ACS720KLATR-80AB-T

Current Sensors Overview

The ACS720KLATR-80AB-T is a high-accuracy, dual-fault, galvanically isolated current sensor manufactured by Allegro MicroSystems. It utilizes open-loop Hall effect technology to measure bidirectional currents up to 80A with a sensitivity of 12.5mV/A. The device operates within a supply voltage range of 4.5V to 5.5V and features a typical response time of 4µs. It provides a bandwidth of 120kHz and maintains an accuracy of ±0.6%. The sensor is housed in a 16-SOIC wide-body package, supporting surface mount installation across a temperature range of -40°C to 125°C.

Current Sensors Feature Summary

• Galvanic isolation between the current path and electronic circuit for safety
• Dual fault detection capabilities for enhanced system monitoring
• Open-loop Hall effect sensing for precise AC/DC current measurement

Current Sensors Applications

• Motor control systems requiring precise current feedback
• Industrial power supply monitoring and protection circuits
• High-frequency inverter applications in energy conversion

Current Sensors Procurement Notes

Verify the specific suffix AB-T against the official Allegro datasheet to confirm pinout compatibility and electrical characteristics. Ensure the 16-SOIC wide-body footprint matches the target PCB layout. Confirm RoHS3 compliance status if required by project specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Current Sensors Selection Notes

Select this component when high accuracy and dual fault detection are critical for system reliability. The 80A rating suits medium-to-high current industrial applications. Consider the 16-SOIC package size for board space constraints. Verify that the 4.5V-5.5V supply range aligns with the system's available voltage rails. Evaluate the 120kHz bandwidth against the switching frequency of the controlled load.

Current Sensors Part Context

This part belongs to the ACS720 series of current sensors, designed for applications demanding high precision and isolation. Unlike standard Hall sensors, the ACS720 integrates dual fault outputs to indicate over-current or short-circuit conditions. The series offers various current ratings within the same package form factor, allowing for design flexibility while maintaining consistent interface characteristics.

Current Sensors Replacement Considerations

Direct substitutes include other ACS720 variants such as ACS720KLATR-65AB-T or ACS720KLATR-15AB-T, provided the current rating difference is acceptable. Verify that any replacement maintains the same 16-SOIC package and pin configuration. Check datasheets for changes in sensitivity or accuracy specifications.
