TPMS solution - MLX91804
Product description
The product has been designed specifically to improve system SWaP (Size, Weight and Power) performance. Housed in a tiny 14-pin wettable flanks DFN package requiring a mere 20 mm² floor area.
In addition to its small size, the MLX91804 establishes a new benchmark for current consumption helping system designers squeeze even more operating lifetime from small form factor batteries and harvested energy sources.
The MLX91804 offers 16-bit RISC processing coupled with 16 kB of flash memory code space to accommodate sophisticated TPMS algorithms. The product has been developed mindful of next generation smart tire and tire mounted applications. Standard operating temperature range for this part is -40 °C to 125 °C.
