Product details
Overview
TLE4973A120T5S0001XUMA1 from Infineon Technologies is a high-accuracy, coreless, galvanically isolated current sensor IC for internal current rail sensing in automotive and industrial power systems. It delivers ±132 A full-scale DC/AC measurement with 220 µΩ insertion resistance, 5 V supply, and configurable differential analog output. Integrated over-current detection triggers in <1.0 µs and supports ASIL B safety compliance per ISO 26262.
For engineers reviewing the TLE4973A120T5S0001XUMA1 datasheet, TLE4973A120T5S0001XUMA1 pinout, TLE4973A120T5S0001XUMA1 application, or TLE4973A120T5S0001XUMA1 equivalent, this device is selected for high-bandwidth, low-loss current monitoring in on-board chargers, PV inverters, and smart circuit breakers where magnetic stray field immunity and end-of-line calibration capability are critical.
Technical Context
The TLE4973A120T5S0001XUMA1 employs a differential Hall plate architecture to eliminate saturation and hysteresis effects common in flux-concentrating sensors. Its integrated current rail enables direct PCB trace integration without external shunts, while temperature- and stress-compensated signal conditioning ensures stable offset and sensitivity across -40 °C to 125 °C.
Digital configuration is handled via a one-wire UART-based Digital Control Diagnostic Interface (DCDI), supporting up to 8 slaves on a single bus. The interface provides real-time temperature readout, OCD/safety status reporting, EEPROM programming, and diagnostic mode control - all without requiring additional communication hardware.

IC Role / Device Role / Timing Role: Analog current sensor feeding dual-channel sigma-delta ADCs in motor control MCU. Use Value: <1 µs OCD response enables hardware-level current limiting that bypasses software loop delay, preventing IGBT desaturation during short-circuits. |
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-130AB-T | Lower isolation (800 VVIORM), no DCDI interface, fixed 130 A FS, no EEPROM calibration | Lacks ASIL B certification and in-system programmability; suitable for non-safety-critical industrial SMPS | Select if cost-sensitive design requires basic analog output without diagnostics or safety compliance |
| TLE4972A120T5S0001XUMA1 | Same package and pinout; lower bandwidth (100 kHz), no OCD output, no DCDI, reduced temp range (-40 °C to 105 °C) | Not qualified for ASIL B; lacks over-current detection and digital diagnostics - intended for cost-optimized auxiliary rails | Select only for secondary current monitoring where functional safety and fast fault response are not required |
Compared with ACS724LLCTR-130AB-T and TLE4972A120T5S0001XUMA1, the TLE4973A120T5S0001XUMA1 uniquely combines ASIL B readiness, sub-microsecond OCD, and in-field programmability - making it the only option among the three for safety-critical, high-bandwidth, and production-calibratable applications.

FAQ
What is the maximum primary current the TLE4973A120T5S0001XUMA1 can measure continuously?
The device supports continuous measurement up to ±132 A full scale with guaranteed linearity and thermal stability. Absolute maximum ratings permit short-duration peaks of ±250 A (10 µs, 10 lifetime assertions), but sustained operation above ±132 A risks exceeding specified error bands and junction temperature limits. Derating is required above 85 °C ambient.
Can the analog output mode be changed after soldering?
Yes - output mode (semi-differential, fully-differential, or single-ended) is stored in EEPROM and can be reconfigured in-system via the DCDI interface. No hardware modification is needed; changes take effect after reset. Single-ended AOUT-only mode is prohibited per datasheet restrictions.
Does the TLE4973A120T5S0001XUMA1 require external calibration during production?
No external calibration is required: each unit ships pre-calibrated over temperature. However, end-of-line calibration is supported via DCDI to compensate for board-level thermal gradients and layout parasitics - improving system-level accuracy beyond factory specs without added test fixtures.
How is galvanic isolation achieved without a transformer or optocoupler?
Isolation is implemented using capacitive coupling between the current-sensing die and the signal-processing die inside the monolithic PG-TISON-8-6 package. This achieves 1150 VVIORM reinforced insulation and ≥1200 V partial discharge withstand, verified per IEC 60747-17, eliminating reliance on external isolation components.
