SN74CB3Q3245 ni umuyoboro mwinshi wa bisi ya FET ikoresha pompe yumuriro kugirango izamure voltage yumuryango wa transistor pass, itanga imbaraga nke kandi ziringaniye kuri leta (ron).Kurwanya hasi no kuringaniza ON-leta irwanya kugabanuka gukabije kandi ishyigikira gari ya moshi-kuri-gari ya moshi guhinduranya amakuru yinjira / ibisohoka (I / O) ibyambu.Igikoresho kirimo kandi amakuru make I / O ubushobozi bwo kugabanya ubushobozi bwo gupakira no kugoreka ibimenyetso kuri bisi yamakuru.Byashizweho byumwihariko kugirango ushyigikire umurongo mugari wa porogaramu, SN74CB3Q3245 itanga igisubizo cyimbere cyimbere gikwiranye numuyoboro mugari, imiyoboro, hamwe na sisitemu yo kubara amakuru.
SN74CB3Q3245 itunganijwe nka 8-bit ya bisi ihinduka hamwe nibisohoka-bishoboza (OE \) ibyinjijwe.Iyo OE \ iri hasi, bisi ihinduka ni ON na A port ihujwe nicyambu B, itanga amakuru yerekanwa hagati yicyambu.Iyo OE \ ari ndende, bisi ihinduka ni OFF kandi leta-impedance ihari hagati yicyambu cya A na B.
Iki gikoresho cyerekanwe neza kubice-imbaraga-hasi-porogaramu ukoresheje Ioff.Umuzunguruko wa Ioff urinda kwangiza ibintu bigenda byinjira mugikoresho iyo bikoreshejwe hasi.Igikoresho gifite akato mugihe cyo kuzimya.
Kugirango hamenyekane leta-impedance nyinshi mugihe amashanyarazi azamutse cyangwa amashanyarazi hasi, OE \ igomba guhambirwa na VCC binyuze mukurwanya gukurura;agaciro ntarengwa ka résistoriste kugenwa nubushobozi-burohama bwa shoferi.

- gucunga amashyuza no kurinda birenze urugero
Imicungire yubushyuhe nindi mbogamizi ikomeye kubashushanya bateri.Buri chip ya charger ihura nigabanuka rya voltage mugihe cyo kwishyuza kubera ubushyuhe.Kugira ngo wirinde kwangirika kwa batiri cyangwa guhagarika sisitemu, charger nyinshi zirimo uburyo bumwe bwo kugenzura uburyo bwo gucunga ubushyuhe.Ibikoresho bishya bikoresha uburyo buhanitse bwo gutanga ibitekerezo kugirango bikomeze bikurikirane ubushyuhe bwurupfu kandi uhindure ibiciro byumuvuduko cyangwa kubara ku kigereranyo kijyanye nimpinduka zubushyuhe bwibidukikije.Ubu bwenge bwuzuye butuma chip ya charger iriho igabanya buhoro buhoro amashanyarazi kugeza igihe uburinganire bwumuriro bugeze kandi ubushyuhe bwo gupfa bukareka kuzamuka.Iri koranabuhanga ryemerera charger guhora yishyuza bateri kumuyoboro mwinshi ushoboka utarinze sisitemu kuzimya, bityo bikagabanya igihe cyo kwishyuza bateri.Ibikoresho byinshi bishya uyumunsi nabyo bizongeramo uburyo bwo kurinda birenze urugero.
Amashanyarazi BQ25616JRTWRtanga ibintu bitandukanye byumutekano mukwishyuza bateri no mubikorwa bya sisitemu, harimo kugenzura ubushyuhe bwa bateri yubushyuhe bwa coeffisente ya termistor, kwishyuza igihe cyumutekano hamwe na volvoltage hamwe nuburinzi burenze urugero.Amabwiriza yubushyuhe agabanya amashanyarazi mugihe ubushyuhe bwihuza burenze 110 ° C.Ibisohoka muri STAT byerekana uko kwishyuza hamwe nibisabwa byose.
Gusaba
Amashanyarazi ya batiri ni ubwoko bwimbaraga zo gucunga amashanyarazi, urwego rusaba ni rugari cyane.Iterambere ryimicungire yamashanyarazi ningirakamaro mugutezimbere imikorere yimashini yose, guhitamo imiyoboro yo gucunga amashanyarazi bifitanye isano itaziguye nibikenewe na sisitemu, mugihe iterambere ryibikoresho bikoresha imiyoboro ya digitale biracyakenewe kurenga imbogamizi yibiciro.
BQ25616 / 616J ni ihuriweho cyane 3-Guhindura uburyo bwa bateri yo guhinduranya hamwe na sisitemu yo gucunga inzira ya sisitemu ya bateri imwe ya Li-Ion na Li-polymer.Igisubizo cyahujwe cyane ninjiza ihindura-guhagarika FET (RBFET, Q1), guhinduranya FET (HSFET, Q2), guhinduranya FET (LSFET, Q3), na batiri FET (BATFET, Q4) hagati ya sisitemu na bateri.Inzira ntoya yingufu zoguhindura imikorere yuburyo bwimikorere, igabanya igihe cyo kwishyuza bateri kandi ikongerera igihe cyo gukora bateri mugihe cyo gusohora.
BQ25616 / 616J ni ihuriweho cyane 3-Imiyoboro ya bateri yo guhinduranya uburyo bwa sisitemu ya sisitemu ya Power Path yo gucunga bateri ya Li-ion na Li-polymer.Iragaragaza kwishyurwa byihuse hamwe nimbaraga nyinshi zinjiza voltage kumurongo mugari wa porogaramu zirimo abavuga, inganda, nubuvuzi bworoshye.Inzira yimbaraga nkeya yinzira itunganya imikorere-yuburyo bukora neza, igabanya igihe cyo kwishyuza bateri, kandi ikongerera igihe cyo gukora bateri mugihe cyo gusohora.Iyinjiza ryumubyigano hamwe nubu bigenga bitanga ingufu ntarengwa zo kwishyuza kuri bateri.
Igisubizo cyahujwe cyane ninjiza ihindura-guhagarika FET (RBFET, Q1), guhinduranya FET (HSFET, Q2), guhinduranya FET (LSFET, Q3), na batiri FET (BATFET, Q4) hagati ya sisitemu na bateri.Ihuza kandi bootstrap diode ya disikuru yo murwego rwo hejuru kugirango igende neza sisitemu.Igenamiterere ryibyuma na status raporo itanga iboneza ryoroshye kugirango ushireho igisubizo.
