Product details
Overview
TLI493DA2B6HTSA1 from Infineon Technologies is a low-power 3D Hall-effect sensor IC with I²C interface, measuring magnetic flux density in X/Y/Z axes up to ±160 mT, featuring 12-bit directional resolution, integrated 10-bit temperature sensing, and programmable flux resolution down to 65 µT (typ.), deployed in multi-function knobs and robotic position sensing.
For engineers reviewing the TLI493DA2B6HTSA1 datasheet, TLI493DA2B6HTSA1 pinout, TLI493DA2B6HTSA1 application, or TLI493DA2B6HTSA1 equivalent, key selection criteria include its 7 nA (typ.) power-down current, configurable update rates, TSOP6-6-8 package footprint, and interrupt-driven measurement signaling via open-drain /INT pin.
Technical Context
The device integrates three orthogonal Hall plates (X, Y, Z), sequentially multiplexed to a successive-approximation ADC, with on-chip temperature sensing enabled by default. Its power mode control uses dual oscillators - a fast oscillator for active measurement and a low-power oscillator for standby - enabling dynamic reconfiguration over I²C without reset.
As an I²C slave, it supports standard-mode (100 kHz) and fast-mode (400 kHz) timing, with SDA and SCL pins implemented as open-drain I/O. The /INT pin asserts after each completed measurement cycle, allowing microcontroller-triggered readout without polling, reducing system-level power consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.8 V to 3.5 V - compatible with 3.3 V logic systems; undervoltage detection halts operation below restart threshold. |
| Magnetic Range (X/Y/Z) | ±160 mT - enables robust angular and position sensing in presence of mechanical tolerances or stray fields. |
| Flux Resolution | 65 µT (typ.) - supports high-precision angle calculation in joystick and gimbal applications. |
| Power-Down Current | 7 nA (typ.) - allows battery-powered devices (e.g., smart meters) to maintain years-long operational life in sleep state. |
| Data Resolution | 12-bit per axis + 10-bit temperature - delivers >4,000 discrete steps per dimension for fine-grained motion tracking. |
| Operating Temperature | −40°C to +105°C (junction) - qualified for industrial and white goods environments including washer/dryer motor control zones. |
| I²C Address | 0x6A (write), 0x6B (read) - fixed hardware address simplifies firmware initialization in multi-sensor systems. |
Pinout & Package
TLI493DA2B6HTSA1 is housed in a PG-TSOP6-6-8 surface-mount package (6-pin, 1.6 mm × 2.9 mm, 0.65 mm pitch), optimized for compact PCB layouts in space-constrained consumer and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL /INT | I²C clock input / interrupt output | Shared pin: input for I²C clock during configuration; open-drain output signals measurement completion to MCU. |
| 2: GND | Ground reference | Primary ground connection; decoupling capacitor must be placed adjacent to this pin for noise immunity. |
| 3: GND | Ground reference | Dedicated second ground path reduces thermal resistance and improves signal integrity in noisy environments. |
| 4: VDD | Supply voltage input | Single 3.3 V supply powers all internal blocks; internal UVLO prevents erratic behavior during brown-out conditions. |
| 5: GND | Ground reference | Third ground terminal enhances EMC performance and stabilizes Hall plate biasing under dynamic field conditions. |
| 6: SDA | I²C bidirectional data line | Open-drain I/O supports standard I²C bus topology; requires external pull-up resistor (1.2 kΩ typical). |
Key Features
| Feature | Design Value |
|---|---|
| X-Y angular measurement mode | Enables contactless rotation detection without external magnets or complex calibration-ideal for rotary encoders in appliances. |
| Configurable update frequency | Allows runtime trade-off between latency (up to 1 kHz) and power (down to 7 nA), supporting adaptive duty cycling in portable devices. |
| Interrupt-driven measurement signaling | Eliminates polling overhead and guarantees deterministic readout timing-critical for real-time robotics feedback loops. |
| Integrated temperature sensor | 10-bit thermal reading compensates Hall offset drift across −40°C to +105°C, improving long-term accuracy in uncontrolled environments. |
| Stray-field resilience | High ±160 mT range suppresses interference from nearby motors or solenoids, reducing need for magnetic shielding in white goods. |
