Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LV8907UWR2G is a high-performance, sensorless, three-phase BLDC motor controller with an integrated gate driver for driving external N-MOSFETs.An on-chip, two-stage charge pump provides the required gate current for a wide range of external N-MOSFETs of the ultra-low RDS(ON) type.The device provides a wide range of system protection and diagnostic features such as overcurrent, overvoltage, short-circuit, undervoltage, and high temperature. overcurrent, overvoltage, short circuit, undervoltage, and high temperature. It supports open-loop as well as closed-loop speed control with user-configurable startup, speed settings, and proportional/integral (PI) control coefficients, making it suitable for a wide range of motor and load combinations.The LV8907 has a built-in linear regulator for powering external circuits, supervisory timers, and Local Area Network (LIN) transceivers, providing the smallest possible footprint for a system solution. An SPI interface is provided for parameter setting and system status monitoring, and the LV8907 operates with a junction temperature tolerance up to 175°C and has electronically compatible LIN control signals (PWM and Enable), making it an ideal standalone automotive BLDC motor control system solution.

• 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.
