Product details

Overview

TLE4971A075T5UE0001XUMA1 from Infineon is a high-precision coreless magnetic current sensor in PG-TISON-8-6 package, designed for ±75A DC/AC automotive current sensing with semi-differential analog output, 210kHz bandwidth, and two open-drain over-current detection outputs. It features 220µΩ insertion resistance, <1nH parasitic inductance, and galvanic isolation up to 1150V_peak VIORM, deployed in on-board chargers and motor inverters.

For engineers reviewing the TLE4971A075T5UE0001XUMA1 datasheet, TLE4971A075T5UE0001XUMA1 pinout, TLE4971A075T5UE0001XUMA1 application, or TLE4971A075T5UE0001XUMA1 equivalent, key selection criteria include full-scale range (±75A), OCD threshold programmability, semi-differential output mode, thermal derating at 105°C for 8-year operation, and EEPROM-configurable blanking times without external components.

Technical Context

The TLE4971A075T5UE0001XUMA1 implements a differential Hall plate architecture with integrated current rail, enabling stray-field suppression >50dB up to 150kHz and functional isolation per IEC 60747-17. Its signal path includes on-chip offset and gain calibration, temperature-compensated sensitivity, and dual independent OCD comparators with user-programmable thresholds (1.25× and 0.82× FS) and zero-filter time.

Configuration is stored in embedded EEPROM and accessed via Serial Inspection and Configuration Interface (SICI); output modes (semi-differential, single-ended, fully-differential) are selected at programming time. The device ships pre-calibrated and requires no end-of-line calibration, with quiescent voltage fixed at 1.65V in semi-differential mode and sensitivity of 16mV/A for ±75A full scale.

Key Specifications

Parameter	Value and Actual Design Meaning
Full Scale Range	±75A - defines maximum measurable bidirectional current before analog saturation or OCD activation
Sensitivity	16 mV/A - delivers 1.2V full-scale swing (75A × 16mV/A) on AOUT in semi-differential mode with 1.65V quiescent point
Bandwidth	210 kHz - supports accurate current capture in fast-switching SiC/GaN inverter applications up to 100kHz fundamental
Insertion Resistance	220 µΩ - limits power loss to ≤1.24W at 75A RMS, enabling compact thermal design without external shunt cooling
Isolation Voltage	1150 V_peak VIORM - meets reinforced insulation requirements for 400–800V battery systems per IEC 60747-17
OCD Response Time	≤1.5 µs - enables sub-microsecond fault shutdown in motor drives, independent of main analog path latency
Total Error (25°C)	±1.5% - combines sensitivity error, offset drift, and linearity for closed-loop current control accuracy without software compensation

Pinout & Package

Package: PG-TISON-8-6, 8×8mm SMD, lead-tip inspection (LTI) enabled, thermally enhanced with exposed thermal pad.

Pin/Terminal	Circuit Role	Design Meaning
1 VDD	Supply input	3.3V nominal supply; powers internal regulators, Hall sensors, and EEPROM; decoupling capacitor required
2 GND	Ground reference	Common return for supply, analog output, and OCD logic; must be low-impedance connection to minimize noise coupling
3 VREF	Reference output	Provides stable 1.65V internal reference in semi-differential mode; used as bias point for AOUT quiescent level
4 AOUT	Analog signal output	Single-ended output proportional to IPN; drives ±2mA load; 120–210kHz bandwidth with 6.8nF capacitive load
5 OCD1	Over-current detection 1	Open-drain output active-low at 1.25× FS (93.75A); configurable blanking time; supports wired-AND fault bus
6 OCD2	Over-current detection 2	Open-drain output active-low at 0.82× FS (61.5A); independent deglitch filter; enables tiered protection strategy
7 IP−	Negative current terminal	Current-out pin of integrated 220µΩ rail; connects to load side of monitored branch; forms low-inductance current loop
8 IP+	Positive current terminal	Current-in pin of integrated rail; connects to source side (e.g., inverter phase leg); defines measurement direction (+IPN = 8→7)

Key Features

Feature	Design Value
Coreless magnetic sensing	Eliminates saturation, hysteresis, and temperature drift of ferrous cores-enables stable ±75A measurement across −40°C to +125°C
Embedded EEPROM configuration	Stores OCD thresholds, blanking times, and output mode; enables field reprogramming without hardware change or BOM update
Dual independent OCD outputs	Supports hierarchical protection: fast response at 0.82× FS for soft faults, hard cutoff at 1.25× FS for short-circuit events
Lead Tip Inspection (LTI)	Optical solder-joint verification capability built into package geometry-reduces post-reflow AOI false calls in automotive manufacturing
Self-diagnostic function	Monitors Hall plate health, EEPROM integrity, and supply voltage; reports failure via OCD pin behavior or analog output anomaly

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-75AB-T	Lower bandwidth (120kHz), higher sensitivity error (±2.5%), no EEPROM programmability, 5V supply only	Lacks dual OCD outputs and LTI; not qualified to AEC-Q100 Grade 0; limited to non-safety-critical industrial use	Select when cost sensitivity outweighs functional safety requirements and 210kHz bandwidth is unnecessary

FAQ

What output mode is factory-configured for TLE4971A075T5UE0001XUMA1?

The TLE4971A075T5UE0001XUMA1 ships pre-configured in semi-differential output mode with 1.65V quiescent voltage on VREF and 16mV/A sensitivity. This mode uses internal reference generation, eliminates need for external reference voltage source, and provides optimal noise immunity for automotive environments.

Does TLE4971A075T5UE0001XUMA1 require external calibration after PCB assembly?

No. The device is shipped fully calibrated and does not require end-of-line calibration. All sensitivity, offset, and temperature compensation parameters are factory-trimmed and stored in EEPROM. Only system-level validation per application-specific test plan is needed.

How is galvanic isolation achieved without a transformer or optocoupler?

Isolation is implemented via monolithic integration: the Hall sensor die and signal conditioning circuitry are fabricated on one silicon island, while the current-carrying rail is a separate metal structure embedded in the same package. The 1150V_peak VIORM rating is certified per IEC 60747-17 for reinforced insulation across the mold compound barrier.

Can OCD1 and OCD2 be used simultaneously for different fault thresholds?

Yes. OCD1 and OCD2 operate independently with separate programmable thresholds (1.25× and 0.82× FS), blanking times, and deglitch filters. They can drive separate protection circuits or be wire-OR'd to generate a unified fault signal, enabling multi-level overcurrent response in safety-critical systems.
