Infineon Technologies TLE5501E0001XUMA1

Overview

TLE5501E0001XUMA1 from Infineon Technologies is a 360° Tunneling Magneto Resistance (TMR)-based angle sensor with differential sine/cosine outputs, ratiometric operation, and AEC-Q100 Grade 0 qualification (−40°C to +150°C). It delivers up to 0.37 V/V output signal amplitude for direct microcontroller ADC interface without external amplification, and features pin compatibility with TLE5009 in PG-DSO-8 package for automotive steering angle sensing and BLDC motor commutation.

For engineers reviewing the TLE5501E0001XUMA1 datasheet, TLE5501E0001XUMA1 pinout, TLE5501E0001XUMA1 application, or TLE5501E0001XUMA1 equivalent, key selection criteria include its TMR-based angular resolution, differential bridge architecture, E0001 derivative's single-supply configuration, AEC-Q100 Grade 0 thermal rating, and functional safety classification as QM (Quality Management).

Technical Context

The TLE5501E0001XUMA1 implements two discrete Wheatstone bridges using eight TMR resistors to sense magnetic field orientation, generating analog differential outputs for sine (SIN_P/SIN_N) and cosine (COS_P/COS_N) components. Its ratiometric output ensures immunity to supply voltage variation, and the absence of internal signal conditioning preserves raw bridge fidelity for external angle calculation.

This derivative uses a single VDD and shared GND pins (GND1/GND2 internally connected), with pin 5 unconnected - differing from TLE5009 where pin 5 provides temperature/diagnostic functions. The architecture supports high-precision 360° absolute angle measurement without interpolation or digital processing on-die.

FAQ

What is the maximum allowable magnetic field strength for TLE5501E0001XUMA1?

The device tolerates up to 200 mT for 5 minutes at 25°C ambient, or 150 mT continuously for 5 hours at 25°C. Exceeding these limits risks permanent TMR element degradation. Magnetic field exposure must remain within these bounds during assembly, testing, and end-use - especially near high-current motor windings or solenoids.

Does TLE5501E0001XUMA1 require external signal conditioning before ADC input?

No external amplification or filtering is required. Its 0.37 V/V output amplitude drives 12-bit+ microcontroller ADCs directly. A 100 nF buffer capacitor (Cb) is recommended between each differential pair and ADC input to limit bandwidth and improve noise immunity, but operation without Cb is supported if ADC sample-and-hold timing is adjusted accordingly.

How does pin 5 differ between TLE5501E0001XUMA1 and TLE5009E0001XUMA1?

In TLE5501E0001XUMA1, pin 5 is unconnected (n.c.) and internally tied to GND2. In TLE5009E0001XUMA1, pin 5 provides an analog temperature output and diagnostic signal. This difference enables pin-compatible replacement while requiring firmware updates to ignore or repurpose pin 5 in existing TLE5009 designs.

Is TLE5501E0001XUMA1 qualified for ASIL-B or higher functional safety levels?

TLE5501E0001XUMA1 is classified as QM (Quality Management) per ISO 26262, meaning it has no integrated safety mechanisms but is suitable for ASIL-B systems when combined with external diagnostics, redundant sensing, or software-based fault detection. For ASIL-D, the E0002 derivative with de-coupled bridges must be used alongside certified safety mechanisms.
