Description

Overview

Allegrom's ACS712ELCTR-20A-T offers accurate and affordable solutions for AC and DC current sensing in a range of systems.Applications such as motor control, load detection, switch-mode power supplies, and overcurrent fault protection can be easily implemented with it. Recall that it is not intended for use in automobiles. Its interior contains a precisely designed Hall circuit and a copper channel that converts current to voltage close to the surface. Because of the proximity of the Hall sensor to the magnetic field in this arrangement, it is accurate.

Enhanced Accuracy

Enhanced accuracy comes from the magnetic signal being close to the Hall transducer. When current flows through the main copper line (from pins 1 and 2 to pins 3 and 4), used for sampling, the output voltage goes up (>VOUT(Q)). This path has low resistance (about 1.2 mΩ), so there's little power loss. Also, the device can handle up to five times the normal current because of the thick copper conductor. Importantly, for applications needing electrical isolation, there's no need for expensive methods like opto-isolators because the terminals of the copper channel are separate from the signal leads (pins 5 through 8).

Compact Design and Construction

Compact Design_ACS712ELCTR This product is conveniently integrated into circuit boards thanks to its tiny SOIC8 packaging. Additionally, its matte tin-coated leadframe makes it appropriate for lead-free assembly procedures.Some high-temperature solder balls are currently exempt from RoHS restrictions, despite the majority of the device being Pb-free. Every unit is calibrated before it is shipped from the factory.

FAQ

Q: What is the ACS712ELCTR-20A-T's sensitivity?

A: This model's sensitivity is 100 millivolts per ampere (A), which means that the output voltage rises by 100 millivolts for each ampere of current flowing through the device.

Q: What is the ACS712ELCTR-20A-T's working temperature range?

A: It is suited for use in a wide range of climatic situations because it can function within a temperature range of -40°C to 85°C.

Q: How quickly does the ACS712ELCTR-20A-T respond?

A: With a response time of under 5 microseconds (µs), it can promptly identify and react to variations in current flow, guaranteeing precise and timely readings.

Q: What is the purpose of the ACS712ELCTR-20A-T?

A: It is employed in many different applications, including motor control, load detection, and overcurrent protection in commercial and industrial systems, to measure both AC and DC currents.

Q: What is the ACS712ELCTR-20A-T's accuracy?

A: This product offers high accuracy due to its precise Hall circuit and close proximity of the magnetic field to the Hall sensor, ensuring reliable current measurements.

Q: Can overcurrent scenarios be handled by the ACS712ELCTR-20A-T?

A: Yes, it is appropriate for applications with sporadic overcurrent conditions because it is built to tolerate up to five times the typical current.

Q: Is it possible to achieve electrical isolation with the ACS712ELCTR-20A-T?

A: Indeed, the conductive path's terminals and signal leads are electrically separated, making it suitable for use in applications that need electrical isolation without the need for further parts.

Q: What packaging is included with the ACS712ELCTR-20A-T?

A: It comes in a tiny SOIC8 package that can be assembled using common lead-free printed circuit board construction techniques.

Q: Is there any environmental regulation that the ACS712ELCTR-20A-T breaks?

A: Internally, this model is primarily lead-free and compliant with RoHS standards; the flip-chip high-temperature Pb-based solder balls are currently exempt. To assure accuracy, every product is fully calibrated before shipping.
