Infineon Technologies TLE5009E1010FUMA1

Overview

TLE5009E1010FUMA1 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 3.3 V supply, achieves ±0.5° total angle error (typ.) over -40°C to 150°C, features integrated overvoltage detection and differential vector-length safety check, and targets automotive steering angle and EPS applications.

For engineers reviewing the TLE5009E1010FUMA1 datasheet, TLE5009E1010FUMA1 pinout, TLE5009E1010FUMA1 application, or TLE5009E1010FUMA1 equivalent, key selection criteria include its 3.3 V supply compatibility, differential output architecture, built-in safety diagnostics, temperature-compensated GMR sensing, and AEC-Q100 qualification for automotive use.

Technical Context

The TLE5009E1010FUMA1 implements two orthogonal GMR Wheatstone bridges to sense magnetic field orientation, generating raw differential sine and cosine signals. These are amplified, temperature-compensated, and offset-adjusted in analog domain before output - eliminating dependence on external ADC reference stability.

Its safety architecture includes internal diagnosis of supply overvoltage and external differential vector-length validation (±10% valid range), enabling ASIL-B compliance in system-level designs. Calibration at two temperatures (−40°C and 150°C) reduces orthogonality and gain mismatch errors, achieving <0.5° total angle error in differential mode.

FAQ

What is the recommended PCB layout practice for TLE5009E1010FUMA1 to ensure optimal thermal and EMC performance?

Mount the device with its exposed thermal pad fully soldered to a dedicated copper pour connected to GND via ≥4 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). Route differential SIN/COS traces as matched-length, tightly coupled pairs (≤50 Ω characteristic impedance), avoid crossing split planes, and place 100 nF ceramic decoupling capacitor between VDD and GND within 3 mm of the pins.

Does TLE5009E1010FUMA1 require external calibration in end-system applications?

No - the device undergoes factory calibration at two temperatures (−40°C and +150°C) to correct gain, offset, and orthogonality errors. End-system calibration is optional and only needed if higher than ±0.5° accuracy is required or if mechanical tolerances introduce additional misalignment beyond the sensor's specified air gap limits (0.5–3.0 mm).

How does the differential vector-length check function, and what circuitry is needed externally?

The vector-length check requires measuring the differential outputs SINP−SINN and COSP−COSN, squaring and summing them externally (e.g., using analog multipliers/comparators), then verifying the result falls within 0.81–1.21 × (VDD/2)². Infineon recommends using an external comparator (e.g., TLV3701) with hysteresis to detect out-of-range conditions.

Can TLE5009E1010FUMA1 operate with a 5 V supply?

No - TLE5009E1010FUMA1 is specified exclusively for 3.3 V supply (3.0–3.6 V). Using 5 V exceeds absolute maximum ratings and will damage the device. For 5 V systems, select the TLE5009-E2010 variant, which shares identical functionality but is trimmed and rated for 4.5–5.5 V operation.
