Infineon Technologies TLI493DW2BWA2XTSA1

Overview

TLI493DW2BWA2XTSA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor IC with integrated I²C interface, Wake-Up interrupt capability, and ±160 mT full-scale 3-axis field sensing. It delivers 12-bit X/Y/Z magnetic data plus 10-bit temperature measurement, operates from 2.8 V to 3.5 V, and consumes only 7 nA in power-down mode. It is used in compact motion-sensing applications such as mobile camera lens position control and robotic joint angle detection.

For engineers reviewing the TLI493DW2BWA2XTSA1 datasheet, TLI493DW2BWA2XTSA1 pinout, TLI493DW2BWA2XTSA1 application, or TLI493DW2BWA2XTSA1 equivalent, this page provides verified technical context, validated pin functions, confirmed operating modes (including Wake-Up envelope triggering), real-world use cases, and qualified alternative options for industrial and battery-powered embedded systems.

Technical Context

The TLI493DW2BWA2XTSA1 integrates three orthogonal Hall plates (X, Y, Z) sequentially multiplexed to a tracking ADC, enabling simultaneous 3D field vector acquisition. Its dual-oscillator architecture-comprising a low-power LP-OSC for standby and fast F-OSC for active measurement-enables deterministic wake-up latency and configurable update rates from 0.5 Hz to 1 kHz.

Wake-Up functionality is implemented per axis via programmable upper/lower magnetic thresholds; an /INT pulse is asserted when any axis exceeds its envelope. The I²C slave interface supports clock stretching via /INT–SCL coupling, and register configuration allows runtime switching between continuous, single-shot, and low-power wake-on-field-change modes.

Key Specifications

FAQ

What is the default I²C address for TLI493DW2BWA2XTSA1?

The default 7-bit I²C write address is 0x6A (1010100b), corresponding to read address 0x6B. Address bits A0–A1 are set by factory marking (A2 variant), and cannot be changed in-circuit. No address pins or software-configurable addressing are provided.

Can the /INT pin be disabled or reconfigured as a general-purpose I/O?

No-the /INT pin is a dedicated open-drain output with fixed function: it asserts low upon measurement completion or Wake-Up event. It cannot be disabled, tri-stated, or repurposed as GPIO. Its behavior is controlled solely by register settings for interrupt enable and threshold configuration.

How does the Wake-Up function interact with I²C communication?

During active I²C transactions, the /INT signal is inhibited to prevent bus collisions-a feature called "collision avoidance." Once the transaction completes, pending Wake-Up events are latched and /INT asserts. This ensures reliable interrupt delivery without interfering with data reads/writes.

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

Yes-a 100 nF ceramic capacitor placed as close as possible to the VDD and GND pins is mandatory for stable operation. Larger values (>1 µF) may cause startup delay or oscillation; smaller values (<10 nF) increase susceptibility to supply noise and degrade Wake-Up reliability.
