ACS716KLATR-25CB-T

Current Sensors Overview

The ACS716KLATR-25CB-T is a Hall effect-based, open-loop current sensor manufactured by Allegro MicroSystems. It provides bidirectional current sensing with a rated detection current of 25A and a sensitivity of 18.5mV/A. The device features a ratiometric voltage output and operates within a supply voltage range of 3V to 3.6V. Key electrical parameters include a maximum supply current of 11mA, a response time of 4µs, and a frequency bandwidth from DC to 120kHz. Accuracy is specified at ±2.9% with linearity of ±0.25%. It is housed in a 16-SOIC package (7.50mm width) and supports an operating temperature range of -40°C to 125°C.

Current Sensors Feature Summary

• Utilizes integrated Hall effect technology for galvanic isolation between the current-carrying conductor and the signal output circuitry.

Current Sensors Applications

• AC/DC motor control systems
• Switched-mode power supplies (SMPS)
• Industrial process controls

Current Sensors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the received part matches the specific suffix designations for packaging and lead-frame configuration. Check for recent Product Change Notifications regarding packaging updates or material substitutions. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering processes.

Current Sensors Selection Notes

Select this component when a low-cost, open-loop solution is required for currents up to 25A. The 18.5mV/A sensitivity offers lower resolution compared to higher-sensitivity variants but may suit applications where offset calibration is manageable. Consider the narrow 3V-3.6V supply voltage constraint during system power rail design. Evaluate thermal management needs as the device dissipates heat based on internal resistance and load current.

Current Sensors Part Context

This part belongs to the ACS716 family of current sensor ICs. It is distinct from the ACS710 series, which typically supports a wider 3V-5.5V supply range and different sensitivity profiles. The 'K' suffix indicates a specific lead-frame configuration, while 'TR' denotes tape-and-reel packaging. This model represents a mature product line with established integration into various industrial and consumer electronics designs.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Allegro MicroSystems replacement guides or engineering change notices for valid cross-reference options.
