Nangona kunjalo, inecandelo langaphandle elisebenzayo: ii-LEDs ezine, i-multiplexer kunye ne-chip ye-accelerometer chip.
"I-MAXM86146 isebenzisa idatha ye-accelerometer ukuhlawulela ii-artifact zokuhamba ezenziwa ngamaxesha athile kwaye ilungiselelwe imiqondiso emibini yokutsala okuluhlaza kwangaxeshanye," yatsho inkampani. “Ezi miqondiso mibini ziluhlaza zinokufezekiswa nokuba zimbini iifotodiode kunye ne-LED enye okanye enye yeefoto kunye ne-LED ezimbini. Ukugcwaliswa kweoksijini kufuna ukusetyenziswa kwee-wavevel ze-LED ezahlukeneyo, ezibomvu kunye ne-IR. Kufuneka babelane ngeefotodiode ezifanayo kunye nomgama wokwahlukana. ”
Imodyuli iqulathe i-MAX86141 yeendlela ezimbini zendlela ye-analogue yangaphambili yesiphelo kunye ne-MAX32664C MCU kunye nesibini se-3.8mm2Iifowuni zePIN.
Kwi-chip-front-chip, ii-19bit ADCs ezingama-19 zifunda ii-photodiode kwaye, nangona ii-LED zingaphandle, kufakwe abaqhubi abathathu be-LED (abafuna uloliwe wabo). Isiphindaphindo sangaphandle siyafuneka kwii-LEDs ukuba yonke imisebenzi enokwenzeka kufuneka yenziwe.
Amandla ombane kwimodyuli sisibonelelo esinye se-1.8V (kunye nonikezelo lwe-LED), kwaye imodyuli ixhasa mna2C kunxibelelwano kwiprosesa yomamkeli. "Ii-algorithms ezihlanganisiweyo zilungelelanisa useto lwangaphambili lwe-analogue yangaphakathi ukwandisa isilinganiselo kumyinge wengxolo ngelixa kuncitshiswa ukusetyenziswa kwamandla ngokusekwe kulwabiwo lomsebenzi" -okugqibela kwenziwa yenye yealgorithms.
Kwi-25 iisampulu / s, isiphelo sangaphambili sifuna i-10μA.
Ikhithi yovavanyo (MAXM86146EVSYS #) iyafumaneka.
