Product details
Overview
TLE5014P16DXUMA1 from Infineon Technologies is a dual-die GMR-based absolute angle sensor in PG-TDSO-16 package, delivering two independent 12-bit PWM-encoded angle outputs with ≤1° total error over −40°C to +125°C, ASIL-D compliance per ISO 26262, and integrated EEPROM for zero-angle calibration-used in automotive electric power steering (EPS) and transmission position sensing.
For engineers reviewing the TLE5014P16DXUMA1 datasheet, TLE5014P16DXUMA1 pinout, TLE5014P16DXUMA1 application, or TLE5014P16DXUMA1 equivalent, key selection criteria include dual-channel functional safety architecture, PWM interface lock (200 Hz, 12.5–87.5% duty cycle), galvanic isolation between dies, 112-bit programmable customer ID, and 32-point magnetic error correction LUT.
Technical Context
The TLE5014P16DXUMA1 integrates two physically flipped GMR sensor dies in one package, generating complementary angular outputs to enable cross-channel fault detection; each die operates independently with dedicated VDD/GND pairs and isolated interface pins.
Its PWM interface is factory-locked at 200 Hz with fault indication via 5%/95% duty cycle edges and BIST/reset status encoding; internal safety mechanisms achieve >97% diagnostic coverage per channel, supported by EEPROM-stored configuration including ANG_BASE register for output alignment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Resolution | 12-bit absolute value → 0.0879° step size for precise rotor positioning |
| Angle Accuracy | ≤1° max error over full temp range → meets ASIL-D torque-sensing requirements |
| PWM Interface | Fixed 200 Hz, 12.5–87.5% duty cycle → compatible with standard automotive PWM ADC inputs |
| Functional Safety | ISO 26262 ASIL-D compliant with >97% DC per channel → enables single-chip safety-critical systems |
| Operating Temp | −40°C to +125°C ambient → qualified for under-hood EPS and gearbox applications |
| EEPROM Capacity | Stores zero-angle offset, customer ID (112-bit), and LUT coefficients → enables field calibration and traceability |
| Magnetic Principle | Giant Magneto Resistance (GMR) → high signal-to-noise ratio and immunity to stray fields |
Pinout & Package
PG-TDSO-16 thermally enhanced leadframe package with MSL 3 rating, halogen-free, RoHS-compliant, and 45 K/W junction-to-case thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | IF1/IF2 Address Inputs | Hardwired to GND for PWM mode; disable bus programming to enforce interface lock |
| 3, 14 | IF3 Input | Connect to IFC to enable address coding; unused in PWM configuration |
| 4, 13 | VDD-1 / VDD-2 | Independent supply rails for each die → supports dual-power domain fault containment |
| 5, 12 | GND-1 / GND-2 | Galvanically isolated ground returns → prevent common-mode coupling between channels |
| 6, 11 | IFA-1 / IFA-2 | Internally connected to GND → stabilize internal reference during PWM operation |
| 7, 10 | IFB-1 / IFB-2 | PWM output pins (push-pull) → drive standard 5V automotive PWM receivers without external pull-up |
| 8, 9 | IFC-1 / IFC-2 | Address output pins → tied to IF3 to complete bus-mode circuit; inactive in PWM mode |
Key Features
| Feature | Design Value |
|---|---|
| Dual flipped-GMR dies | Opposite rotation sensing per die → intrinsic plausibility check without external logic |
| Factory-locked PWM interface | No runtime reconfiguration possible → ensures deterministic timing and safety analysis validity |
| 32-point LUT correction | Compensates systematic magnetic nonlinearity (e.g., stator asymmetry) → eliminates need for external calibration |
| 112-bit programmable ID | Enables unique device identification and firmware binding → supports secure OTA updates and recall tracking |
| Redundant safety mechanisms | Independent watchdogs, memory CRC, and analog path diagnostics → achieves >97% single-point fault coverage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5055A-DSOT | Single-die Hall-based sensor with SPI output; no built-in EEPROM or ASIL-D certification | Lacks dual-die redundancy and functional safety documentation; requires external safety MCU | Select only for non-safety-critical industrial rotary encoders |
| TLE5012B E16XUMA1 | Single-die GMR sensor with SENT/PWM selectable interface; no second die or cross-die diagnostics | Provides half the safety coverage; suitable for ASIL-B systems where cost outweighs redundancy needs | Choose when footprint and cost constraints preclude dual-die solution but GMR performance is required |
Compared with AS5055A-DSOT and TLE5012B E16XUMA1, the TLE5014P16DXUMA1 uniquely delivers certified ASIL-D readiness through hardware-redundant dies, factory-locked PWM, and on-chip diagnostics-making it the only option for single-package EPS or brake-by-wire angle sensing without external safety co-processors.

FAQ
Is the PWM interface reconfigurable to SENT or SPC after purchase?
No. The TLE5014P16DXUMA1 has a factory-locked PWM interface; register settings for SENT or SPC modes are disabled and inaccessible. This lock ensures deterministic behavior required for ISO 26262 ASIL-D compliance and prevents field misconfiguration that could compromise safety mechanisms.
How is dual-die redundancy implemented physically and electrically?
The two GMR dies are mounted in flipped orientation within the same PG-TDSO-16 package, with separate VDD/GND pairs and isolated IFB interface pins. Their outputs exhibit opposite rotation direction by default, enabling real-time plausibility checking without external logic or software intervention.
What is the role of the 32-point look-up table (LUT)?
It stores pre-calculated correction coefficients to compensate for systematic magnetic nonlinearity caused by mechanical tolerances in the magnetic circuit (e.g., magnet placement, stator geometry). The LUT is applied in real time during angle computation, eliminating post-production calibration steps.
Does the device support dynamic zero-angle adjustment during operation?
Yes. The ANG_BASE register in EEPROM allows runtime reprogramming of the zero-angle offset via the IFB pin using the SICI protocol, enabling field calibration without disassembly-though this requires temporary access to bus mode, which is disabled in default PWM operation.
