Product details

Overview

TLE493DW2B6A3HTSA1 from Infineon Technologies is a low-power 3D Hall-effect magnetic sensor IC with I²C interface, wake-up function, and integrated diagnostics for automotive position sensing. It measures magnetic flux density in X/Y/Z axes up to ±160 mT, provides 12-bit resolution per axis plus 10-bit temperature sensing, operates from 2.8 V to 3.5 V, and consumes 7 nA (typ.) in power-down mode. Used in gear stick position detection and multi-function steering wheel controls.

For engineers reviewing the TLE493DW2B6A3HTSA1 datasheet, TLE493DW2B6A3HTSA1 pinout, TLE493DW2B6A3HTSA1 application, or TLE493DW2B6A3HTSA1 equivalent, key selection factors include its ±160 mT 3D field range, programmable 65 µT flux resolution, wake-up interrupt capability per axis, diagnostic coverage of analog/digital/Hall probe blocks, and PG-TSOP6-6-8 package compatibility with space-constrained automotive modules.

Technical Context

The TLE493DW2B6A3HTSA1 integrates three orthogonal Hall plates (X/Y/Z), a successive-approximation ADC, temperature sensor, and I²C slave interface with configurable address (88H/89H). Its power mode control includes dual oscillators (fast and low-power) and undervoltage detection, enabling accurate restart and stable operation across -40°C to +125°C junction temperature.

Wake-up functionality uses independent upper/lower thresholds per axis to generate an open-drain /INT signal when field changes exceed envelope limits - supporting ultra-low-power system sleep states. All measurements and diagnostics are digitally accessible via I²C register reads, with no external components required for basic operation.

Key Specifications

Parameter	Value and Actual Design Meaning
3D Magnetic Range	±160 mT per axis - enables robust position sensing despite mechanical tolerances and stray fields in automotive cabins.
Flux Resolution	65 µT (typ.) - supports fine angular discrimination in knob or pedal position applications.
Data Resolution	12-bit per axis + 10-bit temperature - delivers precise digital output without external ADC or signal conditioning.
Supply Voltage	2.8 V to 3.5 V - matches automotive 3.3 V rail with margin for transients and dropouts.
Power-Down Current	7 nA (typ.) - extends battery life in always-on vehicle subsystems like gear selectors.
I²C Address	88H (write) / 89H (read) - allows coexistence with other I²C devices on same bus without conflict.
Operating Temp	-40°C to +125°C (Tj) - qualified for under-hood and cabin-mounted automotive ECUs.

Pinout & Package

Package: PG-TSOP6-6-8 - thermally enhanced, surface-mount 6-pin thin small-outline package with exposed pad for improved heat dissipation in compact automotive modules.

Pin/Terminal	Circuit Role	Design Meaning
1: SCL /INT	I²C clock input / Wake-up interrupt output	Open-drain interrupt signal indicates completed measurement cycle; shared pin reduces footprint but requires careful timing coordination.
2: GND	Ground reference	Dedicated ground pin improves noise immunity for analog Hall sensing paths.
3: GND	Ground reference	Second ground pin lowers impedance path for return currents, critical for precision magnetic measurement stability.
4: VDD	Supply voltage input	Single 2.8–3.5 V supply powers all internal blocks including Hall biasing, ADC, and I²C interface.
5: GND	Ground reference	Third ground pin minimizes ground bounce during fast ADC conversions and I²C transitions.
6: SDA	I²C bidirectional data line	Open-drain configuration ensures bus arbitration and compatibility with standard I²C masters in microcontroller-based systems.

Key Features

Feature	Design Value
X-Y angular measurement mode	Enables contactless rotary position detection using only two axes - eliminates need for external magnets or complex mechanical linkages.
Integrated diagnostics	Self-tests digital logic, analog front-end, and Hall probes - satisfies ASIL-B functional safety requirements without external monitoring circuitry.
Configurable update frequency	Allows dynamic trade-off between latency and power consumption - e.g., 1 Hz for parking sensors vs. 100 Hz for real-time pedal feedback.
Wake-up threshold per axis	Independent high/low limits on X, Y, Z channels enable selective sensitivity to directional field changes - reduces false triggers in noisy environments.
Temperature sensor	On-die 10-bit thermal measurement compensates Hall offset drift - maintains accuracy over full automotive temperature range without calibration tables.

