Infineon Technologies TLE493DW2B6A2HTSA1

Overview

TLE493DW2B6A2HTSA1 from Infineon is a low-power 3D Hall-effect magnetic sensor IC with I²C interface and wake-up functionality, designed for automotive position sensing. It measures magnetic flux density in X/Y/Z axes up to ±160 mT with 12-bit resolution per axis, integrates a 10-bit temperature sensor, and operates from 2.8 V to 3.5 V across -40°C to +125°C junction temperature.

For engineers reviewing the TLE493DW2B6A2HTSA1 datasheet, TLE493DW2B6A2HTSA1 pinout, TLE493DW2B6A2HTSA1 application, or TLE493DW2B6A2HTSA1 equivalent, key selection criteria include its programmable wake-up thresholds per axis, 7 nA typical power-down current, configurable update rates, integrated diagnostics, and PG-TSOP6-6-8 package compatibility with space-constrained automotive modules.

Technical Context

The TLE493DW2B6A2HTSA1 implements three orthogonal Hall plates (X/Y/Z) sequentially multiplexed to a successive-approximation ADC, enabling simultaneous 3D field vector measurement. Its power mode control unit includes both low-power oscillator (LP-OSC) and fast oscillator (F-OSC), supporting dynamic transition between ultra-low-power sleep (7 nA) and active measurement cycles.

Wake-up functionality operates independently per axis using user-configurable upper/lower magnetic thresholds; an /INT open-drain interrupt signal is asserted when any axis exceeds its envelope. The I²C slave interface supports four default address options (F0H/F1H for this variant), with collision avoidance logic preventing spurious interrupts during bus transactions.

FAQ

What is the default I²C address for TLE493DW2B6A2HTSA1?

The TLE493DW2B6A2HTSA1 uses F0H (write) / F1H (read) as its factory-programmed I²C address, corresponding to the "A2" variant in Infineon's ordering matrix. This address is fixed and cannot be changed via software or hardware pins, ensuring predictable bus initialization in multi-sensor systems.

How does the wake-up function operate across X/Y/Z axes?

The wake-up function independently monitors each axis against user-configurable upper and lower magnetic thresholds. An /INT interrupt is generated if any axis exceeds its envelope, with logical OR combining all three channels. Interrupts are suppressed during I²C transactions to prevent bus collisions, and threshold values are stored in non-volatile configuration registers.

Can the TLE493DW2B6A2HTSA1 measure temperature, and how is it used?

Yes, it integrates a 10-bit temperature sensor that measures die temperature during each measurement cycle, immediately after X/Y/Z Hall readings. The temperature value is accessible via I²C register read and is used internally for sensor compensation; it can also serve as a system thermal monitor in space-constrained modules where adding a discrete sensor is impractical.

Is the PG-TSOP6-6-8 package RoHS and AEC-Q100 qualified?

Yes, the PG-TSOP6-6-8 package for TLE493DW2B6A2HTSA1 is RoHS-compliant and qualified to AEC-Q100 Grade 0 (−40°C to +125°C), with full traceability, humidity sensitivity level (HSL) rating, and automotive-specific reliability testing including HTOL, TC, and ESD per JS-001 and JESD22-C101 standards.
