Product details
Overview
TLE5012BE9000XUMA1 from Infineon Technologies is a GMR-based 360° absolute angle sensor with integrated sine/cosine sensing, 15-bit angle resolution (0.01°), ±1.0° total angle error over temperature and lifetime (with auto-calibration enabled), and Short PWM Code (SPC) interface pre-configured for SENT-compliant output. It operates from -40°C to +150°C junction temperature and delivers real-time angle, speed, and revolution count for motor commutation in electric power steering systems.
For engineers reviewing the TLE5012BE9000XUMA1 datasheet, TLE5012BE9000XUMA1 pinout, TLE5012BE9000XUMA1 application, or TLE5012BE9000XUMA1 equivalent, this page provides verified functional context, interface-specific timing behavior, diagnostic coverage (CRC, BIST, supply monitoring), and automotive-grade reliability data per AEC-Q100.
Technical Context
The TLE5012BE9000XUMA1 implements dual sigma-delta ADCs to digitize analog GMR bridge outputs, followed by CORDIC-based arctangent computation to derive absolute angle. Its digital signal processing unit includes a revolution counter and angular speed estimator, all operating on a PLL-synchronized clock derived either from an internal oscillator or external source via IFC pin (in SPC/PWM modes).
It integrates safety mechanisms including 4-bit CRC checksum per SPC frame, built-in self-test (BIST) for ISM, CORDIC, CCU, and ADCs at startup, plus overvoltage/undervoltage detection on VDD and GND-off monitoring - enabling compliance with ASIL-B requirements under ISO 26262 when used with appropriate system-level diagnostics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Resolution | 15-bit absolute angle output = 0.01° quantization step; enables precise rotor position tracking in EPS motors. |
| Angle Accuracy | Max. ±1.0° total error over -40°C to +150°C and lifetime with auto-calibration active; supports high-reliability steering control. |
| Interface Type | Pre-configured Short PWM Code (SPC) compliant with SAE J2716; delivers angle, speed, status, and CRC in single SENT-like frame. |
| Operating Temp | -40°C to +150°C junction temperature range; qualified per AEC-Q100 Grade 0 for under-hood automotive use. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMR-based angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMS AS5055A | 14-bit resolution, SPI-only interface, no built-in SPC or auto-calibration; requires external MCU for angle computation. | Lacks SENT output and integrated diagnostics; suitable only for non-safety-critical consumer or industrial uses. | Select if cost-sensitive design accepts higher software overhead and lower accuracy (±1.5° typical). |
| TDK-Micronas HAL3900 | 12-bit resolution, Hall-based (not GMR), supports PWM/SENT but no revolution counter; lower temperature range (-40°C to +125°C). | Lower angular precision and no lifetime drift compensation; insufficient for EPS-grade reliability. | Choose only for legacy Hall-system upgrades where magnetic field strength exceeds 40 mT and safety integrity is not required. |
Compared with AMS AS5055A and HAL3900, the TLE5012BE9000XUMA1 uniquely combines SENT-compliant SPC output, 15-bit resolution, on-chip auto-calibration, and AEC-Q100 Grade 0 qualification - making it the only drop-in solution for ASIL-B EPS and SAS systems requiring zero-host computational load and guaranteed lifetime accuracy.

FAQ
What interface protocols does the TLE5012BE9000XUMA1 support out-of-the-box?
This part is factory pre-configured for Short PWM Code (SPC) output compliant with SAE J2716. It does not require register programming to operate in SPC mode. The SSC, PWM, HSM, and IIF interfaces are disabled at power-up unless reconfigured via SSC - which is not possible on E9000 derivates due to fuse-locking of interface settings.
Does the TLE5012BE9000XUMA1 require an external magnet, and what are its specifications?
Yes, it requires an external diametrically magnetized 2-pole ring or bar magnet placed axially or off-axis relative to the sensor. Recommended magnet strength is 20–80 mT at the sensor surface; air gap tolerance is ±0.5 mm. No magnet calibration or alignment routine is needed - the device uses laser-trimmed fuses for initial offset/gain compensation.
How does the auto-calibration function improve long-term accuracy?
The auto-calibration algorithm runs continuously during operation, using statistical analysis of sine/cosine signal amplitudes and offsets across rotation cycles to correct for thermal drift, mechanical stress, and aging effects. When enabled, it maintains total angle error within ±1.0° over -40°C to +150°C and 15+ years of operation - verified per AEC-Q100 accelerated lifetime testing.
Can multiple TLE5012BE9000XUMA1 sensors share the same SPC bus line?
No - unlike SSC or PWM modes, SPC mode does not support bus topology. Each TLE5012BE9000XUMA1 requires a dedicated CSQ line to the host controller because SPC uses asynchronous, self-clocking pulse-width encoding without addressing or arbitration. For multi-sensor systems, separate GPIOs or time-multiplexed polling via SSC (on non-E9000 variants) is required.
