Abubuwan Abubuwan Kayan Wuta Na Asali Na Asali Mafi Kyawun STC AVR 8254 Microcontroller MCU IC TL2844BDR-8 SOP

Tsarin TL284xB da TL384xB na haɗin haɗin haɗin gwiwar sarrafawa suna ba da fasalulluka waɗanda suka wajaba don aiwatar da tsare-tsare na kashe-layi ko dc-to-dc ƙayyadaddun ƙayyadaddun yanayin yanayin halin yanzu, tare da ƙaramin adadin abubuwan waje.Wuraren da aka aiwatar a ciki sun haɗa da kullewar ƙarancin wuta (UVLO) da madaidaicin tunani wanda aka gyara don daidaito a shigar da ƙararrawa kuskure.Sauran hanyoyin da'irori na ciki sun haɗa da dabaru don tabbatar da aiki mai lalacewa, kwatancen bugun bugun jini (PWM) wanda kuma ke ba da iko mai iyaka na yanzu, da matakin fitarwa na totem-pole wanda aka ƙera don samowa ko nutse babban halin yanzu.Matsayin fitarwa, wanda ya dace da tuki N-tashar MOSFETs, yana da ƙasa kaɗan lokacin da yake cikin kashewa.
Jerin TL284xB da TL384xB sun dace da daidaitattun TL284x da TL384x tare da haɓakawa masu zuwa.An ƙayyadadden lokacin farawa don zama 0.5mA (max), yayin da aka gyara fiddawar oscillator zuwa 8.3 mA (nau'i).Bugu da ƙari, yayin yanayin kullewar ƙarancin ƙarfin lantarki, fitarwar tana da matsakaicin matsakaicin ƙarfin lantarki na 1.2 V yayin nutsewa 10 mA (VCC = 5 V).
Babban bambance-bambance tsakanin membobin waɗannan jerin sune madaidaitan UVLO da matsakaicin jeri na sake zagayowar ayyuka.Matsakaicin UVLO na 16 V (akan) da 10 V (kashe) akan na'urorin TLx842B da TLx844B sun sa su dace da aikace-aikacen layi.Matsakaicin madaidaicin madaidaicin madaidaicin na'urorin TLx843B da TLx845B sune 8.4 V (akan) da 7.6 V (a kashe).Na'urorin TLx842B da TLx843B na iya aiki zuwa hawan keken aiki suna gabatowa 100%.A duty-cycle kewayon 0% zuwa 50% aka samu ta TLx844B da TLx845B da Bugu da kari na ciki toggle flip-flop, wanda blanks da fitarwa kashe duk sauran Agogon cycle.The TL284xB-jerin na'urorin suna halin aiki daga - 40°C zuwa 85°C.TL384xB-jerin na'urorin suna halin aiki daga 0 ° C zuwa 70 ° C.
