This LCT module was developed by Allegro Microsystems, Inc., which is an American company that designs, develops, and manufactures semiconductor products.

Application Field

The ACS722LLCTR-10AU-T can be used to measure the AC/DC current in a variety of applications related to solar energy, wind power, welding, and laboratory testing. It can be used to monitor the current flow in solar systems as they generate power from sunlight and in wind turbines as they rotate to generate electricity. Additionally, the ACS722LLCTR-10AU-T can be used in welding applications to measure the electric current running through the welders. Furthermore, this LCT can also be used to monitor the current flow in laboratory tests and experiments.

Working Principle

The ACS722LLCTR-10AU-T uses a linear current transducer (LCT) design to measure the AC/DC current in the application. An LCT consists of a ferrite core that surrounds a wire coil, which carries the current to be measured. The magnetic flux generated by the current passing through the wire coil generates a voltage across the coil, which is measured by the LCT module. This measured voltage is proportional to the current flowing through the coil, and the exact amount of current is determined by the resistor in the module. The module also includes an integrated amplifier circuit that amplifies the measured voltage using a chopper stabilization technique that ensures accuracy.

In addition, the ACS722LLCTR-10AU-T module has a variety of features that help to protect the module from various factors such as over-voltage, over-current, EMC interference, and ESD protection. The module also has an integrated temperature monitoring circuit to ensure that the temperature of the LCT does not exceed the threshold. Finally, the module can be used with a range of microcontrollers with SPI or I2C communication interfaces for easy integration.

Conclusion

The ACS722LLCTR-10AU-T is a low-resistance linear current transducer (LCT) ideal for monitoring the AC/DC current in solar, wind, welding, and laboratory applications. It uses an LCT design in combination with an integrated amplifier circuit to accurately measure the voltage across the coil. Additionally, the module has a variety of features such as over-voltage, over-current, EMC interference, ESD protection, and temperature monitoring. Finally, the module is compatible with a range of microcontrollers with SPI or I2C communication interfaces for easy integration.
