For engineers reviewing the TLE4973R025T5S0001XUMA1 datasheet, TLE4973R025T5S0001XUMA1 pinout, TLE4973R025T5S0001XUMA1 application, or TLE4973R025T5S0001XUMA1 equivalent, key selection criteria include ASIL B safety compliance, <1.0 µs over-current detection latency, ±0.5% total error over temperature, ratiometric output configurability, and DCDI one-wire diagnostic interface support.
Technical Context
The TLE4973R025T5S0001XUMA1 implements a differential Hall plate architecture with on-chip temperature and stress compensation, eliminating saturation and hysteresis effects inherent in open-loop flux-concentrating sensors. Its functional isolation (1150 VVIORM) and partial discharge rating (≥1200 V) enable direct integration into high-voltage internal current rails.
It features a configurable analog output (semi-differential mode by default), programmable OCD threshold via embedded EEPROM, and a Digital Control Diagnostic Interface (DCDI) supporting auto-addressing for multi-sensor bus configurations - all operating within AEC-Q100 Grade 1 ambient temperature range (−40 °C to +125 °C).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar coreless current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACS724LLCTR-20AU-T | Lower isolation (800 VVIORM), fixed 20 A FS, no DCDI interface, no EEPROM programmability | Limited to non-ASIL designs; lacks in-system calibration and OCD configuration flexibility | Select when cost-sensitive, non-automotive, and fixed-range operation suffices |
| TLE4972R025T5S0001XUMA1 | Single-ended output only; no semi-/fully-differential modes; identical package, pinout, and isolation rating | Requires external differential receiver for noise immunity; less flexible for mixed-signal PCB routing | Select only if system already uses single-ended ADC inputs and board space prohibits differential trace routing |
Compared with ACS724LLCTR-20AU-T and TLE4972R025T5S0001XUMA1, the TLE4973R025T5S0001XUMA1 uniquely combines ASIL B compliance, field-programmable OCD thresholds, differential output flexibility, and 1150 V isolation - making it the only choice for safety-critical, high-density automotive power modules requiring adaptive protection and precision metrology.

FAQ
What is the maximum continuous primary current the TLE4973R025T5S0001XUMA1 can measure without derating?
The device is rated for ±27 A full-scale linear range, with absolute maximum primary current of ±70 A RMS (high-frequency) or ±70 A peak (low-frequency, <10 Hz). Continuous operation at ±27 A is thermally sustainable on standard 2 oz copper PCBs per Infineon's reference layout; sustained currents above ±40 A require thermal modeling and enhanced copper pour.
Does the TLE4973R025T5S0001XUMA1 require external calibration after soldering?
No external calibration is required: the device ships pre-calibrated over temperature (−40 °C to +125 °C) with factory-trimmed offset, gain, and linearity. End-of-line calibration via DCDI is optional and only needed if system-level accuracy tighter than ±0.5% total error is mandated - e.g., revenue-grade energy metering in EVSE applications.
Can the OCD threshold be adjusted dynamically during runtime?
Yes - the OCD threshold is stored in EEPROM and can be reprogrammed in-system via the DCDI interface at any time, including during operation. Threshold updates take <100 µs and do not interrupt analog output or measurement continuity; the new value becomes active on the next current cycle after write confirmation.
Is the TLE4973R025T5S0001XUMA1 pin-compatible with other TLE4973 variants?
Yes - all TLE4973 variants (R120/A120/R075/A075/R050/A050/R025/A025) share identical PG-TISON-8-6 package, pinout, and footprint. Only full-scale range, default OCD threshold, and ratiometricity setting differ; these are configured in EEPROM and can be modified post-soldering, enabling hardware reuse across power levels.
