Product details
Overview
TLI493DW2BWA2XTMA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor with I²C interface and hardware Wake-Up interrupt capability. It measures magnetic flux density in X, Y, and Z axes 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 is used in compact rotary position sensing for mobile camera lens focus/zoom actuation.
For engineers reviewing the TLI493DW2BWA2XTMA1 datasheet, TLI493DW2BWA2XTMA1 pinout, TLI493DW2BWA2XTMA1 application, or TLI493DW2BWA2XTMA1 equivalent, key selection criteria include its ultra-low standby current, configurable wake-up thresholds per axis, X-Y angular measurement mode, I²C clock-stretching support via /INT pin, and SG-WFWLB-5-2 wafer-level chip-scale package compatibility.
Technical Context
The TLI493DW2BWA2XTMA1 integrates three orthogonal Hall plates (X, Y, Z) sequentially multiplexed to a tracking ADC, with on-chip temperature sensing enabled by default. Its power mode control uses dual oscillators - a low-power LP-OSC for sleep timing and a fast F-OSC for measurement cycles - enabling dynamic switching between ultra-low-power wake-up monitoring and full-resolution acquisition.
Wake-Up functionality operates independently per axis using programmable upper/lower magnetic thresholds; an /INT pulse is asserted when any axis breaches its envelope. The /INT pin supports open-drain output and can be wired to SCL for I²C clock stretching, eliminating need for a dedicated MCU interrupt pin while maintaining synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 3D Sensing Range | ±160 mT per axis - enables robust detection of strong magnets in tight mechanical gaps without saturation. |

Pinout & Package
TLI493DW2BWA2XTMA1 is housed in the SG-WFWLB-5-2 wafer-level chip-scale package - a 5-terminal, bottom-side solderable construction with no external leads, optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | /INT | Open-drain interrupt output signaling valid measurement completion or wake-up event; supports I²C clock stretching when tied to SCL. |
| A3 | SDA | Open-drain bidirectional I²C data line; requires external pull-up; shares bus arbitration with other I²C slaves. |
| B2 | SCL | Input-only I²C clock line; synchronizes all register reads/writes and initiates measurement cycles upon master command. |
| C1 | GND | Primary ground reference for analog and digital circuitry; must be low-impedance and thermally coupled to sensor die. |
| C3 | VDD | Single 2.8–3.5 V supply input powering internal biasing, oscillators, ADC, and I²C interface; bypass capacitor required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D magnetic sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV493DW2B6A1 | Same SG-WFWLB-5-2 package and I²C interface, but fixed I²C address (6AH/6BH only); lacks X-Y angular mode; 14-bit resolution per axis. | Targeted at high-accuracy linear position sensing rather than angular applications requiring on-sensor angle computation. | Select when absolute field magnitude precision > angular computation convenience, and system uses only one sensor per I²C bus. |
| MMC5603NJ | 3D Hall sensor with SPI/I²C dual interface; 20-bit resolution; 1.6 µA active current; no integrated wake-up comparator; larger DFN-8 package (2.0 × 2.0 mm). | Better suited for data loggers or lab equipment needing highest resolution, not ultra-low-power embedded wake-up systems. | Choose when measurement bandwidth > 1 kHz or when SPI interface simplifies host integration, accepting larger footprint and higher active power. |
Compared with TLV493DW2B6A1 and MMC5603NJ, the TLI493DW2BWA2XTMA1 uniquely combines ultra-low 7 nA standby current, on-chip X-Y angular calculation, and flexible I²C addressing - making it optimal for battery-powered consumer devices requiring compact, intelligent magnetic position awareness.

FAQ
What is the default I²C address for TLI493DW2BWA2XTMA1?
The marking "A2" on the device corresponds to I²C write address 0xF0 and read address 0xF1 (hexadecimal). This is confirmed in the ordering information table of the official Infineon datasheet V1.00, where A2 devices are assigned F0H/F1H addresses and shipped in 15k-reel packaging (SP005409968).
Can the /INT pin be used simultaneously as both interrupt output and I²C clock line?
Yes - the /INT pin supports open-drain I²C clock stretching when physically connected to the SCL line. This configuration is explicitly validated in Figure 5 of the datasheet and allows the sensor to hold SCL low until measurement completion, eliminating need for polling or separate interrupt routing.
Does TLI493DW2BWA2XTMA1 require external passive components for basic operation?
Yes - a 100 nF ceramic decoupling capacitor (C1) is mandatory between VDD and GND, placed as close as possible to the package. Pull-up resistors (typically 1.2 kΩ) on SDA and SCL are also required per I²C specification; values must be adjusted based on bus capacitance to meet rise/fall time requirements.
How is temperature compensation implemented in this sensor?
Temperature compensation is performed internally using the integrated 10-bit on-die temperature sensor. The sensor automatically applies calibrated gain/offset corrections to X, Y, and Z Hall channel outputs during each measurement cycle - no host MCU intervention or external calibration is needed for standard operation.
