Using the magnetic field alert means that the entire microcontroller system can be set to sleep mode, with the sensor only waking the microcontroller and the connected systems when the magnetic position indication changes. This enables the development of systems that save a great deal of energy, but are nevertheless capable of reacting quickly to a change in position.
The TLE493D-W1B6 sensor provides precise and energy-efficient 3D magnetic field detection for various applications. Flexible operating modes offer dedicated and scalable system designs with a wide measurement range for precise position determination and very low power consumption. The integrated magnetic field alert can wake up the microcontroller systems in order to inform them of a change in position.
Development samples of the TLE493D-W1B6 are available. Volume production is planned for the end of 2016.
