Product details

Overview

TLE4973R075T5S0001XUMA1 from Infineon Technologies is a high-accuracy, coreless magnetic current sensor with ±82 A full-scale range, 5 V supply, and configurable differential analog output. It integrates a low-loss (220 µΩ) current rail, supports ASIL B safety compliance per ISO 26262, and delivers fast over-current detection (<1.0 µs). Used in on-board chargers and PV inverters for precise DC/AC rail current monitoring.

For engineers reviewing the TLE4973R075T5S0001XUMA1 datasheet, TLE4973R075T5S0001XUMA1 pinout, TLE4973R075T5S0001XUMA1 application, or TLE4973R075T5S0001XUMA1 equivalent, this page provides verified functional specifications, real-world use cases, validated alternatives, and supply-ready procurement details - all grounded in Infineon's official documentation and AEC-Q100 Grade 1 qualification.

Technical Context

The TLE4973R075T5S0001XUMA1 employs a differential Hall plate architecture to eliminate saturation and hysteresis, enabling linear sensing across ±82 A with <±0.5% total error over -40°C to +125°C. Its integrated current rail and galvanic isolation (1150 V_VIORM) support direct placement on high-power internal rails without magnetic concentrators.

It features a one-wire Digital Control Diagnostic Interface (DCDI) for in-system EEPROM programming of OCD thresholds and sensitivity, plus real-time readout of temperature, safety status, and diagnostic mode control. The device operates in semi-differential output mode by default and supports auto-addressing for multi-sensor bus configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Full-Scale Range	±82 A - defines maximum measurable bidirectional current before clipping; enables use in 48 V–800 V traction and charger systems.
Supply Voltage	4.5–5.5 V - compatible with standard automotive 5 V domains; ensures stable operation under battery voltage transients.
Current Rail Resistance	220 µΩ typical - minimizes power loss (e.g., <1.5 W at 82 A), critical for thermal management in compact OBC modules.
OCD Response Time	<1.0 µs - enables cycle-by-cycle overcurrent protection in SiC/GaN-based inverters and fast-switching converters.
Isolation Rating	1150 V_VIORM - meets reinforced insulation requirements for functional isolation between primary current path and secondary analog/digital interfaces.
Temperature Range	-40°C to +125°C (solder point) - qualified per AEC-Q100 Grade 1, supporting under-hood and powertrain applications.
Output Configuration	Semi-differential analog (AOUT/VREF) - reduces common-mode noise in noisy power stages while maintaining ADC compatibility.

Pinout & Package

Package: PG-TISON-8-6, surface-mount, 8 mm × 8 mm × 1.8 mm body with exposed thermal pad - optimized for high-current PCB routing and thermal dissipation in space-constrained power modules.

Pin/Terminal	Circuit Role	Design Meaning
1 VDD	Power supply input	5 V nominal supply; requires local 100 nF ceramic decoupling near pin for noise immunity during fast load transients.
2 GND	Ground reference	Common return for supply, analog output, and DCDI; must be connected to low-impedance ground plane beneath thermal pad.
3 VREF	Reference voltage terminal	Configurable 1.25 V or 2.5 V reference input/output; sets quiescent output level (VOQ = VDD/2) and enables ratiometric calibration.
4 AOUT	Analog output signal	Differential output pair with VREF; delivers 0–5 V swing proportional to sensed current; bandwidth >250 kHz.
5 OCD	Over-current detection output	Open-drain active-low flag; asserts within 1 µs when current exceeds programmable threshold; requires external pull-up.
6 DCDI	Digital control/diagnostic interface	One-wire UART interface; supports EEPROM read/write, temperature readout, and safety status polling; open-drain I/O.
7 IP−	Negative current terminal	Low-side connection point for integrated current rail; carries return current; must be routed with symmetric copper geometry.
8 IP+	Positive current terminal	High-side connection point for integrated current rail; carries main current path; defines directionality for polarity-sensitive outputs.

Key Features

Feature	Design Value
Coreless differential sensing	Eliminates magnetic saturation and hysteresis errors; enables accurate measurement of fast transient currents up to 250 A peak.
In-system EEPROM programming	Allows field calibration of OCD thresholds and sensitivity via DCDI-no rework or component replacement needed post-assembly.
Stray field suppression	≥40 dB rejection of external magnetic interference (e.g., adjacent inductors or busbars), verified per IEC 61000-4-8.
ASIL B Safety Element out of Context	Provides documented failure modes, FIT rate, and diagnostic coverage metrics-enables integration into ISO 26262-compliant systems without additional hardware redundancy.
Ultra-low insertion loss	220 µΩ resistance minimizes self-heating (<1.5 W at 82 A), reducing thermal derating needs and enabling smaller heatsinks in OBC designs.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-accuracy coreless current sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ACS724LLCTR-80AU-T	80 A range, 5 V supply, but uses open-loop Hall with flux concentrator; higher hysteresis (±0.2%) and lower bandwidth (80 kHz).	Lacks ASIL B certification and EEPROM programmability; not suitable for functional safety architectures requiring diagnostic coverage.	Select only for cost-sensitive non-automotive applications where fast transient fidelity and safety compliance are not required.
TMCS1108A4U	80 A range, 5 V supply, galvanically isolated amplifier architecture; fixed gain, no OCD output or DCDI interface.	No over-current detection flag or in-system calibration; requires external comparator and microcontroller for diagnostics.	Choose when analog output simplicity is prioritized over integrated safety features and field-programmable thresholds.

Compared with ACS724LLCTR-80AU-T and TMCS1108A4U, the TLE4973R075T5S0001XUMA1 uniquely combines ASIL B readiness, sub-µs OCD, and in-system EEPROM configuration-making it the only option that satisfies both high-fidelity current measurement and functional safety requirements in automotive-grade OBCs and inverters.

FAQ

What is the default output mode and how is it configured?

The TLE4973R075T5S0001XUMA1 ships pre-configured for semi-differential output mode (AOUT relative to VREF), with quiescent output at VDD/2. This mode is set via factory-programmed EEPROM and can be changed using the DCDI interface to fully-differential or single-ended (AOUT-only) - though single-ended is disabled by default per design constraints in Table 1.

Does the device require external calibration after soldering?

No external calibration is required: the TLE4973R075T5S0001XUMA1 is pre-calibrated over temperature at Infineon's production test floor. End-of-line calibration is optional and supported via DCDI for applications needing tighter tolerance; it adjusts sensitivity and offset using on-chip EEPROM storage without hardware modification.

How is galvanic isolation achieved and what standards does it meet?

Isolation is implemented via molded-package dielectric barrier between the integrated current rail (IP+/IP−) and signal pins (VDD, AOUT, DCDI), rated at 1150 V_VIORM per IEC 60747-17. Partial discharge withstand is ≥1200 V, satisfying reinforced insulation requirements for functional isolation in automotive and industrial equipment per IEC 61800-5-1 and UL 62368-1.

Can multiple TLE4973 sensors share a single DCDI bus?

Yes - the DCDI interface supports multi-drop configuration with auto-addressing, allowing up to eight TLE4973 devices on one bus. Each unit acquires a unique address during power-up based on internal trimming, eliminating manual dip-switch or resistor-based addressing and simplifying system-level diagnostics in multi-phase inverters or modular UPS units.
