MIC1557YM5-TR Nā Manawa & Nā Huahana Kākoʻo 2.7V a i 18V, '555′ RC Timer/Oscillator me ka Paʻa

• + 2.7V a +18V Hana

• Haʻahaʻa i kēia manawa - <1 μA Keʻano hoʻopiʻi maʻamau (MIC1557) - 200 μA maʻamau (TRG a me THR Low) ma 3V Supply

• Ka manawa mai Microseconds a i nā hola

• "Zero" Leakage Trigger and Threshold Inputs

• 50% Wave Square me hoʻokahi mea pale, hoʻokahi kapasitor

• ʻOi aku ka mua o ka hoʻokomo ʻana i ka paepae

• <15Ω Huakaʻi ma ke kūʻē

• ʻAʻohe Output Cross-Conduction Current Spikes

• <0.005%/°C Paʻa Paʻa

• <0.055%/V Paa Paa • 10-pin Ultra-Thin DFN Pūʻolo (2 mm × 2 mm × 0.4 mm)

• SOT-23-5 liʻiliʻi ma luna mauna pūʻolo

Hoʻolālā ʻia ka MIC1555 IttyBitty CMOS RC timer/oscillator a me MIC1557 IttyBitty CMOS RC oscillator no ka hāʻawi ʻana i nā pulse rail-to-rail no ka lohi o ka manawa a i ʻole ka hana pinepine.

Ua like kēia mau mea hana me ka maʻamau o ka ʻoihana "555", me ka ʻole o ka pine control frequency (FC) a i ʻole kahi pine hōʻiliʻili wehe (D). Aia ka pine paepae (THR) ma mua o ke kumu hoʻokomo (TRG), e hōʻoia ana i ka pau ʻana o ka puka BiCMOS ke kiʻekiʻe ka TRG.

Hiki ke hoʻohana ʻia ka MIC1555 ma ke ʻano he astable (oscillator) a i ʻole monostable (hoʻokahi-pana) me ka paepae kaʻawale a me nā mea hoʻokomo. Ma ke ʻano pana hoʻokahi, hoʻomalu pono ʻia ka laula pulse puka e kahi resistor waho a me kahi capacitor. Hiki ke hoʻomalu pono ʻia nā manawa lohi mai nā microseconds a i nā hola. Ma ke ʻano oscillator, hoʻohana ʻia ka hoʻopuka e hāʻawi i nā manaʻo kūpono, me ka liʻiliʻi o hoʻokahi pale a me hoʻokahi capacitor e hana ana i ka nalu huinahā 50% duty cycle.

Hoʻolālā ʻia ka MIC1557 no ka hana astable (oscillator) wale nō, me ka hoʻokomo ʻana i kahi chip koho/reset (CS) no ka pani haʻahaʻa haʻahaʻa. Hoʻokahi mea pale a me hoʻokahi capacitor hāʻawi i 50% duty cycle square wave. Hiki ke hana ʻia nā lākiō ʻē aʻe me ka hoʻohana ʻana i ʻelua diodes a me ʻelua mau mea pale.

Hoʻohana ʻia ka MIC1555/7 mai ka + 2.7V a i ka + 18V lako uila a ua helu ʻia no -40°C a +85°C ambient temperature range. Loaʻa ka MIC1555/7 ma SOT-23-5, a me nā pūʻolo 5-pin lahilahi SOT23-5. Loaʻa pū kekahi ʻano haʻahaʻa haʻahaʻa, ultra-thin UTDFN o ka MIC1555 (me ke koho chip).
