Product details
Overview
TLE5014C16DXUMA1 from Infineon is a dual-die GMR-based absolute angle sensor with SPC interface, delivering two independent 12-bit angular outputs (0°–360°) with ≤1° total error over −40°C to +125°C, EEPROM-configurable zero angle and customer ID, and ASIL-D compliance per ISO 26262 for automotive steering and throttle position sensing.
For engineers reviewing the TLE5014C16DXUMA1 datasheet, TLE5014C16DXUMA1 pinout, TLE5014C16DXUMA1 application, or TLE5014C16DXUMA1 equivalent, key selection criteria include dual-channel functional safety architecture, SPC interface timing (2.5 µs unit time), galvanic isolation between dies, 32-point magnetic error correction, and preconfigured SPC ID/rolling counter/CRC settings.
Technical Context
The TLE5014C16DXUMA1 integrates two physically flipped GMR sensor dies in one PG-TDSO-16 package, generating complementary rotation-direction outputs to enable cross-checking for fault detection. Each die operates independently with dedicated VDD/GND and I/O pins, and internal safety mechanisms achieve >97% diagnostic coverage per channel.
Its SPC interface is factory-locked to 2.5 µs unit time, 5UT low time, constant 90UT trigger, enabled short serial message, and rolling counter in CRC-parameters unchangeable without Infineon authorization to maintain ASIL-D safety case integrity.

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 |
|---|---|---|---|
| AS5055A-DSOT | Single-die, SPI-only interface, no EEPROM, 14-bit resolution, ASIL-B rated | Lacks dual-die redundancy and ASIL-D certification; suitable for non-safety-critical HVAC dampers | Select only if ASIL-D is not required and SPI interface aligns with existing MCU peripherals |
| TLE5012BE1500 | Single-die, SENT/PWM/SPC configurable (not locked), 15-bit resolution, same PG-TDSO-16 package | Requires external safety mechanisms to reach ASIL-D; lacks factory-locked SPC configuration | Choose when flexible interface selection and higher resolution outweigh certified SPC determinism |
Compared with AS5055A-DSOT and TLE5012BE1500, the TLE5014C16DXUMA1 delivers guaranteed ASIL-D compliance through its dual-die architecture and factory-locked SPC interface-eliminating runtime configuration risks and reducing safety case validation effort in EPS and brake-by-wire systems.

FAQ
Is the SPC interface on TLE5014C16DXUMA1 reconfigurable?
No. The SPC interface parameters-including 2.5 µs unit time, 90UT trigger, rolling counter in CRC, and SPC ID-are factory-locked during production. Any modification requires Infineon authorization and invalidates the ASIL-D safety case, making reconfiguration unsuitable for certified automotive applications.
How does the dual-die architecture improve functional safety?
The top and bottom GMR dies are physically flipped, causing opposite rotation-direction responses to the same magnetic field. This inherent divergence enables continuous plausibility checking between channels-detecting stuck-at, drift, or magnetic interference faults without external logic or additional sensors.
What is the role of the 32-point lookup table (LUT)?
The on-chip 32-point LUT corrects systematic angle errors caused by magnetic circuit asymmetries (e.g., magnet placement, yoke geometry). It operates autonomously during measurement, applying calibrated offsets before output-reducing host MCU computational load and improving real-time accuracy.
Can TLE5014C16DXUMA1 operate with a single power supply rail?
Yes, but both VDD-1 and VDD-2 must be supplied from the same 4.5–5.5 V source, and both GND-1 and GND-2 must connect to the same ground plane. While galvanically isolated internally, shared supply simplifies PCB layout while preserving fault containment via independent current paths and diagnostics.