Applications

Gear Stick Position Sensing

Multi-Function Steering Wheel Controls

Use Scenario: Detecting discrete gear positions (P/R/N/D) and intermediate detents in automatic transmission shifters.

IC Role / Device Role / Timing Role: Primary 3D magnetic position sensor providing digital angle and magnitude data via I²C to transmission control unit.

Use Value: Replaces potentiometers and reed switches with higher reliability, no mechanical wear, and immunity to dust/moisture ingress.

Use Scenario: Reading rotational position and push-button actuation of steering wheel-mounted controls for cruise, audio, and phone functions.

IC Role / Device Role / Timing Role: Dual-role sensor delivering angular displacement (X-Y mode) and proximity-triggered wake-up (/INT) to body domain controller.

Use Value: Enables zero-power standby until driver interaction, reducing ECU quiescent current by >99% versus always-active polling.

Pedal/Valve Position Sensing

Top Column Module Actuation

Use Scenario: Measuring accelerator or brake pedal travel in drive-by-wire systems with fail-safe redundancy.

IC Role / Device Role / Timing Role: Safety-critical position transducer feeding primary and secondary signal paths to engine/brake ECUs.

Use Value: Integrated diagnostics and 125°C operation meet ISO 26262 ASIL-B requirements without external watchdog or validation hardware.

Use Scenario: Detecting lever movement and button presses in column-mounted stalks for turn signals, wipers, and headlights.

IC Role / Device Role / Timing Role: Low-latency magnetic sensor interfacing directly to LIN or CAN gateway MCU via I²C.

Use Value: Compact TSOP6 footprint fits tight column cavities; wake-up interrupt eliminates continuous polling overhead in low-power gateways.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3D Hall position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV493DW2B6A3HTSA1	Same pinout and I²C interface, but lower max field range (±130 mT) and higher power-down current (15 nA).	Limited suitability for high-stray-field environments like near electric motors or solenoids.	Select when cost optimization is prioritized and magnetic environment is well-controlled.
MLX90393ELW-ABA-000-TU	Tri-axis Hall with SPI interface, 16-bit resolution, wider supply (1.7–3.6 V), but larger SOIC-16 package.	Requires PCB redesign due to different footprint and communication protocol; better for high-precision industrial use.	Choose for applications needing higher resolution or SPI integration, accepting larger size and layout change.

Compared with TLV493DW2B6A3HTSA1 and MLX90393ELW-ABA-000-TU, the TLE493DW2B6A3HTSA1 offers superior magnetic range and lowest quiescent current in a compact TSOP6 package - making it optimal for space- and power-constrained automotive interior sensing where field strength and reliability are critical.

FAQ

What is the default I²C address for TLE493DW2B6A3HTSA1?

The default write address is 0x88 (88H) and read address is 0x89 (89H), corresponding to the A3 variant marked on the device. This address is fixed and not software-configurable - multiple units require hardware address selection via external pins or separate I²C buses.

How does the wake-up function operate independently per axis?

Each axis (X/Y/Z) has dedicated upper and lower magnetic threshold registers. When any measured field component crosses its assigned envelope, the /INT pin asserts. The interrupt is the logical OR of all three channel comparisons, allowing selective sensitivity to motion along specific directions without cross-axis interference.

Can the TLE493DW2B6A3HTSA1 operate without an external pull-up resistor on SDA/SCL?

No - external 1.2 kΩ pull-up resistors on both SDA and SCL are mandatory per the datasheet application circuit. The open-drain I²C interface cannot drive high without them, and omission causes communication failure or intermittent lockup during wake-up sequences.

Is the temperature sensor calibrated and usable for system thermal monitoring?

Yes - the on-die 10-bit temperature sensor is factory-calibrated and provides absolute junction temperature readings with ±2.5°C accuracy from -40°C to +125°C. It is automatically sampled after each 3-axis magnetic measurement and accessible via dedicated I²C register, enabling real-time thermal compensation or system-level thermal management.
