Product details
Overview
TLE493DP2B6A3HTSA1 from Infineon 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, <1.5% total error over temperature (–40°C to +150°C), and integrated temperature compensation. Used in automotive throttle pedal and steering angle sensing where high-precision angular reconstruction is required.
For engineers reviewing the TLE493DP2B6A3HTSA1 datasheet, TLE493DP2B6A3HTSA1 pinout, TLE493DP2B6A3HTSA1 application, or TLE493DP2B6A3HTSA1 equivalent, key selection criteria include 3D field resolution, I²C address configurability (0x2A/0x2B), built-in self-test (BIST), ASIL-B compliance per ISO 26262, and stray-field immunity up to ±5 mT offset.
Technical Context
This sensor implements three orthogonal Hall plates with chopper-stabilized amplifiers and sigma-delta ADCs per channel, enabling real-time vector field computation. Its digital signal processing core performs on-chip temperature compensation, offset correction, and sensitivity calibration across the full operating range.
The device supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C communication with configurable alert pin for field threshold violation detection. It operates from a single 3.3 V supply with typical current consumption of 2.8 mA in active mode and 1.2 µA in power-down mode.
Key Specifications

FAQ
What is the maximum I²C clock frequency supported by TLE493DP2B6A3HTSA1?
The device supports Fast-mode I²C up to 400 kHz, with guaranteed timing margins across –40°C to +150°C. It does not support Fast-mode Plus (1 MHz) or High-speed mode. The SCL rise/fall time must remain ≤300 ns, and bus capacitance must be ≤400 pF for reliable operation.
Does TLE493DP2B6A3HTSA1 require external EEPROM or calibration data storage?
No. All factory-trimmed calibration coefficients (offset, sensitivity, temperature coefficients) are stored in on-chip OTP memory and automatically applied during power-up. No external memory or host-side calibration routines are needed for basic operation.
How is the INT pin used for functional safety monitoring?
The INT pin asserts low on configurable events: field threshold violation, internal BIST failure, CRC error in register read, or power-on reset timeout. Its status is latched until cleared via I²C command, enabling ECU-level fault logging and fail-safe state transitions per ISO 26262.
Can TLE493DP2B6A3HTSA1 operate with magnets other than diametrically magnetized ring magnets?
Yes. It supports any static or quasi-static magnetic field geometry - including axial, radial, and multipole configurations - as long as the field vector at the sensor location falls within ±10 mT per axis. Performance validation data exists for disc magnets, bar magnets, and custom pole pieces used in pedal and flap mechanisms.
