CS1505B

Current Sensors Overview

The CS1505B is a unipolar open-loop current sensor module manufactured by Same Sky. It features a single channel with a detection current of 5A and operates within a frequency range of DC to 40kHz. The device provides a voltage ratio output and requires a supply voltage of 4.75V to 5.25V, drawing a maximum supply current of 25mA. Key performance specifications include a linearity of ±0.5% and an accuracy of ±4.9%. The response time is specified at 7µs, and the unit supports through-hole installation in a module package.

Current Sensors Feature Summary

• Open-loop magnetic sensing technology for non-intrusive current measurement
• Unipolar operation designed for positive current direction monitoring
• Voltage ratio output interface compatible with standard analog processing

Current Sensors Applications

• Power supply circuit protection and monitoring
• Battery management systems requiring unipolar current tracking
• Industrial motor drive control loops

Current Sensors Procurement Notes

Verify the specific suffix against official documentation to confirm pinout configuration and tolerance class. Ensure the selected variant matches the required supply voltage range and thermal operating conditions for the target application environment before finalizing procurement orders.

Current Sensors Selection Notes

Select this component when unipolar current monitoring is required rather than bidirectional sensing. Compare the ±4.9% accuracy specification against system requirements to ensure sufficient precision for the intended load monitoring application without unnecessary cost overhead.

Current Sensors Part Context

This part belongs to the CSXX05 series of open-loop current sensors from Same Sky. It shares architectural similarities with other models in the family but is distinguished by its 5A detection limit and unipolar polarity designation. The module format facilitates direct integration into printed circuit board assemblies.

Current Sensors Replacement Considerations

Cross-reference with CS1005U for higher current capacity or CS15120B for bidirectional capability. Verify that substitute parts maintain compatibility with the existing supply voltage constraints and physical mounting dimensions.
