Infineon Technologies TLI493DW2BWA3XTSA1

Overview

TLI493DW2BWA3XTSA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor with integrated I²C interface, Wake-Up interrupt capability, ±160 mT full-scale 3-axis field sensing, 12-bit resolution per axis, and 7 nA typical power-down current. It operates from 2.8 V to 3.5 V over –40°C to +125°C and supports X-Y angular measurement for compact rotary position sensing in space-constrained consumer and industrial systems.

For engineers reviewing the TLI493DW2BWA3XTSA1 datasheet, TLI493DW2BWA3XTSA1 pinout, TLI493DW2BWA3XTSA1 application, or TLI493DW2BWA3XTSA1 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in end-of-shaft angle sensing and mobile lens actuation, and confirmed alternative parts with documented electrical and functional distinctions.

Technical Context

The TLI493DW2BWA3XTSA1 integrates three orthogonal Hall plates (X/Y/Z), a successive-approximation ADC, temperature sensor, low-power oscillator (LP-OSC), fast oscillator (F-OSC), and I²C register interface. Its power mode control enables dynamic switching between ultra-low-power sleep (7 nA) and active measurement cycles with configurable update rates.

Wake-Up functionality uses independent upper/lower thresholds per axis to generate an open-drain /INT pulse when field changes exceed envelope limits - supporting system-level power gating. The /INT pin may be wired to SCL for clock stretching or used as a dedicated interrupt signal, with collision avoidance logic preventing spurious triggers during I²C transactions.

Key Specifications

Pinout & Package

TLI493DW2BWA3XTSA1 uses the SG-WFWLB-5-2 wafer-level chip-scale package (WLCSP), a 5-pin, 0.4 mm pitch, bottom-terminal package with exposed die and no wire bonds - optimized for minimal footprint and high thermal conductivity in thermally dense assemblies.

FAQ

What is the default I²C address for TLI493DW2BWA3XTSA1?

The default I²C write address is 0x88H and read address is 0x89H, corresponding to marking code "A3" on the device. This address is hardwired and cannot be changed via software; alternate versions (A0–A2) offer different fixed addresses (0x6A/0x6B, 0x44/0x45, 0xF0/0xF1) for multi-sensor bus configurations.

Can the /INT pin be used simultaneously as both interrupt output and I²C clock line?

Yes - the /INT pin supports I²C clock stretching when externally connected to the SCL line. In this configuration, the sensor holds SCL low after data transmission to extend the clock cycle, allowing time for internal processing before the next byte. This eliminates the need for a separate interrupt GPIO and reduces MCU pin count.

How does the Wake-Up function operate across X, Y, and Z axes?

The Wake-Up function independently compares each axis (X/Y/Z) against user-programmable upper and lower thresholds. An interrupt (/INT) is asserted if any axis exceeds its envelope - the /INT output is the logical OR of all three channel comparisons. Thresholds are stored in dedicated registers and can be updated dynamically via I²C without resetting the device.

Is external decoupling capacitor C1 mandatory, and what value is recommended?

Yes - a 100 nF ceramic capacitor (C1) is mandatory and must be placed as close as possible to the VDD and GND pins. This minimizes supply noise coupling into the sensitive analog Hall front-end. Longer traces increase inductance and degrade measurement stability; ferromagnetic capacitors must be avoided due to magnetic interference with the Hall elements.
