Infineon Technologies TLI493DW2BWA0XTMA1

Overview

TLI493DW2BWA0XTMA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor with I²C interface and hardware Wake-Up interrupt (/INT). It measures X/Y/Z magnetic flux density up to ±160 mT, delivers 12-bit resolution per axis plus 10-bit temperature sensing, operates from 2.8 V to 3.5 V, and consumes just 7 nA in power-down mode. It enables compact angular position sensing in battery-powered knobs and camera lens actuators.

For engineers reviewing the TLI493DW2BWA0XTMA1 datasheet, TLI493DW2BWA0XTMA1 pinout, TLI493DW2BWA0XTMA1 application, or TLI493DW2BWA0XTMA1 equivalent, key selection criteria include its ultra-low standby current, configurable wake-up thresholds per axis, integrated temperature sensor, and SG-WFWLB-5-2 wafer-level chip-scale package for space-constrained PCB layouts.

Technical Context

The device integrates three orthogonal Hall plates (X, Y, Z), a successive-approximation ADC, dual oscillators (LP-OSC and F-OSC), and an I²C slave interface with register-based configuration. Power mode control manages transitions between sleep, wake-up, and measurement cycles without external timing components.

Wake-Up functionality compares each axis's magnetic field against independently programmable upper/lower thresholds; an /INT pulse is asserted when any axis breaches its envelope. The /INT pin supports open-drain clock stretching when tied to SCL, enabling synchronous measurement notification without polling.

Key Specifications

Pinout & Package

TLI493DW2BWA0XTMA1 uses the SG-WFWLB-5-2 wafer-level chip-scale package (WLCSP) with 5 terminals arranged in a 3×2 grid (pins A1, A3, B2, C1, C3). No solder mask defined; requires controlled-depth reflow and underfill for reliability in thermal cycling.

FAQ

What is the default I²C address for TLI493DW2BWA0XTMA1?

The default 7-bit I²C write address is 0x6A (1101010b), corresponding to read address 0x6B. This is fixed for the A0 variant marked "3DW0" and cannot be changed via pins or registers-address selection requires hardware variants (A1–A3) with different bond options.

Can the /INT pin be used independently from the I²C bus?

Yes-the /INT pin functions as a standalone open-drain interrupt output. It can be wired directly to a GPIO interrupt pin on the host MCU, decoupling wake-up signaling from I²C bus activity and avoiding clock stretching conflicts during high-traffic communication periods.

How does temperature compensation work in this sensor?

The integrated 10-bit temperature sensor continuously monitors die temperature and feeds data to internal calibration registers. During X/Y/Z measurements, offset and sensitivity coefficients are dynamically adjusted using factory-trimmed lookup tables, maintaining ±0.5° angular accuracy from −40°C to +125°C without host-side correction.

Is the SG-WFWLB-5-2 package compatible with standard reflow profiles?

Yes-it is qualified for IPC/JEDEC J-STD-020 Level 1 (unlimited floor life) and supports peak reflow temperatures up to 260°C. However, due to its 0.4 mm ball pitch and lack of solder mask defined pads, stencil design must use 0.12 mm thickness and 1:1 aperture ratio to prevent bridging and voiding.
