Product details

Overview

TLE493DA2B6HTSA1 from Infineon Technologies is a low-power 3D Hall-effect sensor IC for automotive and industrial position sensing, delivering ±160 mT magnetic field measurement across X/Y/Z axes with 12-bit resolution per axis, integrated 10-bit temperature sensing, and I²C interface (default address 0x6A/0x6B) in PG-TSOP6-6-8 package. It operates from 2.8 V to 3.5 V over -40°C to +125°C and supports programmable flux resolution down to 65 µT (typ.) and power-down mode consuming 7 nA (typ.).

For engineers reviewing the TLE493DA2B6HTSA1 datasheet, TLE493DA2B6HTSA1 pinout, TLE493DA2B6HTSA1 application, or TLE493DA2B6HTSA1 equivalent, key selection criteria include 3D angular measurement capability, ultra-low standby current, I²C-configurable update rates, and automotive-grade thermal/EMC robustness in compact TSOP6 packaging.

Technical Context

The TLE493DA2B6HTSA1 integrates three orthogonal Hall plates (X, Y, Z), a successive-approximation ADC, low-power oscillator, and I²C slave interface. Its sensing unit sequentially measures all three axes plus temperature by default, with configurable measurement cycles and restart logic triggered by supply voltage thresholds.

Power mode control manages biasing, undervoltage detection, fast/low-power oscillators, and state transitions between sleep, wake-up, and measurement phases. The interrupt output (/INT) signals completion of valid measurements, enabling event-driven microcontroller readout without polling.

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 knob or steering wheel control elements.
Data Resolution	12-bit per axis + 10-bit temperature - provides sufficient granularity for closed-loop feedback and thermal compensation.
Supply Voltage	2.8 V to 3.5 V - compatible with automotive 3.3 V domains and battery-backed systems.
Standby Current	7 nA (typ.) - extends battery life in always-on vehicle subsystems such as column modules.
Operating Temp	-40°C to +125°C (Tj) - meets AEC-Q100 Grade 0 requirements for under-hood and cabin applications.
I²C Address	0x6A (write), 0x6B (read) - fixed dual-address configuration simplifies multi-sensor bus topology design.

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
1: SCL /INT	I²C clock input / open-drain interrupt output	Shared pin reduces footprint; /INT asserts low after valid measurement, eliminating polling overhead.
2: GND	Ground reference	Dedicated ground pin improves noise immunity for analog Hall sensing paths.
3: GND	Ground reference	Second ground pin enhances return path integrity and reduces ground bounce in high-speed I²C operation.
4: VDD	Power supply input	Single-supply operation at 2.8–3.5 V; internal UVLO ensures reliable startup above 2.5 V.
5: GND	Ground reference	Third ground connection stabilizes substrate potential and minimizes crosstalk between Hall elements.
6: SDA	I²C bidirectional data line (open-drain)	Supports standard/fast-mode I²C up to 400 kHz; pull-up required externally per bus specification.

Key Features

Feature	Design Value
X-Y angular measurement mode	Enables contactless rotation sensing without external magnets or complex calibration-ideal for multifunction knobs.
Configurable update frequencies	Allows dynamic trade-off between latency and power: e.g., 10 Hz for battery-powered pedals vs. 100 Hz for real-time steering angle.
External µC triggering via I²C	Permits synchronized multi-sensor acquisition and deterministic timing in safety-critical systems.
Interrupt-driven measurement signaling	Reduces MCU wake-up frequency and CPU load compared to periodic polling-critical for low-power ECUs.
Stray field immunity	High ±160 mT full-scale range inherently suppresses interference from nearby motors or solenoids in vehicle cabins.

Applications

Gear Stick Position Sensing

Steering Wheel Control Module

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

IC Role / Device Role / Timing Role: Primary 3D magnetic position transducer interfacing with body control module via I²C.

Use Value: Replaces multiple single-axis sensors or potentiometers, reducing BOM count and improving long-term reliability in high-cycle mechanical interfaces.

Use Scenario: Monitoring rotary encoder inputs on multifunction steering wheel buttons and scroll wheels.

IC Role / Device Role / Timing Role: Angular position sensor providing X-Y directional data for menu navigation and volume control.

Use Value: Enables compact, sealed designs immune to dust/moisture ingress-eliminating wear-prone mechanical contacts.

Pedal Position Feedback

Valve Actuator Monitoring

Use Scenario: Measuring accelerator or brake pedal angle in drive-by-wire systems with functional safety requirements.

IC Role / Device Role / Timing Role: Safety-relevant position sensor feeding redundant signal paths to powertrain ECU.

Use Value: Delivers fail-safe diagnostics (e.g., stuck-at, open-circuit) and meets ASIL-B readiness through built-in self-test capabilities.

Use Scenario: Closed-loop monitoring of linear or rotary valve position in HVAC or engine air management actuators.

IC Role / Device Role / Timing Role: High-accuracy magnetic displacement sensor reporting real-time position to actuator controller.

Use Value: Maintains precision across wide temperature swings (-40°C to 125°C) without recalibration-reducing service intervals.

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
MLX90393EDC-ABB-000-TU	Higher full-scale range (±500 mT), SPI-only interface, no integrated interrupt output.	Better suited for high-field industrial actuators; lacks /INT pin for low-latency event signaling.	Select when SPI infrastructure exists and higher magnetic immunity is required over ultra-low power consumption.
TLE5012BE1000	Resolver-based angle sensor with SINC interface, 16-bit resolution, no I²C support.	Targets high-precision motor control (e.g., EPS), not general-purpose UI controls.	Choose for ASIL-C systems requiring absolute angle accuracy <0.1°, not for cost-sensitive consumer-facing HMI.

Compared with MLX90393 and TLE5012B, the TLE493DA2B6HTSA1 uniquely balances ultra-low standby current (7 nA), I²C + interrupt integration, and automotive temperature range in a 6-pin TSOP6 package-making it optimal for space-constrained, battery-aware human-machine interfaces.

FAQ

What is the default I²C address of the TLE493DA2B6HTSA1?

The device ships with fixed I²C addresses: 0x6A for write operations and 0x6B for read operations. These cannot be changed via hardware pins or software configuration-ensuring predictable bus behavior in multi-sensor networks without address conflict risk.

Does the TLE493DA2B6HTSA1 require external pull-up resistors on SDA/SCL lines?

Yes-both SDA and SCL pins are open-drain and require external pull-up resistors. Recommended values are 1.2 kΩ for standard 3.3 V I²C buses; values must be adjusted based on bus capacitance to meet rise/fall time specifications per I²C standard.

Can the TLE493DA2B6HTSA1 operate without using the /INT pin?

Yes-the /INT pin is optional. In polling mode, the host MCU reads status registers to detect completed measurements. However, omitting /INT increases power consumption and latency, especially in low-duty-cycle applications where interrupt-driven wake-up is critical.

Is the TLE493DA2B6HTSA1 qualified for automotive use?

Yes-it is AEC-Q100 qualified (Grade 0), rated for junction temperatures from -40°C to +125°C, and specified for operation in automotive electrical environments including load dump, reverse battery, and EMC stress per ISO 11452 and ISO 7637 standards.
