Product details
Overview
TLE493DW2B6A1HTSA1 from Infineon is a low-power 3D Hall sensor IC for automotive position sensing, featuring ±160 mT magnetic range, 12-bit XYZ field resolution, integrated 10-bit temperature sensor, I²C interface with configurable slave address 0x44/0x45, and wake-up interrupt (/INT) triggered by X/Y/Z field threshold crossing. It operates from 2.8 V to 3.5 V over −40°C to +125°C and supports diagnostic self-checks of analog/digital/Hall probe blocks.
For engineers reviewing the TLE493DW2B6A1HTSA1 datasheet, TLE493DW2B6A1HTSA1 pinout, TLE493DW2B6A1HTSA1 application, or TLE493DW2B6A1HTSA1 equivalent, key selection criteria include its 7 nA power-down current, X-Y angular measurement mode, programmable flux resolution down to 65 µT (typ), configurable update rates, and functional safety support via on-chip diagnostics.
Technical Context
The TLE493DW2B6A1HTSA1 integrates three orthogonal Hall plates (X, Y, Z) sequentially multiplexed to a successive-approximation ADC, enabling simultaneous 3D field vector capture. Its power mode control unit manages dual oscillators (fast and low-power), undervoltage detection, and accurate restart behavior - critical for automotive cold-crank robustness.
Wake-up functionality operates independently per axis using user-configurable upper/lower magnetic thresholds; an /INT pulse is asserted when any axis breaches its envelope. The I²C interface supports standard-mode (100 kHz) and fast-mode (400 kHz) timing, with open-drain SDA/SCL and dedicated /INT output for microcontroller event synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Magnetic Range | ±160 mT per axis - enables robust position detection in high-field environments like gear stick or pedal assemblies. |
| Flux Resolution | 65 µT (typ) - supports fine angular discrimination in X-Y mode for multi-function knob applications. |
| Power-Down Current | 7 nA (typ) - allows ultra-low standby consumption in battery-sensitive systems such as EV door modules. |
| Data Resolution | 12-bit per axis + 10-bit temperature - delivers precise field vector and thermal compensation without external ADC. |
| Supply Voltage | 2.8 V to 3.5 V - matches automotive 3.3 V rail with margin for transients and droop. |
| Operating Temperature | −40°C to +125°C (Tj) - qualified for under-hood and steering column mounting locations. |
| I²C Address | 0x44 (write), 0x45 (read) - avoids bus conflict in multi-sensor clusters using A1 variant. |
Pinout & Package
Package: PG-TSOP6-6-8 - thermally enhanced 6-pin thin shrink small outline package with exposed pad for improved heat dissipation in automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL /INT | I²C clock input / Wake-up interrupt output | Open-drain interrupt signal asserts on magnetic threshold breach; shared pin requires pull-up and careful timing coordination with I²C activity. |
| 2: GND | Ground reference | Primary ground connection for analog/digital domains; must be low-impedance to minimize noise coupling into Hall sensing. |
| 3: GND | Ground reference | Dedicated ground pin improves supply rejection and reduces crosstalk between internal biasing and measurement paths. |
| 4: VDD | Supply voltage input | Accepts 2.8–3.5 V; internal UVLO prevents operation below safe biasing threshold, ensuring reliable startup after cold crank. |
| 5: GND | Ground reference | Third ground pin enhances thermal and electrical stability for high-accuracy 3D field measurement across temperature extremes. |
| 6: SDA | I²C bidirectional data line | Open-drain interface supports multi-drop configurations; requires external pull-up resistor sized for bus capacitance & rise-time compliance. |
Key Features
| Feature | Design Value |
|---|---|
| X-Y angular measurement mode | Enables contactless rotary position sensing without mechanical stops or potentiometers - reduces wear and improves long-term reliability in steering wheel controls. |
| Integrated diagnostics | Self-test capability for digital logic, analog front-end, and Hall probe integrity - satisfies ASIL-B functional safety requirements without external test circuitry. |
| Configurable wake-up thresholds | User-defined upper/lower magnetic limits per axis allow adaptive sensitivity tuning - eliminates false triggers from stray fields while maintaining responsiveness to target motion. |
| Variable update frequency | Measurement rate adjustable from 1 Hz to 100 Hz via I²C register - balances latency and power in applications like pedal position where dynamics vary widely. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV493DW2B6A1HTSA1 | Same pinout and function but manufactured by Melexis; identical 12-bit resolution, ±160 mT range, and I²C interface; differs in ESD rating (±2 kV HBM vs. Infineon's ±2 kV) and default I²C address (0x5E). | Valid drop-in replacement in non-safety-critical consumer or industrial designs; not AEC-Q200 qualified for automotive use. | Select when cost or lead time favors Melexis sourcing, provided functional safety certification is not required. |
| MLX90393ELW-ABA-000-SP | Tri-axis Hall sensor with SPI interface, 16-bit resolution, ±50 mT range, and higher temperature grade (−40°C to +150°C); lacks integrated wake-up interrupt and requires external GPIO for event signaling. | Better suited for high-temperature engine bay applications requiring extended range precision, but adds MCU firmware overhead for SPI polling and interrupt emulation. | Choose for extreme thermal environments where ±50 mT range suffices and SPI infrastructure already exists. |
Compared with TLV493DW2B6A1HTSA1 and MLX90393ELW-ABA-000-SP, the TLE493DW2B6A1HTSA1 uniquely combines AEC-Q100 qualification, integrated /INT wake-up, and automotive-grade diagnostics - making it optimal for safety-critical position sensing where deterministic low-power operation and functional safety evidence are mandatory.

FAQ
What is the default I²C slave address for TLE493DW2B6A1HTSA1?
The TLE493DW2B6A1HTSA1 uses a fixed I²C write address of 0x44 and read address of 0x45, corresponding to the "A1" variant in Infineon's ordering matrix. This address is hardwired and cannot be changed via configuration registers or external pins.
How does the wake-up interrupt (/INT) behave during I²C communication?
The /INT signal is inhibited during active I²C transactions to prevent collision with bus arbitration. Once the I²C transfer completes, wake-up monitoring resumes immediately. This behavior is hardware-enforced and does not require software masking or clearing of interrupt flags.
Can the TLE493DW2B6A1HTSA1 operate reliably at 2.75 V supply?
No - the absolute minimum supply voltage is 2.8 V per specification. Operation below this level risks incomplete internal biasing, unreliable ADC conversion, and failure of the undervoltage lockout (UVLO) circuit to release properly, leading to undefined startup behavior or measurement errors.
Is the temperature sensor calibrated across the full operating range?
Yes - the integrated 10-bit temperature sensor is factory-calibrated from −40°C to +125°C, with typical accuracy of ±2.5°C over that range. Calibration coefficients are stored in device ROM and applied automatically during measurement, requiring no host MCU compensation.
