DDARQ1 devices feature advanced current regulation circuitry that does not use an analogue voltage reference or external sense resistors. This new solution uses standard low-cost, low-power resistors to set the current threshold. The device's ability to limit current to a known level significantly reduces system power requirements and eliminates the need for large capacitors to maintain a stable voltage, especially during motor startup and stall.

The device provides comprehensive protection against faults and short-circuit problems, including under-voltage lockout (UVLO), over-current protection (OCP) and thermal protection (TSD). The device will automatically return to normal operation after the fault is removed.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
