MIC1555 IttyBitty CMOS RC timer/oscillator le MIC1557 IttyBitty CMOS RC oscillator li etselitsoe ho fana ka maqhubu a terene ho isa ho terene bakeng sa tieho e nepahetseng ea nako kapa ho hlahisa khafetsa.
Lisebelisoa tsena li ts'oana le ts'ebetso ea "555" ea indasteri, ntle le pini ea ho laola maqhubu (FC) kapa pini e bulehileng ea ho bokella (D). The threshold pin (THR) e tla pele ho ho kenya trigger (TRG), ho netefatsa hore tlhahiso ea BiCMOS e tima ha TRG e phahame.
MIC1555 e ka sebelisoa e le astable (oscillator) kapa monostable (e le 'ngoe-shot) e nang le lipehelo tse arohaneng le li-trigger. Ka mokhoa o le mong oa ho thunngoa, bophara ba phallo ea phallo bo laoloa ka nepo ke mohanyetsi oa kantle le capacitor. Ho lieha ha nako ho ka laoloa ka nepo ho tloha ho li-microseconds ho isa ho lihora. Ka mokhoa oa oscillator, tlhahiso e sebelisetsoa ho fana ka maikutlo a nepahetseng, ka bonyane ba mochine o le mong le capacitor e le 'ngoe e hlahisang 50% duty cycle square wave.
MIC1557 e etselitsoe ts'ebetso ea astable (oscillator) feela, ka ho kenya chip select/reset (CS) bakeng sa ho koala matla a tlase. Mohanyetsi o le mong le capacitor e le 'ngoe li fana ka 50% duty cycle cycle wave. Likarolo tse ling tsa potoloho ea mosebetsi li ka hlahisoa ho sebelisoa li-diode tse peli le li-resistors tse peli.
Li-MIC1555/7 li tsamaisoa ho tloha +2.7V ho ea ho +18V motlakase oa phepelo 'me li behiloe ho tloha -40°C ho ea ho +85°C sebaka sa mocheso o tikolohong. Li-MIC1555/7 li fumaneha ho SOT-23-5, le liphutheloana tse tšesaane tsa SOT23-5 5-pin. Boemo bo tlase, mofuta oa UTDFN o mosesaane haholo oa MIC1555 (e nang le khetho ea chip) le ona oa fumaneha.
