Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX14917AFM has eight high-side switches that provide up to 700mA (minimum) continuous current per channel. The high-side switches have an on-resistance of 120mΩ (typical) at 25°C ambient temperature.

The device has a daisy-chainable SPI interface that supports communication with multiple MAX14917 devices using a general-purpose SPI chip select (active low CS) signal. Overload diagnostics are also provided for each channel via the SPI interface. Two watchdog timers provide an additional safety check on the host-to-slave connection.

The MAX14917AFM features a 4 x 4 LED aspect matrix that provides visual indication of channel status and overload conditions for each channel, while integrated line-to-ground and line-to-line surge protection provides tolerance to electrical stress according to IEC 61000-4-5 and requires only one TVS at VDD.The MAX14917AFM is available in a compact 48-pin 6mm x 6mm FC2QFN package.

• 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.
