Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The BQ79731PHPRQ1 high-voltage battery pack monitor can measure the high-voltage node of voltage division in the battery system. It can measure the voltage across the contractor and the fuse, and check the isolation voltage in the battery junction box (BJB) system. Its main specifications include:

Function: Battery monitor

Battery chemical composition: Multi-chemical

Number of batteries: 1

Fault protection: Overcurrent

Interface: SPI

Operating temperature: -40°C to 125°C

Grade: Automotive grade

Qualification: AEC-Q100

Installation type: Surface mount type

Packaging/Housing: 48-HTQFP (7x7)

In addition, the BQ79731PHPRQ1 features two integrated current detection paths and supports low-end shunt resistors. By using the coulometric counting function, precise SoC calculations can be carried out. 15 GPIO/ auxiliary inputs can be used for thermistor measurement, high-voltage measurement and driving relays. Four SW outputs can drive the MOSFET switch in the measurement path.

The BQ79731PHPRQ1 can be used as an interface and SPI HUB, capable of connecting up to eight independent SPI devices/groups. Overcurrent protection responses can be autonomously implemented through hardware pins to provide rapid protection in dangerous overcurrent events. The isolated bidirectional daisy-chain port supports transformer isolation and capacitor isolation. This device can also communicate with the MCU via UART and SPI. The typical applications of BQ79731PHPRQ1 include all-electric vehicles, plug-in hybrid vehicles and hybrid vehicles.

• 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.
