TLE493D-A1B6

The TLE493D-A1B6 is Infineon’s 3-axis Hall-effect magnetic sensor (digital) in the TLE493D family. It measures magnetic flux density along X, Y, and Z (Bx, By, Bz) and outputs the data digitally via I2C or SPI. The device integrates three Hall elements with signal conditioning, temperature compensation, offset calibration, and scalable full-scale ranges for stability across temperature. It is designed for automotive-grade, low-power operation in a small footprint, with fast data rates and low standby current. Interfaces include I2C (SDA/SCL) or SPI (SCK, MOSI/MISO, CS) and a configurable bus address. Common applications: non-contact position or speed sensing, rotary encoders, motor commutation, wheel-speed sensors, and 3D magnetic-field sensing in robotics and consumer electronics. The A1B6 suffix denotes a specific package/pinout/quality variant; consult the datasheet for exact pin configuration, supply range, I2C address, and calibration procedures. For best results, follow recommended layout and shielding to minimize stray fields; readings are provided as digital values (often in mT or raw codes) with optional filtering/interrupts.

- 3-axis Hall effect sensor: measures X, Y, Z magnetic flux density with on-chip processing
- Digital output: I2C interface for easy MCU integration (fast data rate and addressable slave)
- On-chip signal conditioning: temperature compensation and offset/gain calibration for stable accuracy over temperature
- Low power consumption and compact footprint suitable for battery-powered/space-constrained designs
- Wide supply voltage and operating temperature for automotive/industrial use
- Automotive-grade (AEC‑qualified) with robust EMI/ESD protection
- Small package suitable for tight assemblies (compact QFN/package options)
- Fault detection and data-ready/status indicators for reliable operation
- Ideal for non-contact position sensing, motor commutation, encoders, and similar magnetic-field sensing applications
Note: exact voltage range, data rate, and package variant can vary by revision; consult the latest datasheet for precise numbers.

The TLE493D-A1B6 is packaged in a 6‑pin LGA (SMD) package, nominally 3.0 × 3.0 × ~0.95 mm.

Pin count: 3 pins (SOT‑23‑3).
Pin functions:
- VCC (supply voltage)
