Infineon Technologies TLE5501E0002XUMA1

Overview

TLE5501E0002XUMA1 from Infineon is a TMR-based 360° automotive angle sensor with dual independent Wheatstone bridges, ISO26262 ASIL-D compliance (with external safety mechanisms), differential sine/cosine outputs up to 0.37 V/V, and operation from −40°C to +150°C ambient. It enables redundant external angle calculation for high-diagnostic-coverage steering angle sensing and BLDC motor commutation.

For engineers reviewing the TLE5501E0002XUMA1 datasheet, TLE5501E0002XUMA1 pinout, TLE5501E0002XUMA1 application, or TLE5501E0002XUMA1 equivalent, key selection criteria include de-coupled bridge architecture, dual VDD/GND supply isolation, ratiometric output behavior, and functional safety integration requirements per ISO26262 Part 10.

Technical Context

The device integrates eight TMR resistors arranged as two physically and electrically isolated Wheatstone bridges - P-bridge (pins 1,3,4,5,6) and N-bridge (pins 1,5,6,7,8) - each generating independent differential sine and cosine signals. Bridge decoupling enables cross-checking of angle results for fault detection.

It operates ratiometrically with supply-dependent output scaling, requires no external amplification due to large signal amplitude (0.37 V/V), and supports both single-ended and differential ADC interfacing. Safety functions include diagnostic coverage via signal redundancy, but full ASIL-D compliance depends on external safety mechanisms per Infineon's Safety Manual.

FAQ

What distinguishes TLE5501E0002XUMA1 from the E0001 variant?

The E0002 variant features fully decoupled P- and N-bridges with independent VDD and GND pins for each, enabling hardware-level signal redundancy and cross-checking required for ISO26262 ASIL-D compliance. In contrast, E0001 shares a single supply and ground, offering only QM-level safety and pin compatibility with TLE5009.

Does TLE5501E0002XUMA1 require external signal conditioning?

No. Its differential sine/cosine outputs deliver up to 0.37 V/V ratiometric amplitude, sufficient to drive standard 12-bit differential-input ADCs directly without amplification or level-shifting. A low-pass buffer capacitor (e.g., 100 nF) may be added for noise filtering based on magnetic field slew rate.

How is ASIL-D compliance achieved with this sensor?

ASIL-D compliance is system-level and requires external safety mechanisms - such as dual-core lockstep MCUs, hardware watchdogs, or dedicated safety monitors - to validate cross-bridge consistency and manage failure reactions. Infineon provides a Safety Manual and Safety Analysis Summary Report to support integration into ASIL-D architectures.

What is the maximum allowable magnetic field exposure?

The absolute maximum magnetic field is 150 mT for up to 5 hours at 25°C ambient. Exposure beyond this limit risks irreversible TMR element degradation. For continuous operation, magnetic fields should remain below 100 mT to ensure long-term stability and angle accuracy within specification.
