CT416-HSN820DR

Current Sensors Overview

The CT416-HSN820DR is a unidirectional, magnetoresistive current sensor from Allegro MicroSystems' XtremeSense Crocus series. It measures AC/DC currents up to 20A with a sensitivity of 100mV/A and a total error output of ±1.0% FS. The device features a linear analog voltage output, operates on a 3V to 3.6V supply, and draws a maximum supply current of 9mA. It offers a bandwidth of DC to 1MHz and a response time of 300ns. Packaged in an 8-SOIC (0.154" width) surface-mount case, it functions within a temperature range of -40°C to 125°C.

Current Sensors Feature Summary

• Supports wide bandwidth from DC to 1MHz

Current Sensors Applications

• Motor control systems
• Power supply monitoring
• Industrial automation equipment

Current Sensors Procurement Notes

Verify the specific suffix DR indicates tape-and-reel packaging configuration. Confirm RoHS3 compliance status prior to integration. Check MSL level 3 handling requirements during assembly. Ensure supply voltage remains within 3V to 3.6V limits. Validate thermal resistance specifications for the SOIC-8 package under expected operating conditions.

Current Sensors Selection Notes

Select this component for applications requiring precise measurement of low to medium current levels up to 20A. The 100mV/A sensitivity provides adequate resolution for detailed circuit analysis. The 1MHz bandwidth supports high-frequency switching environments. Consider the unidirectional nature if bidirectional sensing is not required. The SOIC-8 package facilitates standard surface-mount assembly processes.

Current Sensors Part Context

This part belongs to the CT416 series of XtremeSense TMR sensors. It shares the same 8-SOIC footprint and general interface characteristics as other variants in the family, such as the CT416-HSN830DR. Differences primarily lie in current rating and sensitivity parameters. The series utilizes advanced tunnel magnetoresistance technology for enhanced performance.

Current Sensors Replacement Considerations

CT416-HSN830DR offers a higher current rating of 30A with different sensitivity. CT418-HSN850DR is a distinct series variant with different supply voltage requirements. Verify pin compatibility and electrical parameter alignment before substitution.
