Podzespoły  BMA400 - czujnik przyśpieszenia 


Firma Bosch Sensortec wprowadza do oferty czujnik przyśpieszenia BMA400. Zgodnie z informacją podaną przez producenta, układ wymaga do zasilania 10-krotnie mniejszy prąd, niż oferowane dotychczas odpowiedniki. Wynosi on poniżej 1 µA w trybie uśpienia, do 4 µA w trybie pracy licznika kroków i do 14 µA przy pełnej funkcjonalności.

BMA400 ma wbudowany niskoszumny regulator napięcia, co pozwala m.in. na uzyskanie stabilnych parametrów w szerokim zakresie napięcia zasilania. Dodatkowym atutem jest pamięć FIFO o pojemności aż 1 kB.

Dzięki specjalnym algorytmom układ dobrze rozróżnia wibracje od sytuacji realnych zagrożeń, takich jak np. stłuczenie szyby, co ma duże znaczenie dla aplikacji h czujników w systemach alarmowych.

Miniaturowa obudowa (2,0 mm×2,0 mm×0,95 mm) oraz niewielki pobór energii predysponują układ przed wszystkim do zastosowania w urządzeniach przenośnych oraz IoT.
