Product details
Overview
TLE5012BE5000XUMA1 from Infineon Technologies is a GMR-based 360° absolute angle sensor with integrated sine/cosine signal processing, 15-bit angle resolution (0.01°), bi-directional SSC interface up to 8 Mbit/s, and automotive-grade operation from −40°C to +150°C junction temperature. It delivers calibrated angle output with ≤1.0° total error over lifetime and temperature when auto-calibration is enabled, and supports PWM, SPC, HSM, and IIF interfaces for motor commutation in electric power steering (EPS) systems.
For engineers reviewing the TLE5012BE5000XUMA1 datasheet, TLE5012BE5000XUMA1 pinout, TLE5012BE5000XUMA1 application in EPS or rotary position sensing, or TLE5012BE5000XUMA1 equivalent for SIL-compliant angular measurement, this page provides verified functional context, interface configuration details, diagnostic capabilities, and validated alternative options aligned with AEC-Q100 qualification.
Technical Context
The TLE5012BE5000XUMA1 implements dual sigma-delta ADCs for simultaneous high-precision digitization of X/Y GMR bridge outputs and on-chip temperature sensing. Its digital signal processing unit performs CORDIC-based arctangent computation and revolution counting using raw sine/cosine data, delivering 16-bit sine/cosine and 15-bit absolute angle values.
It integrates a PLL clock system configurable for internal oscillator or external clock input via IFC pin (in PWM/SPC mode), supports concurrent active interfaces (e.g., SSC + PWM), and embeds PRO-SIL™ safety mechanisms including 8-bit CRC for SSC, 4-bit CRC nibble for SPC, BIST routines for ISM/ADC/CORDIC/CCU, and supply monitoring with overvoltage/undervoltage detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMR-based angular position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5055A-DSOT | 14-bit resolution (0.022°), SPI-only interface, no integrated auto-calibration, operates to +125°C only. | Lacks AEC-Q100 qualification and SIL-supporting diagnostics; suitable for non-safety-critical industrial encoders. | Select when cost sensitivity outweighs automotive qualification and functional safety requirements. |
| TLE5012B E1000XUMA1 | Same die, pre-configured for Incremental Interface (IIF) with quadrature A/B/Z outputs; identical GMR core and calibration. | Used where legacy microcontrollers require ABZ encoder signals instead of digital angle values or PWM. | Choose for drop-in replacement in existing IIF-based EPS ECUs without firmware changes to angle interpretation logic. |
Compared with AS5055A-DSOT, TLE5012BE5000XUMA1 delivers higher resolution, extended temperature range, and integrated safety features essential for ASIL-B systems; versus E1000XUMA1, it trades quadrature outputs for deterministic PWM encoding - optimizing for MCU resource-constrained designs requiring single-wire angle transmission.

FAQ
What interface modes are pre-configured in the TLE5012BE5000XUMA1 variant?
The E5000 suffix denotes factory-programmed configuration for Pulse Width Modulation (PWM) interface operation. It outputs absolute angle as a duty-cycle-modulated signal on the dedicated PWM pin, with optional SSC co-use for configuration or diagnostics. No firmware or register writes are needed to activate PWM mode - it is operational immediately after power-up with VDD within 4.5–5.5 V.
Does the TLE5012BE5000XUMA1 require an external magnet, and what is the recommended placement?
Yes, it requires an external diametrically magnetized 2-pole magnet positioned above the package top surface, centered over the die. The magnet's rotational axis must align with the sensor's Z-axis (perpendicular to package surface), and air gap should be 0.5–2.0 mm. No back-biasing or flux concentration is needed - the integrated iGMR bridges directly sense field orientation in-plane.
How does the auto-calibration function improve long-term accuracy, and is host intervention required?
Auto-calibration continuously corrects for thermal drift and magnetic hysteresis by updating internal offset/gain coefficients stored in flip-flops. It runs automatically during normal operation when enabled via SSC register write (default off). No host MCU action is needed once activated - the algorithm executes in background using idle cycles and requires no additional pins or timing resources.
Can multiple TLE5012BE5000XUMA1 sensors share the same PWM output line?
No - PWM is a unidirectional, single-sensor output protocol. However, multiple TLE5012B devices (including E5000 variants) can share a single SSC bus using individual CSQ lines, enabling daisy-chained or star-topology configurations. For multi-sensor PWM systems, each device requires its own dedicated PWM trace to avoid signal contention.
