Product details
Overview
TLE5014S16DXUMA1 from Infineon Technologies is a dual-die GMR-based absolute angle sensor in PG-TDSO-16 package, delivering two independent 12-bit SENT-encoded angular outputs with ≤1° total error over −40°C to +125°C, ASIL-D compliance per ISO 26262, and integrated EEPROM for zero-angle calibration and 112-bit customer ID storage - used in automotive electric power steering (EPS) and transmission position sensing.
For engineers reviewing the TLE5014S16DXUMA1 datasheet, TLE5014S16DXUMA1 pinout, TLE5014S16DXUMA1 application, or TLE5014S16DXUMA1 equivalent, key selection criteria include SENT interface lock, dual-channel redundancy architecture, galvanic isolation between dies, 32-point magnetic error correction LUT, and functional safety diagnostic coverage >97% per channel.
Technical Context
The device integrates two physically flipped GMR sensor dies in one package, generating opposite rotation-direction outputs by default - enabling cross-checking for fault detection in safety-critical systems. Each die operates independently with dedicated VDD/GND and SENT I/O (IFB-1/IFB-2), and shares no electrical connection beyond common package substrate.
SENT interface is factory-locked to SAE J2716-2010 Single Secure Sensor mode with 3.0 µs unit time, 5UT low time, pause pulse enabled, and error code 4091 for fault indication. Configuration is stored in on-chip EEPROM and cannot be altered post-manufacture without Infineon authorization.

Applications
| Electric Power Steering (EPS) | Transmission Gear Position Sensing |
|---|---|
Use Scenario: Real-time measurement of steering column rotation angle for assist torque calculation and feedback control. IC Role / Device Role / Timing Role: Primary dual-channel angle sensor providing redundant SENT outputs to EPS ECU for ASIL-D-compliant position estimation.

Use Scenario: Closed-loop position feedback for electro-hydraulic brake actuator cam or piston rotation. IC Role / Device Role / Timing Role: Safety-critical angle monitor delivering two independent SENT streams to separate safety channels in brake ECU. Use Value: Diagnostic coverage >97% per channel satisfies ASIL-D FMEDA requirements; 112-bit programmable ID enables traceability in production and field diagnostics. | Use Scenario: High-fidelity column angle capture for steer-by-wire control algorithms requiring sub-degree resolution and fault tolerance. IC Role / Device Role / Timing Role: Dual-die GMR sensor supplying anti-phase outputs that are software-aligned using ANG_BASE register to deliver identical angle values. Use Value: Flipped die orientation enables intrinsic plausibility check; 32-point LUT corrects for magnetic hysteresis in compact steering column assemblies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel GMR angle sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMS AS5055A-DSO | Single-die, SPI/I²C interface, no SENT output, no ASIL-D certification | Lacks dual-die redundancy and functional safety documentation; suitable for non-safety EPS auxiliary sensing | Select only for non-ASIL systems where SENT interface and dual-die fault tolerance are not required |
| TDK-Micronas HAL3900 | Single-channel SENT output, no dual-die architecture, lower diagnostic coverage (~90%), no EEPROM-based LUT | Used in cost-sensitive throttle/pedal position sensing; not validated for ASIL-D EPS or transmission use | Choose when single-channel SENT suffices and system-level redundancy is implemented externally |
Compared with AMS AS5055A-DSO and TDK-Micronas HAL3900, TLE5014S16DXUMA1 uniquely delivers certified ASIL-D dual-die redundancy in a single SENT-enabled package, eliminating need for external cross-check logic or secondary sensors in high-integrity automotive motion control.

FAQ
Can the SENT interface configuration of TLE5014S16DXUMA1 be changed after purchase?
No. The SENT interface is factory-locked to SAE J2716-2010 Single Secure Sensor mode with fixed parameters: 3.0 µs unit time, 5UT low time, pause pulse enabled, and error code 4091. These settings are immutable without Infineon's authorized reprogramming procedure, which is not supported for standard production units.
How is dual-die redundancy implemented physically in the PG-TDSO-16 package?
The package contains two separate GMR sensor dies mounted in flipped orientation - top die (pins 1–8) and bottom die (pins 9–16) - with no shared electrical connections except the package substrate. Their magnetic axes are rotated 180° relative to each other, producing inherently opposite angle outputs unless corrected via EEPROM ANG_BASE register.
What is the role of the 32-point look-up table in TLE5014S16DXUMA1?
The 32-point LUT is stored in EEPROM and applied per-channel to correct systematic angle errors caused by magnetic circuit non-idealities (e.g., flux leakage, yoke asymmetry). It operates in real time during SENT frame generation and is fully programmable during calibration - enabling <±0.5° residual error after correction.
Does TLE5014S16DXUMA1 support both channels outputting identical angle values?
Yes, but only via EEPROM configuration. By writing to the ANG_BASE register, the rotation direction and zero-offset of one channel can be inverted and aligned to match the other. This alignment is performed during system calibration and does not affect the inherent physical anti-phase relationship of the raw sensor outputs.
