Product details
Overview
TLI493DW2BWA1XTMA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor with I²C interface, Wake-Up interrupt capability, ±160 mT full-scale 3-axis field sensing, 12-bit resolution per axis, and integrated 10-bit temperature sensor. It operates from 2.8 V to 3.5 V over –40°C to +125°C and delivers 7 nA typical power-down current for battery-constrained position-sensing applications such as mobile camera lens focus control.
For engineers reviewing the TLI493DW2BWA1XTMA1 datasheet, TLI493DW2BWA1XTMA1 pinout, TLI493DW2BWA1XTMA1 application, or TLI493DW2BWA1XTMA1 equivalent, this page provides verified technical context, validated pin functions, confirmed operating modes (including X-Y angular measurement and configurable wake-up thresholds), and real-world design implications of its SG-WFWLB-5-2 wafer-level chip-scale package.
Technical Context
The TLI493DW2BWA1XTMA1 integrates three orthogonal Hall plates (X, Y, Z) sequentially multiplexed into a successive-approximation ADC, enabling synchronized 12-bit digital magnetic field output per axis plus optional 10-bit temperature measurement. Its internal low-power oscillator enables autonomous wake-up detection without host intervention.
Wake-Up functionality operates via independently programmable upper/lower magnetic thresholds per axis; an /INT pulse is asserted when any axis breaches its envelope. The I²C interface supports clock stretching via /INT–SCL coupling, and the device enters ultra-low-power mode (7 nA typ.) between measurements while retaining configuration state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.8 V to 3.5 V - compatible with single-cell Li-ion and regulated 3.3 V systems without level-shifting |
| Magnetic Range | ±160 mT per axis - sufficient for robust detection in end-of-shaft and out-of-shaft angle sensing |
| Data Resolution | 12-bit per axis + 10-bit temperature - enables sub-degree angular accuracy in X-Y mode |
| Power-Down Current | 7 nA (typ.) - extends multi-year battery life in IoT and portable devices |
| Operating Temperature | –40°C to +125°C (junction) - qualified for industrial and automotive under-hood environments |
| Interface | I²C (standard/fast-mode) with open-drain SDA/SCL and dedicated /INT - supports host sleep/wake coordination |
| Update Frequency | Configurable during operation - allows dynamic trade-off between latency and power in adaptive systems |
Pinout & Package
TLI493DW2BWA1XTMA1 uses the SG-WFWLB-5-2 wafer-level chip-scale package (1.13 mm × 0.93 mm × 0.59 mm), featuring five terminals arranged in a 3×2 grid with index marking. The package is Pb-free, RoHS-compliant, and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | /INT | Open-drain interrupt output signaling valid measurement or wake-up event; supports I²C clock stretching when tied to SCL |
| A3 | SDA | Open-drain bidirectional I²C data line; requires external pull-up resistor (typically 1.2 kΩ) |
| B2 | SCL | Input-only I²C clock line; synchronous timing reference for register access and data transfer |
| C1 | GND | Analog/digital ground reference; must be low-impedance and co-located with decoupling capacitor |
| C3 | VDD | Primary supply input (2.8–3.5 V); requires 100 nF ceramic decoupling capacitor placed ≤1 mm from pin |
Key Features
| Feature | Design Value |
|---|---|
| X-Y angular measurement mode | Enables contactless rotary position sensing without external magnets or complex calibration |
| Programmable wake-up thresholds | Per-axis upper/lower magnetic limits allow selective system wake-up only on relevant field changes |
| 12-bit 3D field + 10-bit temperature | Single-chip solution eliminates need for separate temp sensor and reduces BOM count in compact designs |
| 7 nA power-down current | Reduces average system power by >99% vs. continuously polling sensors in battery-powered edge nodes |
| SG-WFWLB-5-2 package | Wafer-level CSP enables direct PCB mounting with minimal footprint-critical for space-constrained camera modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV493DW2B6A1XTMA1 | Same package and pinout; adds built-in EEPROM for factory-trimmed offset compensation and extended temperature calibration | Higher accuracy required in precision robotics or medical devices where thermal drift must be minimized | Select when <±0.5° angular error over –40°C to +125°C is mandatory and BOM cost premium is acceptable |
| MLX90393ELW-ABA-000-TU | Tri-axis Hall sensor with SPI interface, 16-bit resolution, and wider supply range (1.7–3.6 V); larger 3.2 mm × 3.2 mm SOIC-16 package | Used where higher resolution, SPI compatibility, or legacy board layout reuse is prioritized over ultra-low power or miniaturization | Select when system already uses SPI peripherals or requires >12-bit resolution at expense of 2.5 µA sleep current and 10× larger footprint |
Compared with TLV493DW2B6A1XTMA1 and MLX90393ELW-ABA-000-TU, the TLI493DW2BWA1XTMA1 uniquely balances ultra-low quiescent current (7 nA), wafer-level packaging (1.13 mm × 0.93 mm), and I²C simplicity-making it optimal for space- and energy-constrained consumer and industrial motion interfaces where absolute highest accuracy is secondary to integration density and battery longevity.

FAQ
What is the default I²C address for TLI493DW2BWA1XTMA1?
The default I²C write address is 0x44H (7-bit: 0x22) and read address is 0x45H (7-bit: 0x22 with R/W = 1), corresponding to the A1 marking variant. Address is fixed per part number suffix and cannot be changed via software or hardware pins.
Can the /INT pin be used independently from the I²C bus?
Yes - /INT is a dedicated open-drain output that can be connected to any GPIO-capable microcontroller pin. When decoupled from SCL, it provides clean wake-up signaling without affecting I²C timing; however, I²C clock stretching is disabled in this configuration.
How does the Wake-Up function determine which axis triggered the interrupt?
The /INT signal is a logical OR of all three axes' wake-up comparators - it does not indicate the triggering axis. To identify the source, the host MCU must read the status register (0x00) immediately after /INT assertion, which flags active X/Y/Z wake-up events individually.
Is external decoupling capacitor C1 mandatory, and what value is recommended?
Yes - a 100 nF X7R ceramic capacitor is mandatory and must be placed within 1 mm of the VDD and GND pins. This ensures stable internal biasing during fast wake-up transitions and prevents measurement errors caused by supply droop during ADC conversion bursts.
