Product details
Overview
TLV493DA1B6HTSA2 from Infineon Technologies is a low-power 3D magnetic sensor IC with integrated temperature sensing, I²C interface, and ±130 mT linear field measurement in X/Y/Z axes. It delivers 12-bit resolution per axis at 10 Hz typical operation with 10 µA supply current, and supports configurable power modes including 7 nA shutdown. Used in joystick position sensing, white goods control knobs, and anti-tampering electric meters.
For engineers reviewing the TLV493DA1B6HTSA2 datasheet, TLV493DA1B6HTSA2 pinout, TLV493DA1B6HTSA2 application, or TLV493DA1B6HTSA2 equivalent, key selection criteria include its TSOP-6 package footprint, dual I²C address configuration via ADDR pin, interrupt-driven wake-up capability, and guaranteed operation from –40°C to +125°C junction temperature.
Technical Context
The TLV493DA1B6HTSA2 integrates three spinning vertical Hall plates (X/Y/Z) sequentially multiplexed to a successive-approximation ADC, enabling simultaneous 3D field vector acquisition. Its power mode controller uses a low-power oscillator and fast oscillator to manage startup, reset detection, and dynamic mode switching without external timing components.
Each Hall channel provides linear Bx/By/Bz output with <±1% gain matching between X and Y axes-critical for high-accuracy angular calculation. The on-chip temperature sensor (±1.5°C accuracy) operates by default and reduces current draw by 25% when disabled, supporting plausibility checks and thermal compensation in embedded motion systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Operating Temperature | –40°C to +125°C (Tj) - qualified for industrial and automotive under-hood environments. |
| Power Consumption | 10 µA @ 10 Hz (typ.), 7 nA in power-down - enables multi-year battery life in wireless sensors. |
| Magnetic Range | ±130 mT per axis (X/Y/Z) - supports robust detection of neodymium magnets at >10 mm air gap. |
| Output Resolution | 12-bit digital (I²C) - delivers 0.04 mT LSB for precise angular and linear displacement tracking. |

Pinout & Package
TLV493DA1B6HTSA2 is housed in a PG-TSOP-6-6-5 surface-mount package (3.0 × 1.6 × 0.95 mm), optimized for reflow soldering and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL /INT | I²C clock input / interrupt output | Open-drain interrupt signals measurement completion; doubles as I²C clock line-no pull-up required on INT if unused. |
| 2: GND | Ground reference | Dedicated ground pin for analog signal integrity; must be connected to low-impedance system ground plane. |
| 3: GND | Ground reference | Second ground pin improves thermal dissipation and reduces noise coupling in high-sensitivity 3D sensing. |
| 4: VDD | Supply voltage input | Accepts 2.8–3.5 V; internal UVLO prevents erroneous readings during brown-out conditions. |
| 5: GND | Ground reference | Third ground pin enhances EMC performance and stabilizes Hall biasing under dynamic field transients. |
| 6: SDA /ADDR | I²C data I/O / address select | Configures I²C address (0x5A or 0x5B) at power-up based on ADDR pin voltage; open-drain for bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| 3-axis Hall sensing with sequential ADC | Enables true 3D vector measurement using shared precision ADC-reduces die area and cross-axis interference. |
| Configurable power modes | Four modes (power-down, low-power, normal, high-speed) selectable via I²C-supports adaptive energy management. |
| Integrated temperature sensor | ±1.5°C accuracy over full range; used for magnetic offset compensation and system-level plausibility validation. |
| Interrupt-driven wake-up | /INT pin asserts after each measurement cycle-eliminates polling and cuts host MCU active time by >90%. |
| Dual I²C address support | Two hardware-selectable addresses (0x5A/0x5B) allow up to two sensors on same bus without software address remapping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D magnetic sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90393EDC-ABA-000-TU | Higher 16-bit resolution, wider ±200 mT range, SPI/I²C dual interface, but 25 µA typical current. | Better suited for high-precision industrial encoders; less optimal for ultra-low-power battery nodes. | Select when resolution and range outweigh power budget constraints. |
| TLE493DW2B6A0HTSA1 | Same Infineon family, identical TSOP-6 package and pinout, but adds wake-up-on-field-change and extended diagnostics. | Preferred for automotive ASIL-B designs requiring fault reporting and event-triggered sampling. | Choose for functional safety-critical systems needing built-in self-test and fail-safe signaling. |
Compared with MLX90393 and TLE493DW2B6A0, the TLV493DA1B6HTSA2 offers the lowest active current (10 µA) and simplest I²C implementation-ideal for cost-sensitive, long-life consumer and industrial motion interfaces where 12-bit resolution suffices.

FAQ
What is the default I²C address after power-up?
The TLV493DA1B6HTSA2 samples the voltage on the SDA/ADDR pin at power-on reset: logic low (≤0.3×VDD) selects 0x5A; logic high (≥0.7×VDD) selects 0x5B. No external pull-up or pull-down is required-the pin is internally biased during startup, and the address remains fixed until next power cycle.
Does the device require external calibration for angular measurement?
No factory or runtime calibration is required for basic angular position. The <±1% X/Y gain matching and inherent orthogonality of the on-die Hall plates enable direct arctangent calculation. Optional temperature compensation can be applied using the integrated sensor's ±1.5°C accurate readings.
How does the /INT pin function in different power modes?
The /INT pin asserts low after every completed measurement cycle-regardless of power mode. In power-down mode, it only triggers upon wake-up and first conversion. In continuous modes, it pulses once per configured update rate (e.g., every 100 ms at 10 Hz), allowing deterministic host synchronization without polling.
Can the temperature sensor be disabled to reduce power further?
Yes. Writing '0' to bit 7 of register 0x01 disables the temperature measurement stage, reducing total current consumption by ~25%. This also shortens the conversion time per cycle by skipping the temperature ADC step, increasing maximum achievable update rate.
