Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Broadcom® ACHS-7123 product family is a family of fully integrated, Hall-effect based, isolated, linear current sensor devices designed for AC or DC current detection in industrial, commercial, and communications systems. Each ACHS-7123-000E device consists of a precision, low offset, linear Hall circuit with a copper conduction path located near the chip surface. The applied current flowing through the copper conduction path creates a magnetic field, which the Hall IC converts to a proportional voltage. The accuracy of the device is optimised because the magnetic signal is very close to the Hall sensor.

Precisely proportional voltages are provided by a low offset, chopper-stabilised CMOS Hall integrated circuit, which is programmed after packaging to ensure accuracy. The output of the device has a positive slope (>VOUT(Q)) as increasing current flows through the primary copper conduction path (from pins 1 and 2 to pins 3 and 4), which is used for current sampling.

The conductive path has a typical internal resistance of 0.7 mΩ and low power loss. The termination of the conductive path is electrically isolated from the signal leads (pins 5 to 8). These features are available in a compact, surface-mount SO-8 package that meets worldwide safety regulatory standards.

• 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.
