Infineon Technologies TLI493DW2BWA3XTMA1

Overview

TLI493DW2BWA3XTMA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor 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 just 7 nA in power-down mode. It is used in compact rotary position systems such as mobile camera lens focus/zoom actuators and end-of-shaft angle sensing.

For engineers reviewing the TLI493DW2BWA3XTMA1 datasheet, TLI493DW2BWA3XTMA1 pinout, TLI493DW2BWA3XTMA1 application, or TLI493DW2BWA3XTMA1 equivalent, key selection criteria include its ultra-low quiescent current, configurable wake-up thresholds per axis, X-Y angular mode, I²C clock-stretching support via /INT, and SG-WFWLB-5-2 wafer-level chip-scale package.

Technical Context

The device integrates three orthogonal Hall plates (X, Y, Z) sequentially multiplexed into a tracking ADC, enabling synchronized 12-bit magnetic field digitization. Its dual-oscillator architecture-comprising a fast oscillator for measurement and a low-power oscillator for standby-enables dynamic power mode switching without external timing components.

Wake-Up logic independently compares each axis against programmable upper/lower thresholds; an OR-combined /INT pulse signals field-change events to the host MCU. The I²C interface supports standard-mode (100 kHz) and fast-mode (400 kHz), with open-drain SDA/SCL and dedicated /INT output capable of clock stretching when tied to SCL.

Key Specifications

Pinout & Package

TLI493DW2BWA3XTMA1 uses the SG-WFWLB-5-2 wafer-level chip-scale package-a 5-terminal, 0.4 mm pitch, bottom-side solderable construction with index marking for orientation. No external passive components are required for basic operation.

FAQ

What is the default I²C address for TLI493DW2BWA3XTMA1?

The default I²C write address is 0x88H and read address is 0x89H, corresponding to the A3 variant marked "3DW3" on the top-side laser marking. This address is factory-programmed and non-configurable. Pulling the SDA line low during power-up does not alter the address-only hardware variants (A0–A3) provide different fixed addresses.

Can the /INT pin be used without connecting it to SCL?

Yes-the /INT pin functions as a standalone open-drain interrupt output and may be connected directly to any GPIO-capable MCU pin. In this configuration, the sensor asserts /INT after each completed measurement cycle or Wake-Up event, independent of I²C activity. Clock stretching is disabled, but bus reliability improves in electrically noisy environments.

How is temperature compensation implemented in this sensor?

Temperature compensation is performed internally using the integrated 10-bit on-die sensor. The sensor automatically applies gain and offset corrections to X/Y/Z Hall readings based on real-time die temperature, with coefficients stored in OTP memory. No host MCU intervention is required-compensated magnetic data is delivered directly via I²C registers.

Does TLI493DW2BWA3XTMA1 support magnetic field calibration in-system?

No-this device does not support runtime offset or sensitivity calibration. It ships with factory-trimmed parameters stored in one-time-programmable (OTP) memory. System-level calibration (e.g., for magnet nonlinearity or PCB crosstalk) must be performed in the host MCU firmware using raw or compensated data outputs.
