Current Transducers

Current transducers are critical components used to measure and provide feedback of the amount of electric current that flows through a device or circuit. ACS713ELCTR-20A-T is a form of transducers that is especially useful for measuring high currents. It is an ergonomic, monolithic integrated circuit and holds the HSOP-8 package for the current sensing element. This article will explore the applications of the ACS713ELCTR-20A-T as well as the working principle and operation of this chip.

Applications

ACS713ELCTR-20A-T offers high integration and is packaged in a compact. It is important for applications that need to measure the short-duration currents with a very low-power design. It is widely used in power supplies, electric vehicles, and solar-power systems. This chip is mainly used in applications that require steady output readings, such as current shunt monitoring, cycle-by-cycle current sensing, and overload protection. It can also be used in the power-processing control loops of motor drives, be it AC or DC motors, and is suitable as a low-power current switch.

Working Principle

The working principle of the ACS713ELCTR-20A-T lies in its ability to detect and measure a low-sensitivity, low-current, and low-voltage signal in a low-power setting. This chip converts the mechanically-measured input current into a proportional output voltage and takes advantage of the Hall Effect principles. This magnetic sensing technology utilizes the current in an external coil to generate a proportional output voltage which reinforces and provides a very precise measure of current.

Essentially, the current flow in the external coil creates a magnetic field that is detected by a Hall element which lies inside the chip. This in turn is responsible for the generation of the Hall voltage. The Hall voltage in turn is further amplified and converted into the corresponding output voltage. The Hall voltage generated is then buffered and conditioned and after that it is linearly proportional to the original current flow.

Therefore, the output response of the ACS713ELCTR-20A-T is linear and the gain of the circuit can be varied using external resistor networks. Output sensitivity is determined by the value of the external resistor used. This chip is also equipped with two additional signal pins that can be used to minimize noise gain and provide a fast response time of the output.

Operation

The chip\'s output is determined by the output current, the sensitivity of the chip, and the resistance of the external resistor network. With that said, the ACS713ELCTR-20A-T is capable of operating in temperatures of between -40 to 125 degrees Celsius and sustain a maximum supply voltage of no more than 26V. When the supply voltage exceeds the maximum input voltage threshold, the output of the chip will be inversely proportional to the specified supply voltage. In terms of frequency response, the device is capable of outputting a frequency response from 0Hz up to 5MHz.

The ACS713ELCTR-20A-T contains an internal 0.02 ohm shunt resistor, so the input current is not limited. The chip has an observed current resolution of 22.5uA and is capable of measuring bothAC and DC current. This chip has a two-wire design, so it does not require any external power for operation, making it quite suitable for applications in space-restricted areas.

Conclusion

In conclusion, the ACS713ELCTR-20A-T is a versatile current transducers consisting of individual elements of high integration that can be used to measure low-level currents. This chip can be used for many applications where steady operation and low-power consumption is essential. It is suitable for use in motor control, overload protection, and current measurement in power supplies, electric vehicles, and solar-power systems. It functions by taking advantage of the magnetic sensing technology, in which the external coil generates a Hall voltage, which is then amplified into the desired output voltage.
