Infineon Technologies TLI493DW2BWA0XTSA1

Overview

TLI493DW2BWA0XTSA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor with I²C interface and Wake-Up interrupt functionality. It measures X/Y/Z magnetic flux density up to ±160 mT, provides 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 is used in mobile camera lens position sensing for autofocus and optical zoom control.

For engineers reviewing the TLI493DW2BWA0XTSA1 datasheet, TLI493DW2BWA0XTSA1 pinout, TLI493DW2BWA0XTSA1 application, or TLI493DW2BWA0XTSA1 equivalent, key selection criteria include its ultra-low standby current, configurable wake-up thresholds per axis, 3D angular measurement capability, and SG-WFWLB-5-2 wafer-level chip-scale package compatibility with space-constrained embedded systems.

Technical Context

The TLI493DW2BWA0XTSA1 integrates three orthogonal Hall plates (X, Y, Z) with sequential multiplexed ADC conversion and on-chip temperature sensing. Its digital output is delivered via I²C at user-configurable update rates, supporting both standard (100 kHz) and fast-mode (400 kHz) timing.

Wake-Up operation uses independent upper/lower magnetic field thresholds per axis; an /INT pulse is asserted when any axis exceeds its envelope. The /INT pin supports open-drain clock stretching when tied to SCL, enabling synchronized microcontroller wake-up without polling.

FAQ

What is the default I²C address for TLI493DW2BWA0XTSA1?

The TLI493DW2BWA0XTSA1 (A0 variant) has a fixed I²C write address of 0x6A and read address of 0x6B. This is determined by the internal marking "3DW0" and cannot be changed via software or hardware pins. No address selection resistors or configuration registers exist for this variant.

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 programmable upper and lower magnetic thresholds. An /INT pulse is generated if *any* axis crosses its envelope-this is a logical OR of all three channel events. Thresholds are set via I²C register writes and persist through power cycles when stored in non-volatile configuration memory.

Can the /INT pin be used simultaneously with SCL for clock stretching?

Yes-the /INT pin is open-drain and fully compatible with I²C clock stretching when physically connected to the SCL line. During measurement completion or wake-up, the sensor pulls SCL low to hold the bus until the host reads data. This eliminates polling and ensures deterministic timing without additional GPIO resources.

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

Yes-the SG-WFWLB-5-2 package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C). Its copper pillar interconnects and solder mask-defined pads ensure reliable attachment on fine-pitch PCBs without tombstoning or voiding concerns.
