Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX14870ETC motor driver provides a small size, low power and easy solution for driving and controlling brushed DC motors and relays from 4.5V to 36V. Very low drive on-resistance reduces power consumption.

The driver features a charge-pump-less design to reduce external components as well as lower supply current. Integrated fast decay current regulation allows the user to adjust the peak current of the starter motor and minimises the number of external components required.

Independent input voltage sensing (SNS) reduces current detection errors caused by parasitic resistors in the alignment. the MAX14870 has pass-through protection and an internal continuity diode that absorbs motor sense current. The driver outputs are short-circuit protected against short circuits to ground, short circuits to the power supply, and short circuits from M1 to M2. FAULT outputs a low-level signal during an overheat or overcurrent fault.

The MAX14870 has PWM and direction control inputs for direction control.

The MAX14870ETC is available in a 12-pin (3mm x 3mm) TDFN-EP package and operates over the -40°C to +85°C temperature range.

• 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.
