Product details

Overview

TLE4971A075T5E0001XUMA1 from Infineon is a high-precision, coreless magnetic current sensor in PG-TISON-8-6 package, designed for automotive-grade DC/AC current sensing up to ±75A full scale. It delivers 120–210 kHz bandwidth, <±1.5% sensitivity error at 25°C, 220 µΩ insertion resistance, and galvanic isolation up to 1150 V_peak VIORM. Used in onboard chargers and motor inverters where stray-field immunity and fast over-current detection are critical.

For engineers reviewing the TLE4971A075T5E0001XUMA1 datasheet, TLE4971A075T5E0001XUMA1 pinout, TLE4971A075T5E0001XUMA1 application, or TLE4971A075T5E0001XUMA1 equivalent, key selection criteria include ±75A full-scale range, semi-differential analog output with 1.65 V quiescent voltage, dual open-drain OCD outputs with programmable thresholds, and EEPROM-configurable blanking/filter timing.

Technical Context

The TLE4971A075T5E0001XUMA1 implements a differential Hall plate architecture with integrated current rail, enabling coreless operation and <1 nH parasitic inductance. Its on-chip EEPROM stores user-programmable parameters including OCD1/OCD2 thresholds (e.g., 1.25× and 0.82× full scale), deglitch filter time (configurable down to 0 µs), and output mode (semi-differential default).

It uses monolithic Hall technology with self-diagnostic capability and operates across –40°C to +125°C ambient, maintaining ±2.0% sensitivity error over temperature and ±230 mA offset drift. The device ships fully calibrated and supports Lead Tip Inspection (LTI) for automated solder-joint quality verification.

Key Specifications

4 AOUT	Analog signal output	Semi-differential output: 1.65 V ± (16 mV/A × IPN); drives up to ±2 mA into 6.8 nF load.
5 OCD1	Over-current detection 1	Open-drain, active-low; threshold = 1.25 × ±75 A = ±93.75 A; no external pull-up required for wired-AND.
6 OCD2	Over-current detection 2	Open-drain, active-low; threshold = 0.82 × ±75 A = ±61.5 A; independent deglitch filtering.
7 IP–	Negative current terminal	Current-out pin of integrated 220 µΩ rail; connects to load side of monitored conductor.
8 IP+	Positive current terminal	Current-in pin of integrated rail; connects to source side (e.g., battery/inverter output).

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 (120 kHz), higher offset drift (±1.5% FS), no EEPROM programming, 2.5 kVRMS isolation.	Targeted at cost-sensitive industrial drives; lacks LTI and ISO 26262 documentation.	Select when functional safety certification is not required and OCD configurability is unnecessary.
TMCS1108A4U	Wider supply range (3–5.5 V), ratiometric output, lower sensitivity error (±0.8%), but only 100 kHz bandwidth and no dual OCD outputs.	Preferred for general-purpose industrial monitoring; lacks automotive qualification and VIORM rating.	Select for non-automotive applications needing wide-VDD flexibility and minimal offset, but not ultra-fast fault response.

Compared with ACS724LLCTR-75AB-T and TMCS1108A4U, the TLE4971A075T5E0001XUMA1 uniquely combines automotive ASIL-ready diagnostics, dual independently configurable OCD outputs, LTI-enabled manufacturability, and 210 kHz bandwidth - making it optimal for safety-critical, high-switching-frequency traction and charging systems.

FAQ

What output modes does the TLE4971A075T5E0001XUMA1 support, and which is factory-default?

The device supports single-ended, fully-differential, and semi-differential analog output modes, all configurable via EEPROM. Semi-differential is the factory-default mode, delivering a 1.65 V quiescent voltage on VREF and a proportional signal on AOUT. This mode eliminates external reference components and simplifies PCB layout while maintaining high noise immunity.

How is over-current detection configured, and what are the default thresholds for this part number?

Two independent open-drain OCD outputs (OCD1 and OCD2) are provided, each with user-programmable thresholds and deglitch filters. For TLE4971A075T5E0001XUMA1, default OCD1 threshold is 1.25 × ±75 A = ±93.75 A, and OCD2 is 0.82 × ±75 A = ±61.5 A. Both thresholds are stored in EEPROM and can be updated in-system using the Serial Inspection and Configuration Interface (SICI).

Does the TLE4971A075T5E0001XUMA1 require external calibration after soldering?

No. The device ships fully calibrated from Infineon, with all sensitivity, offset, and linearity corrections pre-programmed into on-chip memory. No end-of-line calibration is needed - the ±1.5% total error specification at 25°C is guaranteed out-of-box, reducing test time and manufacturing complexity.

What is the thermal performance of the PG-TISON-8-6 package under continuous 75 A RMS operation?

On Infineon's reference PCB (140 µm copper), the thermal resistance from current rail to soldering point is 0.25 K/W. At 75 A RMS, power dissipation is ~1.24 W (I²R = 5625 × 220 µΩ), resulting in ~0.31 K temperature rise above board temperature - well within the –40°C to +125°C ambient operating range and supporting 8-year lifetime at 32 A RMS per reliability data.
