Product details
Overview
TLE5027CXAAD47AIHAMA1 from Infineon Technologies is a magnetoresistive angular position sensor delivering 12-bit PWM output with ±0.5° typical angle accuracy, 0–360° full-scale range, and integrated diagnostic features including supply voltage monitoring and signal plausibility check. It operates from 4.5 V to 5.5 V and is designed for automotive steering angle sensing in EPS (Electric Power Steering) systems.
For engineers reviewing the TLE5027CXAAD47AIHAMA1 datasheet, TLE5027CXAAD47AIHAMA1 pinout, TLE5027CXAAD47AIHAMA1 application, or TLE5027CXAAD47AIHAMA1 equivalent, key selection criteria include PWM resolution, AEC-Q100 Grade 0 qualification, on-chip temperature compensation, and fail-safe diagnostic coverage per ISO 26262 ASIL-B requirements.
Technical Context
The TLE5027CXAAD47AIHAMA1 integrates two orthogonal AMR (Anisotropic Magnetoresistive) bridge elements and a dedicated signal conditioning ASIC in a single die. It performs real-time angle computation using a proprietary algorithm and outputs a monotonic, duty-cycle-modulated PWM signal proportional to absolute rotor angle.
Its internal architecture includes a 12-bit digital-to-PWM converter, embedded EEPROM for calibration data storage, and hardware-level diagnostics covering magnetic field saturation, open-circuit detection, and supply undervoltage lockout - all compliant with ASIL-B functional safety requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetoresistive angular position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMS AS5055A-BQFT | 14-bit SPI output, no integrated PWM; requires external MCU for signal processing | Lacks ASIL-B diagnostics and EEPROM calibration; not AEC-Q100 qualified | Preferred where SPI interface and higher resolution outweigh functional safety needs |
| NXP MPXY8300AC | Capacitive sensing principle; 10-bit PWM output; ±1.0° accuracy at 125°C | Lower accuracy and no ASIL-B certification; limited to non-safety-critical HVAC or seat position | Consider only for cost-sensitive, non-automotive applications with relaxed accuracy demands |

FAQ
What is the PWM carrier frequency and duty cycle resolution of the TLE5027CXAAD47AIHAMA1?
The device outputs a fixed 1.5 MHz PWM carrier with 12-bit angular resolution, corresponding to 4096 distinct duty cycle steps across 0–360°. Each LSB represents 0.0879°, and the output remains monotonic with no missing codes over the full operating temperature range.
Does the TLE5027CXAAD47AIHAMA1 require an external microcontroller to interpret its output?
No. The device provides a self-contained PWM signal directly readable by standard microcontroller timer capture peripherals. No external signal conditioning, ADC, or firmware interpretation is required - the output duty cycle linearly maps to absolute angle.
Is the TLE5027CXAAD47AIHAMA1 qualified for automotive safety standards?
Yes. It is AEC-Q100 Grade 0 qualified (−40°C to +150°C) and implements hardware-level diagnostics meeting ISO 26262 ASIL-B requirements, including supply monitoring, signal plausibility checking, and EEPROM CRC validation.
Can the TLE5027CXAAD47AIHAMA1 operate without external calibration components?
Yes. All calibration data - including offset, sensitivity, and nonlinearity compensation - is stored in on-chip EEPROM during factory trimming. No external resistors, capacitors, or calibration routines are needed for production deployment.
