Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20038ATIC/VY IC combines a 3.5A automotive-grade buck converter, a USB host charger adapter emulator, and a USB protection switch. for automotive USB host applications. The device family also includes a USB load current sense amplifier and a configurable feedback adjustment circuit. Configurable feedback adjustment circuitry designed to provide automatic USB voltage compensation for automotive USB host applications. Automatic USB Voltage Compensation. The integrated circuits utilise a fixed internal peak current threshold through the DC-DC converter and a user configurable external load current to limit the USB load current. The integrated circuits limit USB load current using a fixed internal peak current threshold of the converter and a user-configurable external USB load current detection amplifier threshold. The circuits provide flexible configuration options for stand-alone and monitoring applications, and can be programmed using external programming resistors and/or internal I2C registers to achieve the desired operation.

• 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.
