Infineon Technologies TLE493DA1B6HTSA1

Overview

TLE493DA1B6HTSA1 from Infineon Technologies is an automotive-qualified 3D Hall-effect magnetic sensor in TSOP6 package, delivering simultaneous Bx/By/Bz field measurements with ±60 mT range, 12-bit resolution per axis, and integrated temperature sensing. It operates from 2.9 V to 3.5 V, supports I²C interface (7-bit address configurable via ADDR pin), and targets rotary/linear position sensing in gear sticks, multi-function knobs, and pedal/valve systems.

For engineers reviewing the TLE493DA1B6HTSA1 datasheet, TLE493DA1B6HTSA1 pinout, TLE493DA1B6HTSA1 application, or TLE493DA1B6HTSA1 equivalent, key selection criteria include ultra-low active current (5 µA @ 6 Hz), 7 nA power-down mode, interrupt-driven measurement completion signaling, and automotive-grade operation from −40 °C to +125 °C junction temperature.

Technical Context

The device integrates three spinning vertical Hall plates (X/Y) and a lateral Hall plate (Z) with sequential multiplexing into a single 12-bit SAR ADC. Its power mode control unit features dual oscillators - a low-power oscillator for timing in sleep modes and a fast oscillator activated during measurement cycles - enabling dynamic update rate configuration without external clocking.

Measurement sequencing is fully managed internally: after power-up or I²C wake command, it sequentially samples Bx, By, Bz, then optionally temperature (enabled by default), all synchronized to internal timing. The /INT pin asserts open-drain low upon data readiness, eliminating polling overhead in microcontroller-based systems.

FAQ

What is the I²C address configuration method for TLE493DA1B6HTSA1?

The I²C slave address is determined by the logic level on the SDA/ADDR pin at power-up: low = 0x1E, high = 0x1F. This configuration is latched internally and remains fixed until next power cycle. No register write is needed to set the address, simplifying initialization in multi-sensor systems.

Does TLE493DA1B6HTSA1 require external components for basic operation?

Only two external components are mandatory: a 100 nF ceramic decoupling capacitor between VDD and Pin 2 GND, and pull-up resistors (typically 4.7 kΩ) on SCL and SDA lines. No external oscillator, reference, or calibration circuitry is required - all timing and compensation are handled on-chip.

How does the /INT pin function during continuous measurement mode?

In continuous mode, /INT asserts low for ≥1 µs each time a full measurement cycle (Bx, By, Bz, and optional temperature) completes and new data is written to output registers. The pin releases high immediately after, allowing edge-triggered interrupts on microcontroller GPIO pins without debouncing.

Can TLE493DA1B6HTSA1 operate reliably in high-vibration environments like engine compartments?

Yes - it is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) and tested for mechanical shock (1000 g) and random vibration (20–2000 Hz, 20 g rms). The monolithic silicon design and TSOP6 package eliminate moving parts and solder joint fatigue risks common in electromechanical sensors.
