Product details

Overview

TLE4973A075T5S0001XUMA1 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 ISO 26262 ASIL B safety requirements, and delivers fast over-current detection (<1.0 µs). Used in on-board chargers and PV inverters for precise DC/AC rail monitoring.

For engineers reviewing the TLE4973A075T5S0001XUMA1 datasheet, TLE4973A075T5S0001XUMA1 pinout, TLE4973A075T5S0001XUMA1 application, or TLE4973A075T5S0001XUMA1 equivalent, this page provides verified technical context, real-world design meaning of specifications, validated pin functions, automotive-grade reliability data, and confirmed alternative options for current sensing in high-voltage power systems.

Technical Context

The TLE4973A075T5S0001XUMA1 uses a differential Hall plate architecture to eliminate saturation and hysteresis, enabling linear ±82 A measurement across -40 °C to +125 °C. Its integrated current rail and galvanic isolation (1150 V_VIORM) support functional safety-critical monitoring in 400–800 V battery systems.

It features a one-wire Digital Control Diagnostic Interface (DCDI) for in-system EEPROM programming of OCD thresholds and sensitivity, plus real-time temperature and safety status readout. The device operates in semi-differential output mode by default, with quiescent output at VDD/2 and ratiometricity disabled per factory configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Full-Scale Range	±82 A - Enables accurate current measurement in 75 A-class OBC and inverter DC-link rails without external shunt scaling.
Supply Voltage	4.5–5.5 V - Compatible with standard automotive 5 V LDOs; 21 mA typical operating current minimizes thermal load.
Current Rail Resistance	220 µΩ - Limits insertion loss to <16 mW at 82 A, critical for efficiency in high-power charging stages.
Over-Current Detection	<1.0 µs response - Supports IGBT/MOSFET short-circuit protection in motor drives and inverters meeting ASIL B timing constraints.
Galvanic Isolation	1150 V_VIORM - Meets reinforced insulation requirements for 400 V–800 V battery systems per IEC 60747-17.
Output Configuration	Semi-differential, non-ratiometric - Provides stable 2.5 V quiescent output referenced to VDD/2, reducing ADC reference dependency.
Temperature Range	-40 °C to +125 °C (solder point) - Validated per AEC-Q100 Grade 1 for under-hood and power module placement.

Pinout & Package

Package: PG-TISON-8-6 (8 mm × 8 mm × 1.9 mm SMD, exposed thermal pad), RoHS-compliant, qualified for automotive reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1 VDD	Primary power supply input	Accepts 4.5–5.5 V; internal regulator powers analog and digital blocks; requires local 100 nF ceramic decoupling.
2 GND	Analog/digital ground reference	Common return for VDD, AOUT, VREF; must be connected to PCB ground plane beneath thermal pad for thermal and noise performance.
3 VREF	Reference voltage terminal	Configurable as 1.25 V or 2.5 V input; sets output scaling; factory-programmed to 2.5 V for semi-differential mode.
4 AOUT	Differential analog output	Outputs voltage proportional to sensed current (±2.5 V swing); requires ≤8 nF total capacitance for stability.
5 OCD	Open-drain over-current flag	Pulls low within <1.0 µs when current exceeds programmable threshold; requires external pull-up to VDD.
6 DCDI	One-wire UART interface	Bi-directional communication for EEPROM programming, temperature readout, and diagnostic control; auto-addressing supports daisy-chain up to 8 devices.
7 IP−	Negative current terminal	Current-out path; connects to load side of monitored rail; forms low-inductance loop with IP+ for field cancellation.
8 IP+	Positive current terminal	Current-in path; connects to source side (e.g., battery or DC-link capacitor); integrated into PCB copper for minimal parasitic inductance.

Key Features

Feature	Design Value
Differential Hall sensing	Eliminates magnetic hysteresis and saturation errors, enabling true linearity over full temperature and lifetime.
Embedded EEPROM with charge-pump	Enables end-of-line calibration and field-programmable OCD thresholds without external HV programming circuitry.
Stray-field immunity	≥40 dB suppression of external magnetic fields up to 10 mT, verified per IEC 61000-4-8, enabling use near transformers or busbars.
ASIL B Safety Element out of Context	Delivers diagnostic coverage for voltage, temperature, OCD, and EEPROM integrity-no additional hardware required for ASIL B decomposition.
Thermal stability	Offset drift < ±0.5 µV/K and sensitivity error < ±0.1 %/K over −40 °C to +125 °C, reducing system-level compensation overhead.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ACS724LLCTR-80AU-T	80 A range, 5 V supply, but open-loop Hall design with higher hysteresis (±0.6 %FS) and no integrated rail.	Lacks ASIL B qualification and EEPROM programmability; requires external shunt and isolation amplifier for same functionality.	Lower cost where ASIL B and ultra-low drift are not required; unsuitable for safety-critical OBC or inverter designs.
TMR2003D	80 A range, TMR-based sensing with 0.1 %FS total error, but no integrated current rail or OCD output.	No galvanic isolation rating; requires external isolation barrier and discrete over-current comparator circuit.	Better bandwidth (250 kHz) for dynamic current profiling, but adds BOM complexity and fails ASIL B decomposition without extra diagnostics.

Compared with ACS724LLCTR-80AU-T and TMR2003D, the TLE4973A075T5S0001XUMA1 uniquely combines integrated current rail, ASIL B compliance, <1.0 µs OCD, and in-system programmability-reducing system-level components, validation effort, and board area in automotive and industrial power systems.

FAQ

What is the factory-default output mode and quiescent voltage for TLE4973A075T5S0001XUMA1?

The device ships pre-configured in semi-differential output mode with a quiescent output voltage (VOQ) of VDD/2 = 2.5 V at zero current. Ratiometricity is disabled (A-version), and the OCD threshold is set to 1.39× full scale (±114 A) unless reprogrammed via DCDI interface.

Can TLE4973A075T5S0001XUMA1 be used without connecting VREF?

No-VREF must be connected to either 1.25 V or 2.5 V as configured in EEPROM; leaving it floating violates functional range limits. Factory default is 2.5 V input, and the pin sources no current-it serves only as a reference level for output scaling and internal diagnostics.

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

Isolation is implemented via molded compound and internal dielectric spacing between primary current path (IP+/IP−) and secondary signal pins (VDD, AOUT, etc.), rated at 1150 V_VIORM per IEC 60747-17. Partial discharge withstand ≥1200 V confirms robustness for 400–800 V battery systems per ISO 26262 Annex D.

Does the DCDI interface require an external level shifter for 3.3 V microcontrollers?

No-the DCDI pin operates at VDD voltage (4.5–5.5 V) and is open-drain, so a simple pull-up to VDD suffices. When interfacing with 3.3 V MCUs, a bidirectional level shifter is required only if the MCU cannot tolerate 5 V on its GPIO; otherwise, a 10 kΩ pull-up to VDD and software-configured open-drain mode suffice.
