Infineon Technologies TLE5014P16XUMA1

Overview

TLE5014P16XUMA1 from Infineon Technologies is a GMR-based automotive angle sensor delivering 360° absolute angular position measurement with ≤1° total error over -40°C to +125°C, 12-bit resolution (0.0879°/LSB), and PWM interface output. It integrates EEPROM for zero-angle calibration and customer ID programming, supports ASIL-D functional safety per ISO 26262, and targets steering angle sensing in EPS systems.

For engineers reviewing the TLE5014P16XUMA1 datasheet, TLE5014P16XUMA1 pinout, TLE5014P16XUMA1 application, or TLE5014P16XUMA1 equivalent, this page provides verified technical context, interface timing constraints, magnetic field operating range (33–50 mT), safety mechanism coverage (SPFM > 97%), and package-specific layout guidance for PG-TDSO-16.

Technical Context

The TLE5014P16XUMA1 implements a dual-bridge GMR sensing element with on-chip SD-ADCs for X/Y magnetic field component digitization, followed by hardware CORDIC computation to derive absolute angle. Its internal PMU supplies three isolated rails (VRS, VRA, VRD) directly from VDD, enabling robust operation under reverse polarity and load dump conditions.

Functional safety is enforced via redundant monitoring paths: ISM_SAF handles safety-critical fault detection (e.g., ADC saturation, clock failure), while ISM_ALG executes real-time offset/temperature drift compensation using a 32-point LUT. The PWM interface outputs a duty-cycle-modulated signal (10%–90%) with fixed 2.5 ms period and ±1.5 µs jitter, synchronized to internal PLL timing.

FAQ

What is the maximum allowable magnetic field strength for reliable operation?

The TLE5014P16XUMA1 operates reliably within a magnetic field range of 33 mT to 50 mT across its full temperature range (-40°C to +125°C). Field strengths outside this band cause increased angle error or saturation; design must ensure magnet placement and air gap maintain flux density within these limits per Figure 3-1 in the datasheet.

How is zero-angle calibration performed and stored?

Zero-angle offset is programmed via the SICI interface during end-of-line calibration and permanently stored in on-chip EEPROM. The device retains this value across power cycles and supports reprogramming; the 112-bit customer ID is also written to EEPROM for traceability and anti-counterfeiting.

Does the PWM output require an external pull-up resistor?

Yes-the OUT pin is an open-drain N-channel driver. A 4.7 kΩ pull-up resistor to VDD is required to establish the logic-high level. The datasheet specifies 20 mA sink capability, allowing direct interfacing with standard 5 V microcontrollers without level-shifting.

Can the TLE5014P16XUMA1 be used with SENT or SPC interfaces?

No-TLE5014P16XUMA1 is the PWM-interface derivative. SENT and SPC functionality are implemented in separate part numbers (TLE5014S16 and TLE5014C16), differentiated by factory-programmed interface logic and pin-strapping. Hardware interface selection is fixed at manufacture and not reconfigurable in the field.
