Infineon TLE493D - 3D magnetic sensor family

TLE493D family of 3D magnetic sensors for consumer, industrial and automotive applications

Infineon 3D magnetic sensor

Infineon’s new 3D magnetic sensor family TLE493D offers accurate three dimensional sensing with extremely low-power consumption. Within its small 6-pin package the sensor provides direct measurement of the x-, y-, and z components of a magnetic field.

The sensor family is ideally suited for the measurement of:

  • 3 dimensional movement within a magnetic field
  • Linear slide movement
  • 360° angle rotation

By combining 3-axis measurement in a small package, with low power consumption, the TLE493D sensors provide a contactless position sensing alternative to applications which traditionally use mechanical or optical solutions. The system size for these applications can be reduced as magnetic threshold stability over temperature provides a highly accurate and more robust solution for those systems.

Infineon’s sensor provides a standard 2-wire digital I²C communication interface, which enables a bi-directional communication between the sensor and microcontroller. 

Key features

  • 3-dimensional magnetic field sensing (Bx, By and Bz)
  • Integrated temperature sensing
  • Low-current consumption
    • 7 nA in power down mode
    • 10 µA in low power operation at 50 Hz
  • 2.8 to 3.5 V operating supply voltage
  • Digital output via 2-wire standard I2C interface
  • Bx, By and Bz linear field measurement up to ±160 mT
  • 12-bit data resolution for each measurement direction
  • Resolution 130 µT/LSB (optional 65 µT/LSB)
  • Sample rate 0.04 … 8.4 KHz
  • TSOP6 package
  • Operating temperature range from -40°C to 125°C
