Product details

Overview

TLE5012BE5020XUMA1 from Infineon Technologies is a GMR-based 360° absolute angle sensor with integrated sine/cosine signal processing, 15-bit angle resolution (0.01°), ±1.0° total angle error over temperature and lifetime with auto-calibration enabled, and dual SD-ADCs for high-precision magnetic field measurement - deployed in electric power steering (EPS) motor commutation and steering angle sensing.

For engineers reviewing the TLE5012BE5020XUMA1 datasheet, TLE5012BE5020XUMA1 pinout, TLE5012BE5020XUMA1 application, or TLE5012BE5020XUMA1 equivalent, this part supports SSC, PWM, SPC, HSM, and IIF interfaces; delivers SIL-compliant diagnostics; operates from −40°C to +150°C junction; and features configurable push-pull/open-drain outputs for automotive angular position feedback systems.

Technical Context

The TLE5012BE5020XUMA1 implements a dual-channel sigma-delta ADC architecture to digitize analog sine and cosine signals from monolithic iGMR elements, followed by CORDIC-based angle computation and revolution counting. Its digital signal processing unit includes a dedicated CCU for incremental output generation and ISM for interface state management.

It integrates a PLL that accepts either internal oscillator or external clock via IFC pin (in PWM/SPC mode), enabling synchronization with host controllers. Safety mechanisms include BIST for ADC, CORDIC, CCU, and ISM; 8-bit CRC on SSC; 4-bit CRC nibble on SPC; and overvoltage/undervoltage detection on VDD.

Applications

Electric Power Steering (EPS)

Steering Column Angle Sensing

Use Scenario: Real-time rotor position feedback for field-oriented control (FOC) of 3-phase BLDC motors in column-assist EPS systems.

IC Role / Device Role / Timing Role: Primary absolute angle sensor providing 15-bit position and speed data via SSC or PWM to MCU for torque vectoring and assist mapping.

Use Value: Enables <1.0° angle error across full temperature range, directly improving steering responsiveness and reducing mechanical backlash compensation.

Use Scenario: Measuring absolute steering wheel rotation angle for vehicle stability control (VSC) and lane-keeping assist (LKA) functions.

IC Role / Device Role / Timing Role: High-reliability angle transducer delivering synchronized SPC or PWM output to ADAS domain controller with CRC-verified data integrity.

Use Value: Supports ASIL-B compliance through built-in diagnostics and 150°C operation, eliminating need for external safety monitors.

Rotary Position Switches

Throttle/Valve Actuator Feedback

Use Scenario: Contactless angular encoding in gear-shift selectors and mode-dial interfaces requiring >10M cycle lifetime and no wear-out.

IC Role / Device Role / Timing Role: Non-contact rotary encoder replacing potentiometers; outputs incremental (IIF) or Hall-switch (HSM) signals compatible with legacy MCU inputs.

Use Value: Delivers consistent 0.01° resolution and immunity to dust/moisture - critical for infotainment and HVAC control panels.

Use Scenario: Closed-loop position feedback for electronic throttle bodies and variable valve timing actuators in ICE powertrains.

IC Role / Device Role / Timing Role: Redundant-capable angle sensor supplying dual independent outputs (e.g., SSC + PWM) to engine control unit for fault-tolerant actuation.

Use Value: Dual SD-ADC channels and auto-calibration ensure <±1.0° accuracy over 15-year service life, meeting OEM durability targets.

Equivalent & Alternatives

The following parts are listed as comparable options for similar GMR-based absolute angle sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AS5055A-DSOT	14-bit resolution (0.022°), single SD-ADC, no built-in auto-calibration, SPI-only interface, max 125°C junction.	Limited to cabin/non-under-hood applications; lacks SIL diagnostics and dual-interface flexibility.	Select when cost-sensitive non-safety-critical rotary encoders are needed and thermal range ≤125°C.
TLE5012B E5000 XUMA1	Same die, pre-configured for PWM-only output (no SSC/SPI capability), identical accuracy and temperature rating.	Used where only PWM feedback is required (e.g., legacy ECUs without SPI), simplifying firmware integration.	Choose for PWM-only systems to avoid unused interface overhead and reduce configuration complexity.

Compared with AS5055A-DSOT, TLE5012BE5020XUMA1 offers higher resolution, extended temperature range, and functional safety features; versus E5000, it adds SSC for configuration and diagnostics - making it optimal for next-gen EPS and ADAS platforms requiring flexibility and traceability.

FAQ

What interface modes does TLE5012BE5020XUMA1 support out-of-the-box?

This variant is pre-configured for PWM and SPC interfaces, with SSC enabled for configuration and diagnostics. It supports simultaneous operation of PWM and SSC, or SPC and SSC, but not PWM+SPC together. All five interfaces (SSC, PWM, SPC, HSM, IIF) are physically implemented and can be activated via register writes over SSC - no hardware change required.

How does the auto-calibration function improve long-term accuracy?

The auto-calibration algorithm runs continuously during operation, correcting for temperature-induced gain/offset drift and long-term magnetic hysteresis using internal reference paths and stored laser-fuse parameters. When enabled, it reduces total angle error to ≤±1.0° across −40°C to +150°C and 15+ years, eliminating periodic recalibration in fielded systems.

Can TLE5012BE5020XUMA1 operate in multi-sensor bus configurations?

Yes - both SSC and SPC interfaces support multi-drop bus operation. With SSC, up to 4 sensors share one bus using individual CSQ lines or daisy-chained DATA lines. With SPC, multiple sensors time-multiplex onto a single line using master-trigger synchronization via the IFC pin, enabling compact multi-axis designs in tight EPS packaging.

Is external magnetic calibration required before deployment?

No - the device ships pre-calibrated with parameters stored in laser fuses. During power-up, these values initialize internal registers, enabling immediate high-accuracy operation. Optional runtime auto-calibration further refines accuracy without user intervention or external equipment, making it ideal for automated manufacturing and field deployment.
