Current Sensors Procurement Notes

Verify the specific suffix E0001 against official Infineon documentation to confirm the exact variant configuration. Ensure compatibility with the required operating temperature range and supply voltage specifications before integration. Confirm that the 8-PowerTDFN package dimensions align with the target PCB layout and thermal requirements. Cross-reference the AEC-Q100 certification status if automotive compliance is mandatory for the end application.

Current Sensors Selection Notes

Select this component when unidirectional current measurement up to 25A is required with high precision. The open-loop architecture offers a balance between cost and performance for general-purpose sensing. Consider the 250ns response time for applications requiring fast transient detection. Evaluate the ±3.45% accuracy against system tolerance requirements. The single-channel design simplifies circuit topology compared to multi-sensor solutions.

Current Sensors Part Context

This part belongs to the XENSIV™ TLI4971 family of magnetic current sensors. It represents the unidirectional variant within the series, distinguished from bidirectional models like the TLE4971. The TLI4971 series focuses on consumer and industrial applications where cost-effective, high-precision current sensing is essential. It complements other Infineon power management and gate driver components in complete system designs.

Current Sensors Replacement Considerations

TLE4971A025T5UE0001XUMA1 is documented as a parameter-equivalent alternative. Verify bidirectional capability requirements, as the replacement supports reverse current flow unlike the unidirectional TLI4971 variant.
