Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ARG82801KLVATR is a power management IC with an integrated buck or buck/boost preconditioner, four LDOs and four floating gate drivers. The preconditioner uses a buck or buck/boost topology to efficiently convert the automotive battery voltage into a tightly regulated intermediate voltage with control, diagnostic and protection functions.

The outputs of the preconditioner are powered by a 350 mA linear regulator with 3.3 V or 5.0 V selectable, a 5 V/115 mA linear regulator and two 120 mA protection linear regulators tracking the VUC output. designed to power microprocessors, sensors and CAN transceivers, the ARG82801 is ideal for under-the-hood applications.

• 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?
