Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ACS70331EOLCTR-2P5B3 is Allegro’s first integrated, high sensitivity, current sensor IC for <5 A current sensing applications. It incorporates giant magneto-resistive (GMR) technology that is 25 times more sensitive than traditional Hall-effect sensors to sense the magnetic field generated by the current flowing through the low resistance, integrated primary conductor. 

 The analog output provides a low noise high-speed signal, which is proportional to the current flowing through the primary. The response time of the part is typically 535 ns. The ACS70331 is offered in four factory-programmed sensitivity and offset levels to optimize performance over the desired current measurement range. 

The differential configuration of the GMR elements, relative to the integrated current conductor, provides significant rejection of stray magnetic fields, resulting in stable operation even in magnetically noisy environments. 

The ACS70331EOLCTR-2P5B3 operates from a single 3.3 V power supply and is qualified over the full commercial temperature range of –40°C to 85°C. It is offered in a low-profile, space-saving surface mount QFN-12 and SOIC-8 packages.

Features And Benefits

• High sensitivity current sensor IC for sensing up to 5 A (DC or AC)

• 1 MHz bandwidth with response time <550 ns

• Low noise: 8 mA(rms) at 1 MHz

• Non-ratiometric, analog output proportional to AC and DC current

• Single 3.3 V supply operation

• High DC PSRR enables use with low accuracy power supplies or batteries (3 to 4.5 V operation)

• 1.1 mΩ primary conductor resistance results in low power loss

• Small surface mount QFN-12 and SOIC-8 packages for space-constrained applications

• 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.
