ACS716KLATR-12CB-NL-T

Current Sensors Overview

The Allegro MicroSystems ACS716KLATR-12CB-NL-T is a Hall effect-based current sensor IC designed for AC and DC current measurement. It features a 12.5A detection range with a sensitivity of 37mV/A and a ratiometric voltage output. The device operates on a 3V to 3.6V supply, drawing a maximum of 11mA. It offers a bandwidth of DC to 120kHz, a response time of 4µs, and an accuracy of ±2.7% with linearity of ±0.25%. Packaged in a 16-SOIC surface-mount case, it supports bidirectional sensing within an operating temperature range of -40°C to 125°C.

Current Sensors Feature Summary

• Integrates a precision linear Hall sensor with a low-resistance copper conduction path for high-voltage isolation.
• Provides a ratiometric analog voltage output that linearly tracks the magnetic field generated by the primary current.
• Utilizes proprietary integrated shielding technology to ensure high immunity against DV/DT and stray electric fields.
• Features factory-trimmed sensitivity and quiescent output voltage for precise performance without external calibration.

Current Sensors Applications

• General-purpose current sensing in industrial and commercial systems
• DC motor control and commutation circuits
• Overcurrent protection and load switch management
• Switch-mode power supplies (SMPS) and battery charger monitoring

Current Sensors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check for RoHS compliance status and recent Production Change Notices regarding packaging updates. Ensure the source documentation aligns with the official Allegro MicroSystems datasheet for accurate electrical parameters.

Current Sensors Selection Notes

Select this component for applications requiring galvanic isolation between the primary current path and the control circuitry. The 12.5A rating suits moderate current loads where low insertion loss is critical due to the 1mΩ conductor resistance. Consider the 16-SOIC package for surface-mount assembly constraints. Evaluate the 120kHz bandwidth against signal noise requirements and the need for filtering capacitors on the filter pin to optimize resolution for lower frequency applications.

Current Sensors Part Context

This part belongs to the ACS716 series of current sensor ICs from Allegro MicroSystems. It is distinct from the ACS710 series, which typically includes integrated overcurrent detection outputs. The ACS716 focuses on providing a pure analog ratiometric output proportional to the sensed current, making it suitable for continuous monitoring rather than simple fault triggering.

Current Sensors Replacement Considerations

Check for availability as the part status may be listed as not recommended for new designs. Verify if alternative suffixes within the ACS716 family offer identical electrical characteristics but different packaging options. Cross-reference with other Allegro Hall-effect sensors if the specific 12.5A rating or 16-SOIC footprint requires adaptation.
