Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DRV8899QWRGERQ1 is a fully integrated stepper motor driver that supports up to 1A full-scale current with internal microstepping indexer, smart tuned attenuation technology, advanced stall detection algorithms and integrated current sensing. Featuring a simple step/direction control interface to manage direction and step rate, it supports up to 1/256 levels of microstepping for smooth motion trajectories. The integrated current sensing feature eliminates the need for two external resistors, saving board space and cost.The DRV8899QWRGERQ1 offers eight attenuation mode options including: Smart Tuning, Slow, and Hybrid attenuation options. Smart tuning technology automatically adjusts for optimal current regulation performance and compensates for any motor variations and aging effects. The device also includes an integrated torque DAC that allows the controller to adjust the output current via SPI without adjusting the VREF voltage reference. The device features an nSLEEP pin that provides a low power sleep mode for very low standby current. The device features full-duplex, 4-wire synchronous SPI communications and allows up to 63 devices to be daisy-chained for configurability and detailed fault reporting.

• 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.
