ACS716KLATR-6BB-T

Current Sensors Overview

The ACS716KLATR-6BB-T is a Hall effect-based, open-loop current sensor IC manufactured by Allegro MicroSystems. It integrates a precise, low-resistance copper conduction path with a Hall element and signal processing circuitry to provide a proportional analog voltage output for DC, AC, or dynamic current measurements. The device supports bidirectional current sensing up to 6A with a sensitivity of 100mV/A. It operates on a single 3V to 3.6V supply and features a 16-SOIC surface-mount package. Key electrical specifications include a response time of 4µs, a bandwidth of DC to 120kHz, linearity of ±0.25%, and accuracy of ±2.2%. The operating temperature range extends from -40°C to 125°C.

Current Sensors Feature Summary

• Integrates a low-resistance primary conduction path with Hall elements and signal conditioning circuitry for galvanic isolation.
• Provides a linear analog voltage output proportional to the applied magnetic field generated by the primary current.
• Features internal signal processing that includes temperature compensation and offset trimming for high precision.
• Supports bidirectional current measurement with a zero-current output at half the supply voltage.

Current Sensors Applications

• DC and AC motor control systems
• Switch-mode power supplies (SMPS)
• Load detection and management circuits

Current Sensors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required current rating and package variant. Check for RoHS compliance status and ensure the part number aligns with current design recommendations, as some variants may be marked as not recommended for new designs. Validate datasheet revisions against production requirements.

Current Sensors Selection Notes

Select this variant specifically for applications requiring a 6A bidirectional current limit. Ensure the system power supply voltage remains within the 3V to 3.6V range to maintain proper operation. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the required bandwidth up to 120kHz meets the signal frequency needs of the application.

Current Sensors Part Context

This component belongs to the ACS716 family of current sensor ICs from Allegro MicroSystems. The family utilizes integrated Hall effect technology to provide isolated current sensing solutions. The ACS716 series is designed to replace bulky traditional transformers and shunts, offering a compact surface-mount solution with high accuracy and fast response times suitable for modern electronic control units.

Current Sensors Replacement Considerations

Direct substitutes within the same family include ACS716KLATR-12CB-T for 12.5A applications and ACS716KLATR-25CB-T for 25A applications. Cross-family replacements such as the ACS712 or ACS710 series offer different current ratings and pin configurations but require schematic review. Always verify pinout compatibility and thermal characteristics when substituting.
