Infineon Technologies TLE5009E2010FUMA1

Overview

TLE5009E2010FUMA1 from Infineon Technologies is a GMR-based contactless angular position sensor delivering differential analog sine/cosine outputs for 0–360° absolute angle measurement. It operates from 4.5–5.5 V supply, achieves ±0.5° total angle error (max) over –40°C to +150°C, and features integrated overvoltage detection and differential vector-length safety check. Used in automotive EPS motor commutation and throttle valve position sensing.

For engineers reviewing the TLE5009E2010FUMA1 datasheet, TLE5009E2010FUMA1 pinout, TLE5009E2010FUMA1 application, or TLE5009E2010FUMA1 equivalent, key selection criteria include differential output amplitude (0.8 × V_DD), temperature-compensated GMR bridge stability, built-in safety diagnostics, and AEC-Q100 Grade 0 qualification for under-hood deployment.

Technical Context

The TLE5009E2010FUMA1 implements two orthogonal GMR Wheatstone bridges biased by on-chip current sources, generating analog sine and cosine signals proportional to magnetic field orientation. Signal conditioning includes chopper-stabilized amplification and temperature compensation via on-die reference elements.

Its safety architecture integrates dual-path diagnosis: internal monitoring of supply voltage, bandgap reference, and oscillator frequency, plus external differential vector-length validation (V_sin² + V_cos² within 0.55–0.95 × V_DD²). Calibration at two temperatures (–40°C and +150°C) enables <±0.5° total angle error across full operating range.

FAQ

What is the purpose of the ERR pin on the TLE5009E2010FUMA1?

The ERR pin is an open-drain, active-low fault indicator that asserts when internal diagnostics detect overvoltage, oscillator failure, or external differential vector-length violation (V_sin² + V_cos² outside 0.55–0.95 × V_DD²). It requires an external pull-up resistor and interfaces directly with MCU GPIO or safety monitor ICs for real-time fault response without software polling.

Can the TLE5009E2010FUMA1 operate with a 3.3 V supply?

No. The TLE5009E2010FUMA1 is specifically designed for 5 V systems (4.5–5.5 V range); its output amplitude is trimmed to 0.8 × V_DD, and internal regulators require minimum 4.5 V to function correctly. For 3.3 V applications, use the pin-compatible TLE5009E1010FUMA1 variant instead.

How does the differential vector-length check improve functional safety?

This hardware-level diagnostic continuously verifies that the sum of squared sine and cosine outputs remains within 0.55–0.95 × V_DD², detecting open-circuit, short-to-rail, magnet detachment, or severe misalignment. It satisfies ASIL-B fault coverage requirements per ISO 26262 without relying on MCU firmware, enabling fail-safe shutdown or fallback mode activation within microseconds.

Is PCB layout guidance available for minimizing EMI on the analog outputs?

Yes. Infineon recommends symmetric 50 Ω differential routing for VOUT_SIN± and VOUT_COS± pairs, ground plane beneath all signal layers, separation from switching power traces (>3 mm), and direct connection of the exposed thermal pad to a solid GND plane. These practices reduce common-mode noise and maintain <0.1° angle error contribution from layout-induced imbalance.
