ACS724LMATR-50AU-T

Current Sensors Overview

The ACS724LMATR-50AU-T is a board-mount current sensor manufactured by Allegro MicroSystems. It utilizes Hall effect technology with differential sensing for bidirectional current measurement up to 50A. The device features a ratiometric voltage output and operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a sensitivity of 80mV/A, a response time of 4µs, and a frequency range of DC to 120kHz. It offers ±1.5% accuracy and linearity, drawing a maximum supply current of 14mA. The component is housed in a 16-SOIC package and supports an operating temperature range of -20°C to 85°C.

Current Sensors Feature Summary

• Differential Hall effect sensing provides common-mode field rejection capabilities to minimize interference from external magnetic fields.
• Integrated current-carrying loop enables galvanic isolation between the power path and the signal output.
• Ratiometric analog voltage output scales directly with the supply voltage, simplifying interface with microcontrollers.

Current Sensors Applications

• Motor control systems requiring precise bidirectional current monitoring
• Power supply overcurrent protection circuits
• Industrial automation equipment load sensing

Current Sensors Procurement Notes

Verify that the specific suffix AU-T corresponds to the required automotive grade qualification and AEC-Q100 certification. Confirm the 16-SOIC package dimensions match the PCB footprint design. Ensure the supply voltage range aligns with the system's logic levels. Check RoHS3 compliance status if environmental regulations apply. Validate the sensitivity value against the application's signal processing requirements.

Current Sensors Selection Notes

Select this component when high accuracy and fast response are critical for bidirectional current sensing. The differential architecture is suitable for noisy environments where common-mode interference must be rejected. Consider the 16-SOIC package size for space-constrained designs. The ratiometric output is ideal for systems using varying supply voltages without needing additional reference components.

Current Sensors Part Context

This part belongs to the ACS724 series of integrated current sensors. The series includes variants with different current ratings and packages, such as the ACS724LLCTR for smaller form factors. The LMATR suffix indicates a specific tape-and-reel packaging configuration optimized for automated surface-mount assembly processes.

Current Sensors Replacement Considerations

Direct substitutes within the same family include ACS724LMATR-30AU-T for lower current applications. Other variants like ACS724KMATR-65AB-T offer different accuracy or temperature specifications. Verify pinout compatibility and thermal characteristics before substitution.