Applications
| Multi-Function Knobs | Robotic Joint Position Sensing |
|---|---|
|
Use Scenario: Rotary user interface in smart home hubs and HVAC controllers requiring precise angular input without mechanical wear. IC Role / Device Role / Timing Role: 3D Hall sensor providing X-Y angular output via I²C; /INT triggers MCU readout only when knob movement completes. Use Value: Replaces potentiometers and optical encoders, eliminating contact degradation and enabling sealed, dust-proof front panels. |
Use Scenario: Non-contact joint angle monitoring in collaborative robots operating near motors and EMI sources. IC Role / Device Role / Timing Role: Z-axis field sensing detects magnet displacement along actuator shaft; I²C delivers synchronized X/Y/Z samples at 200 Hz. Use Value: Survives vibration and thermal cycling where optical sensors fail; ±160 mT range rejects interference from adjacent servo drivers. |
| Smart Meter Anti-Tampering | Washing Machine Drum Position |
|
Use Scenario: Detection of unauthorized meter cover removal or magnetic tampering attempts in utility-grade electricity meters. IC Role / Device Role / Timing Role: Always-on low-power monitor sampling Z-field every 5 s; /INT wakes MCU only upon field anomaly exceeding ±50 mT threshold. Use Value: 7 nA sleep current extends 10-year battery life; integrated temperature compensation avoids false alarms due to ambient drift. |
Use Scenario: Real-time drum tilt and spin-angle tracking during wash cycles to optimize water distribution and imbalance correction. IC Role / Device Role / Timing Role: Mounted on drum shaft; measures X/Y field vectors to compute absolute angular position at 100 Hz during high-speed spin. Use Value: Enables closed-loop control of drum motion without slip rings or wiring through rotating assembly-reducing maintenance and failure points. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV493D-A1B6 | Same TSOP6 package and I²C interface, but ±130 mT range and 100 µT min. resolution; lacks /INT pin. | No interrupt signaling - requires MCU polling, increasing average power in battery systems. | Select when cost sensitivity outweighs interrupt-driven efficiency and extended magnetic range is unnecessary. |
| MLX90393ELD-ABA-000-RE | Tri-axis Hall sensor with SPI/I²C, ±200 mT range, 16-bit resolution, but 1.5 µA sleep current and SOIC-16 package. | Larger footprint and higher quiescent current limit use in ultra-low-power or space-constrained designs. | Prefer when higher resolution and wider range justify larger size and increased BOM cost in industrial automation. |
Compared with TLV493D-A1B6 and MLX90393ELD-ABA-000-RE, TLI493DA2B6HTSA1 uniquely balances ultra-low 7 nA sleep current, interrupt capability, and compact TSOP6 packaging - making it optimal for battery-powered consumer interfaces and compact industrial actuators where power and board area are critical.

FAQ
What is the default I²C address of TLI493DA2B6HTSA1?
The device ships with a fixed hardware I²C address: 0x6A for write operations and 0x6B for read operations. No address pins or configuration registers exist to modify this value, ensuring deterministic bus initialization in multi-sensor systems without address conflict risk.
Can TLI493DA2B6HTSA1 operate without the /INT pin connected?
Yes - the /INT pin is optional. In its absence, the microcontroller must poll the status register via I²C to detect measurement completion. However, omitting /INT increases average system power and introduces latency uncertainty, especially in low-duty-cycle applications.
How does the temperature sensor improve measurement accuracy?
The integrated 10-bit temperature sensor monitors die temperature in real time, enabling firmware-based compensation of Hall plate offset and sensitivity drift across −40°C to +105°C. This eliminates need for external thermal sensors or factory calibration tables in end equipment.
Is TLI493DA2B6HTSA1 qualified for automotive use?
No - TLI493DA2B6HTSA1 is specified for industrial temperature range (−40°C to +105°C) and carries no AEC-Q100 qualification. For automotive applications, Infineon offers the pin-compatible TLI493D-A2BW variant, which meets AEC-Q100 Grade 1 requirements and includes enhanced ESD and EMC robustness.
