11. Description of the MLX90292 functions/blocks
11.1. Filtering
The MLX90292 has a build in filter which takes care of the suppression of the signal noise. For the reason
of trade-off between signal dynamics the filtering is programmable. A FIR filtering will be used for this,
which enables several cut-of frequencies and signal latencies.
11.2. Self Test
The MLX90292 has some build in self-test features, which check the RAM, ROM, EEPROM for its correct
storage function. The MLX90292 has also a watch-dog. The ROM and EEPROM are checked during
operation, this is a background process. The duration of one check is 100ms.
11.3. POR
The POR is needed for the reset of the analog part and digital part of the MLX90292.The POR is supplied
by the internally regulated supply Vdec. There is no built-in delay on the POR circuitry (such as
debouncing), so the POR is designed to put the IC in reset whenever the regulated supply falls below a
specified threshold.
