Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Allegro™ ACS773LCB-100B-PFF-T current sensor IC provides an economical and accurate solution for AC or DC current sensing, ideal for motor control, load sensing and management, power supply and DC-DC converter control, and inverter control. 2.5µs response time enables overcurrent fault detection in safety critical applications

The device consists of a precision, low-offset linear Hall circuit with a copper conduction path located near the chip. The applied current flowing through this copper conduction path generates a magnetic field, which the Hall IC converts into a proportional voltage. The accuracy of the device is optimised by the proximity of the magnetic signal to the Hall sensor. An accurate proportional output voltage is provided by a low offset, chopper-stabilised BiCMOS Hall IC which is factory programmed to guarantee accuracy. A patented digital temperature compensation technique greatly improves the accuracy and temperature stability of the IC.

• 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.
