Product details

Overview

TLE4971A075N5E0001XUMA1 from Infineon is a high-precision, coreless magnetic current sensor in PG-TISON-8-5 package, designed for ±75 A DC/AC automotive current sensing with 16 mV/A sensitivity, 210 kHz bandwidth, and integrated 220 µΩ current rail. It delivers galvanic functional isolation up to 1150 V_peak, operates from −40 °C to +125 °C, and is pre-calibrated for OBC and motor inverter applications.

For engineers reviewing the TLE4971A075N5E0001XUMA1 datasheet, TLE4971A075N5E0001XUMA1 pinout, TLE4971A075N5E0001XUMA1 application, or TLE4971A075N5E0001XUMA1 equivalent, key selection criteria include full-scale range (±75 A), semi-differential analog output mode, dual open-drain OCD outputs with 1.25×/0.82× threshold factors, and EEPROM-programmable configuration without external components.

Technical Context

The TLE4971A075N5E0001XUMA1 implements differential Hall sensing with on-chip signal conditioning and self-diagnostic capability, enabling stray field suppression >50 dB up to 150 kHz. Its integrated current rail eliminates magnetic core losses and enables <1 nH parasitic inductance.

Configuration is stored in embedded EEPROM via Serial Inspection and Configuration Interface (SICI), supporting user-defined OCD blanking times, threshold scaling, and output mode selection (semi-differential by default). The device operates at 3.3 V supply with 18 mA typical current draw and 1.0–1.5 ms power-on delay.

Key Specifications

Parameter	Value and Actual Design Meaning

Sensitivity	16 mV/A - fixed gain in semi-differential mode; enables 1.65 V quiescent output at zero current
Bandwidth	210 kHz (−3 dB) - captures fast transients in SiC/GaN-based motor drives and charger switching waveforms
Current Rail Resistance	220 µΩ - limits conduction loss to <0.83 W at 75 A RMS, reducing thermal stress on PCB

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), no EEPROM programmability, 100 µΩ rail resistance	Lacks dual OCD outputs and magnetic field suppression >40 dB; not AEC-Q100 qualified	Select when cost sensitivity outweighs automotive qualification and advanced diagnostics
TMR2505-75A	Tunnel magnetoresistance (TMR) sensing, 300 kHz bandwidth, 150 µΩ rail, no integrated EEPROM	Higher sensitivity drift over temperature; requires external configuration logic for OCD behavior	Select for ultra-high bandwidth needs where external control of OCD timing is acceptable

Compared with ACS724LLCTR-75AB-T and TMR2505-75A, the TLE4971A075N5E0001XUMA1 uniquely integrates EEPROM-based configuration, dual independently programmable OCD outputs, and AEC-Q100 Grade 0 qualification-enabling single-part deployment across OBC, inverter, and BMS without redesign.

FAQ

What output mode is factory-configured for TLE4971A075N5E0001XUMA1?

The device ships pre-programmed in semi-differential output mode with 1.65 V quiescent voltage on VREF and proportional analog output on AOUT. This mode provides inherent common-mode rejection and eliminates need for external reference buffers while supporting both bidirectional and unidirectional current sensing configurations.

Can OCD1 and OCD2 be configured with different blanking times?

Yes-both OCD outputs support independent deglitch filter programming via EEPROM. Blanking time can be set per channel to suppress switching transients unique to each fault condition, such as inverter shoot-through versus overload events, without affecting analog measurement accuracy or latency.

Does TLE4971A075N5E0001XUMA1 require external calibration after soldering?

No. The sensor is delivered fully calibrated at Infineon's production test floor using traceable current standards. No end-of-line calibration is needed-only system-level verification of OCD thresholds and analog output linearity under actual operating conditions is recommended.

How is galvanic isolation achieved without a transformer or optocoupler?

Isolation is implemented through monolithic integration of Hall sensor, signal conditioning, and output drivers within a single die, separated from the current rail by thick-field oxide and deep trench isolation. The 1150 V_peak VIORM rating is validated per DIN EN 60747-17 and applies across the entire PG-TISON-8-5 package creepage/clearance geometry.
