MIC1555 IttyBitty CMOS RC timer / oscillator thiab MIC1557 IttyBitty CMOS RC oscillator yog tsim los muab kev tsheb ciav hlau-rau-rail pulses rau lub sijhawm ncua sijhawm lossis ntau zaus.
Cov khoom siv no zoo sib xws hauv kev ua haujlwm rau tus qauv kev lag luam "555", yam tsis muaj kev tswj hwm zaus (FC) tus pin lossis qhib-collector tso tawm (D) tus pin. Qhov pib tus pin (THR) muaj qhov ua ntej tshaj qhov ua rau (TRG) cov tswv yim, kom ntseeg tau tias BiCMOS cov zis tawm thaum TRG siab.
MIC1555 tuaj yeem siv los ua ib qho astable (oscillator) lossis monostable (ib-shot) nrog rau qhov pib sib cais thiab ua rau cov khoom nkag. Hauv hom txhaj tshuaj ib zaug, qhov tso zis pulse dav yog tswj hwm los ntawm tus neeg sab nraud thiab lub capacitor. Lub sij hawm ncua sij hawm yuav raug tswj xyuas los ntawm microseconds mus rau teev. Hauv hom oscillator, cov zis yog siv los muab cov lus qhia meej, nrog qhov tsawg kawg nkaus ntawm ib qho resistor thiab ib lub capacitor ua 50% lub luag haujlwm voj voog square yoj.
MIC1557 yog tsim los rau kev ua haujlwm astable (oscillator) nkaus xwb, nrog lub nti xaiv / rov pib dua (CS) cov tswv yim rau kev kaw qis qis. Ib qho resistor thiab ib lub capacitor muab 50% lub luag haujlwm voj voog square yoj. Lwm lub luag haujlwm lub voj voog yuav raug tsim los siv ob lub diodes thiab ob lub resistors.
MIC1555/7 yog siv los ntawm +2.7V rau +18V qhov hluav taws xob thiab raug ntsuas rau -40 ° C txog + 85 ° C ambient kub ntau yam. MIC1555/7 muaj nyob rau hauv SOT-23-5, thiab nyias SOT23-5 5-pin pob. Ib qho profile qis, ultra-nyias UTDFN version ntawm MIC1555 (nrog xaiv nti) kuj muaj.
