Current Sensors Procurement Notes

Verify the specific suffix 'HSN850MR' against official datasheets to confirm bidirectional functionality and package dimensions. Ensure compatibility with 4.75V-5.5V supply rails and check thermal requirements for the -40°C to 125°C operating range. Confirm RoHS3 compliance status during sourcing.

Current Sensors Selection Notes

Select this component for applications requiring bidirectional current measurement up to 50A. Consider the 80mV/A sensitivity and 1MHz bandwidth for dynamic load monitoring. The 8-SOIC package suits space-constrained designs. Verify that the ±1% accuracy meets system tolerance requirements compared to unidirectional alternatives.

Current Sensors Part Context

Part of the XtremeSense™ Crocus series, leveraging TMR technology for enhanced signal integrity. This model specifically addresses bidirectional sensing needs, differing from unidirectional variants like the CT418 or CT428 series which lack reverse current capability.

Current Sensors Replacement Considerations

For unidirectional applications only, the CT418-HSN850DR or CT428-HSN850DR may serve as substitutes. Note that these replacements lack bidirectional functionality. Direct replacement requires verifying if bidirectional sensing is strictly necessary for the circuit topology.
