Product details

Overview

TLE493DW2B6A0HTSA1 from Infineon is a low-power 3D Hall sensor IC for automotive position sensing, delivering ±160 mT magnetic field measurement in X/Y/Z axes with 12-bit resolution per axis and integrated 10-bit temperature sensing. It operates from 2.8 V to 3.5 V over -40°C to +125°C and features I²C interface (default address 0x6A/0x6B), wake-up interrupt (/INT), and 7 nA typ. power-down current. Used in gear stick and steering column control modules.

For engineers reviewing the TLE493DW2B6A0HTSA1 datasheet, TLE493DW2B6A0HTSA1 pinout, TLE493DW2B6A0HTSA1 application, or TLE493DW2B6A0HTSA1 equivalent, key selection criteria include 3D angular measurement capability, configurable wake-up thresholds per axis, diagnostic self-test coverage of analog/digital/Hall elements, and TSOP6-6-8 package compatibility with space-constrained automotive PCB layouts.

Technical Context

The TLE493DW2B6A0HTSA1 integrates three orthogonal Hall plates (X/Y/Z), a successive-approximation ADC, programmable wake-up comparators per axis, and an I²C slave interface with open-drain SDA/SCL pins. Its power mode control includes dual oscillators (fast and low-power) and undervoltage detection to ensure reliable restart under supply transients.

Each measurement cycle sequentially samples all three Hall channels plus temperature by default; wake-up interrupts are generated when any axis exceeds its user-defined upper/lower threshold envelope, with logical OR combining across axes. The /INT pin is open-drain and can be inhibited during I²C transactions via collision avoidance.

Key Specifications

Parameter	Value and Actual Design Meaning
Magnetic Range	±160 mT per axis - supports robust position sensing in high-stray-field environments like transmission housings.

3: GND	Ground reference	Second ground pin reduces impedance in high-frequency switching paths.
4: VDD	Supply voltage input	Single 2.8–3.5 V supply powers all analog/digital blocks and internal biasing.
5: GND	Ground reference	Third ground pin enhances return path integrity for Z-axis Hall plate.
6: SDA	I²C bidirectional data line	Open-drain interface supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C timing.

Key Features

Feature	Design Value
X-Y angular measurement mode	Enables contactless rotation sensing without mechanical wear, supporting multi-function knob UIs.
Integrated diagnostics	Verifies functionality of digital logic, analog front-end, and Hall probes independently-supports ASIL-B functional safety goals.
Configurable update frequency	Allows dynamic trade-off between latency (up to 100 Hz) and power consumption in real-time control loops.
Wake-up threshold per axis	Per-channel upper/lower limits reduce false triggers from cross-axis interference in 3D field environments.
Temperature compensation	On-chip 10-bit sensor enables real-time gain/offset correction of Hall outputs across full operating range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3D Hall position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90393EDC-ABB-000-TU	Tri-axis Hall with SPI interface, 16-bit resolution, ±50 mT range, 1.71–3.6 V supply	Lacks integrated wake-up comparator; requires external interrupt logic for low-power wake events	Select when higher resolution and SPI compatibility outweigh need for autonomous wake-up capability
AK09973N	3D Hall sensor with I²C, ±2400 µT range, 16-bit output, no built-in diagnostics or wake-up function	Optimized for compass/navigation; lacks automotive qualification and temperature-compensated Hall biasing	Prefer for consumer electronics where extended magnetic range matters more than functional safety compliance

Compared with MLX90393 and AK09973N, the TLE493DW2B6A0HTSA1 uniquely combines automotive-grade diagnostics, per-axis wake-up thresholds, and ultra-low 7 nA sleep current-making it the only option qualified for ASIL-B–compliant position sensing in powertrain and chassis systems.

FAQ

What is the default I²C address for TLE493DW2B6A0HTSA1?

The TLE493DW2B6A0HTSA1 uses fixed I²C addresses: 0x6A for write operations and 0x6B for read operations. This corresponds to the A0 variant marked "A0" on the device body and documented in Infineon's ordering information table. No configuration register changes this address.

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

The wake-up function monitors each axis independently using user-programmable upper and lower thresholds. An interrupt (/INT) is asserted when any axis exceeds its envelope; the signal is the logical OR of all three channel comparisons. Interrupt generation is disabled during active I²C transactions to prevent bus collisions.

Is the temperature sensor calibrated and usable for system-level compensation?

Yes-the integrated 10-bit temperature sensor is factory-calibrated and provides absolute junction temperature readings with ±2.5°C accuracy over -40°C to +125°C. Its output is accessible via dedicated I²C registers and is used internally for Hall offset/gain compensation.

What grounding configuration is required for optimal noise immunity?

The TLE493DW2B6A0HTSA1 has three dedicated GND pins (pins 2, 3, and 5) to minimize ground loop impedance. For best performance, connect all three to a solid, low-impedance ground plane using short traces; avoid daisy-chaining or shared ground vias with noisy digital circuits.
