Infineon Technologies TLE493DW2B6A0HTSA2

Overview

TLE493DW2B6A0HTSA2 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 TLE493DW2B6A0HTSA2 datasheet, TLE493DW2B6A0HTSA2 pinout, TLE493DW2B6A0HTSA2 application, or TLE493DW2B6A0HTSA2 equivalent, key selection criteria include its 7 nA power-down current, programmable wake-up thresholds per axis, X-Y angular measurement mode, integrated diagnostics for analog/digital/Hall probe validation, and PG-TSOP6-6-8 package compatibility with space-constrained automotive modules.

Technical Context

The TLE493DW2B6A0HTSA2 implements three vertically and laterally oriented Hall plates multiplexed into a successive-approximation ADC, enabling simultaneous 3D field vector acquisition. Its power mode control includes dual oscillators (low-power and fast) and undervoltage detection, supporting dynamic reconfiguration without reset.

Wake-up logic compares each axis' magnetic reading against independently programmable upper/lower thresholds; an open-drain /INT signal asserts on any threshold breach. The I²C slave interface supports configurable addresses (default 0x6A/0x6B write/read), collision avoidance during transactions, and interrupt-driven data readout to minimize host polling overhead.

FAQ

What is the default I²C address for TLE493DW2B6A0HTSA2?

The default write address is 0x6A and read address is 0x6B, corresponding to the A0 variant marked on the device. This is fixed by internal bond option and cannot be changed via software configuration. Address conflicts are avoided by selecting variants A1–A3, which offer 0x44/0x45, 0xF0/F0x1, and 0x88/0x89 respectively.

How does the wake-up function operate without MCU intervention?

The wake-up circuit monitors all three magnetic axes continuously in hardware, comparing each against independently programmable upper and lower thresholds. When any axis breaches its envelope, the open-drain /INT pin pulls low-waking the MCU from sleep without requiring active polling or firmware execution. Collision avoidance disables /INT during I²C transactions to prevent spurious interrupts.

Can the TLE493DW2B6A0HTSA2 measure temperature independently of magnetic sensing?

Yes-the integrated 10-bit temperature sensor operates autonomously and can be read at any time via I²C register access (address 0x0C–0x0D). It is sampled automatically after each 3D magnetic measurement cycle by default, but can also be triggered separately or disabled to reduce latency and power consumption in purely magnetic applications.

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

Yes-the PG-TSOP6-6-8 package is RoHS-compliant and the TLE493DW2B6A0HTSA2 is qualified per AEC-Q100 Grade 0 (–40°C to +150°C ambient) for automotive use. The device meets stress test requirements including HTOL, TC, UHAST, and ESD (±2 kV HBM, ±0.75 kV CDM corner pins), with full qualification documentation available from Infineon upon request.
