Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Allegro™ ACS71240LLCBTR-010B3 current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, automotive, commercial, and communications applications.

The device consists of a precise, low-offset linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. The resistance of the integrated conductor is far less than typical sense resistors, which reduces power loss and improves efficiency.

Features and Benefits

 • AEC-Q100 automotive qualified

 • Differential Hall sensing rejects common-mode fields

 • Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients

 • Industry-leading noise performance with greatly  improved bandwidth through proprietary amplifier and filter design techniques

 • High bandwidth 120 kHz analog output for faster response times in control applications 

• Patented integrated digital temperature compensation circuitry allows for near closed-loop accuracy over  temperature in an open-loop sensor

 • Single supply operation with nonratiometric output at  3.3 and 5 V options

 • Overcurrent FAULT available between 50% and 200% IP with 1.5 µs (typ) response time

 • Nonratiometric output provides immunity to noisy supplies

 • Small footprint QFN-12 with wettable flank and SOIC-8 suitable for space-constrained automotive applications

 • 0.6 mΩ (QFN-12) or 1.2 mΩ (SOIC-8) primary conductor resistance for low power loss and high inrush current withstand capability

 • UL certified package (SOIC-8 only) for voltage isolation

• 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.
