Several motion detection strategies can be implemented on the MLX90603: The MLX90603 has several
IO’s, some with interrupt capability. Wake-up from shelf or sleep mode can be realized using the interrupt
IO’s.
The IC coil inputs can be used for LF initiation (measurement on demand). Typically the 125 KHz LF field is
detected when the tire module rotates and comes close to the LF initiator in the wheel well. The wheel
rotation can be detected fast and with low power, if the coil input sensing is programmed with a low duty
cycle (e.g. duty cycle of 10% , 1ms on - 9ms off).
An alternative approach for very sensitive LF initiation is that the MLX90603 powers and measures an
external LF detection IC that uses two LF antennas.
7.7.1 Tools
The MLX16 environment is based on the EMLX-MM emulator/programmer tool, in combination with a C
compiler.
7.7.2 Standard library
A set of library functions is available to simplify the programming of the total application. A range of
application notes describe the software examples.
