Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The NCV70628MW001R2G is a single-chip microstepping motor driver with position controller and control/diagnostic interface. It can be used to build specialised mechatronic solutions that are remotely linked to a LIN master node. The chip receives positioning commands over the bus and then drives the motor coil to the desired position. The on-chip position controller can be configured (OTP or RAM) for different motor types, positioning ranges, as well as speed, acceleration and deceleration parameters. the NCV70628MW001R2G acts as a slave node on the LIN bus, and the master is able to retrieve specific status information, such as the actual position, error flags, and so on, from each of the slave nodes. The integrated sensorless stall detection is able to stop the motor when it goes from running to stall. This enables noiseless but accurate position calibration during reference operation and semi-closed loop operation close to mechanical end stops. The NCV70628MW001R2G is fully compliant with the automotive voltage requirements, thanks to the I3T50 technology, which allows both high-voltage analogue circuits and digital functions to be implemented on the same chip. Thanks to this technology, the device is particularly suitable for applications with fluctuating battery power supplies.

• 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.
