Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The BQ76PL536ATPAPRQ1 device is a stackable battery monitor and protector for three to six series-connected lithium-ion batteries.The BQ76PL536ATPAPRQ1 integrates an analogue front-end (AFE) and a precision analogue-to-digital converter (ADC) to accurately measure battery voltage. A separate ADC is used to measure temperature.

In addition to measuring temperature, the device provides overvoltage and undervoltage monitoring protection for each channel. User-programmable protection thresholds and delay times are stored via non-volatile memory. Once one of these thresholds is exceeded, a fault signal is output.

Support for a 192-cell battery pack can be achieved by stacking the BQ76PL536ATPAPRQ1 devices.

• 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.
