Current Sensors Overview

The TLE4971A025N5E0001XUMA1 is a high-precision coreless current sensor from Infineon’s XENSIV family, designed for automotive and industrial applications. It features an analog voltage output and dual fast overcurrent detection (OCD) outputs. The device supports bidirectional current measurement up to 25A with a supply voltage range of 3.1V to 3.5V. It operates within a temperature range of -40°C to 125°C and is housed in an 8-PowerTDFN package. The sensor includes internal diagnostics for open wire and short circuit conditions.

Current Sensors Feature Summary

• Coreless magnetic sensing technology ensures high precision and linearity without the saturation risks associated with traditional iron-core sensors.
• Integrated dual fast overcurrent detection (OCD) outputs provide immediate protection signals for power stage control.
• Comprehensive on-chip self-diagnostics monitor open wire, short circuit, and supply voltage anomalies to enhance system safety.
• Analog interface allows direct connection to microcontrollers or ADCs, simplifying signal processing requirements.

Current Sensors Applications

• Automotive motor control systems including electric vehicle traction inverters and auxiliary drives
• Industrial servo drives and variable frequency drive current monitoring
• On-board charger (OBC) and DC-DC converter current sensing in electrified vehicles
• High-reliability industrial power supply overcurrent protection circuits

Current Sensors Procurement Notes

Verify that the ordering suffix matches the required sensitivity and package variant, as the TLE4971 series offers multiple configurations. Confirm AEC-Q100 qualification status if deploying in automotive environments. Check moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure supply voltage constraints (3.1V–3.5V) align with system power rails. Review official datasheets for specific OCD threshold programming options.

Current Sensors Selection Notes

Select this component when bidirectional current sensing up to 25A is required with high accuracy. The analog output suits applications needing continuous current feedback rather than digital interfaces. Consider the 8-PowerTDFN package for surface-mount thermal management. Evaluate the dual OCD outputs for simplified hardware protection schemes compared to software-based detection methods.
