CT428-HSN865MR

Current Sensors Overview

The CT428-HSN865MR is a unidirectional current sensor utilizing XtremeSense™ TMR technology. It features a 65A peak detection range with a sensitivity of 61.5mV/A and operates on a 5.0V supply voltage. The device offers high precision with ±0.7% accuracy and ±0.2% linearity, supporting frequencies up to 1MHz. It includes a fast transient pulse (FLTP) pin for noise immunity and operates within a temperature range of -40°C to +125°C in an 8-lead SOIC package.

Current Sensors Feature Summary

• Utilizes XtremeSense™ TMR technology for low-noise performance
• Includes FLTP pin for enhanced noise immunity
• Provides high accuracy and linearity specifications

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify the specific suffix MR against datasheet requirements to ensure correct packaging and lead time alignment. Confirm that the unidirectional configuration matches the application's current flow direction. Check for RoHS3 compliance status if environmental regulations apply. Validate the 8-SOIC footprint compatibility during PCB layout finalization.

Current Sensors Selection Notes

Select this component when bidirectional sensing is not required and a 65A peak limit suffices. The 5.0V supply requirement distinguishes it from lower voltage variants like the CT416 series. Consider the FLTP feature if the environment contains significant electromagnetic interference. Ensure the thermal management supports the +125°C operating limit.

Current Sensors Part Context

This part belongs to the Allegro MicroSystems XtremeSense™ Crocus series, leveraging Tunnel Magnetoresistance (TMR) technology. It represents a modern alternative to traditional Hall-effect sensors, offering improved signal-to-noise ratios and higher precision for demanding current sensing applications in automotive and industrial sectors.

Current Sensors Replacement Considerations

Public confirmed substitutes include CT428-HSN865DR for tape-and-reel packaging variations. Cross-reference with CT416 or CT426 series only if voltage supply constraints differ significantly.
