Infineon Technologies TLE493DP2B6A0HTSA1

Overview

TLE493DP2B6A0HTSA1 from Infineon Technologies is a 3D magnetic position sensor IC based on integrated Hall-effect technology, delivering simultaneous X/Y/Z-axis field measurement with 12-bit digital output via I²C interface. It features ±10 mT full-scale range per axis, 1.8–3.6 V supply operation, and AEC-Q100 Grade 0 qualification (−40°C to +170°C). Used in automotive throttle valve angle sensing and EPS rotor position feedback.

For engineers reviewing the TLE493DP2B6A0HTSA1 datasheet, TLE493DP2B6A0HTSA1 pinout, TLE493DP2B6A0HTSA1 application, or TLE493DP2B6A0HTSA1 equivalent, key selection criteria include 3D field resolution, I²C address configurability, integrated temperature compensation, stray-field immunity up to ±5 mT, and ASIL-B ready diagnostic capability per ISO 26262.

Technical Context

This sensor integrates three orthogonal Hall plates with low-noise signal conditioning, 12-bit ADCs, and digital post-processing including cross-axis sensitivity correction and offset drift compensation. Its internal state machine supports programmable measurement modes (single-shot, periodic, wake-up), configurable I²C addresses (0x2A/0x2B/0x2C), and hardware interrupt generation on field threshold crossing.

The device implements built-in diagnostics: supply voltage monitoring, I²C communication CRC, memory integrity check, and magnetic field plausibility validation. All functions are designed for SEooC integration into ASIL-B systems without requiring external safety mechanisms.

FAQ

What is the maximum I²C clock frequency supported by TLE493DP2B6A0HTSA1?

The device supports Fast-mode Plus I²C operation up to 1 MHz. This allows rapid field data acquisition-up to 1000 full 3D samples per second-with minimal bus overhead. The internal timing controller ensures setup/hold compliance across voltage and temperature extremes, and the SDA/SCL pins include slew-rate limiting to reduce EMI in noisy automotive environments.

Does TLE493DP2B6A0HTSA1 require external calibration for accurate angle measurement?

No external calibration is required. The sensor includes factory-trimmed offset and sensitivity coefficients stored in OTP memory, plus on-the-fly temperature compensation using its integrated die thermometer. Users only need to apply a single-point mechanical alignment during assembly; full 3D field-to-angle mapping is handled internally via preloaded lookup tables and linear interpolation.

How does the INT pin behave during diagnostic fault conditions?

The INT pin asserts low for all detected faults-including supply undervoltage, I²C CRC error, memory checksum failure, or magnetic field plausibility violation-and remains asserted until cleared via I²C register write or power cycle. The fault type is encoded in the STATUS register, allowing software to distinguish between safety-critical events (e.g., memory corruption) and recoverable warnings (e.g., transient overtemperature).

Can TLE493DP2B6A0HTSA1 operate with a 5 V microcontroller I²C bus?

No-it requires level-shifting. The SDA and SCL pins are strictly 3.6 V tolerant and lack internal 5 V-tolerant buffers. Direct connection to a 5 V I²C master will damage the interface. A bidirectional level shifter (e.g., TXS0102) must be used, and the VDD supply must remain within 1.8–3.6 V regardless of bus voltage.
