Kufotokozera mwachidule:

TPS23861 ndiyosavuta kugwiritsa ntchito, yosinthika, IEEE802.3at PSE yankho.Monga kutumizidwa, imangoyendetsa madoko anayi a 802.3at popanda kufunikira kwa kuwongolera kulikonse.
TPS23861 imazindikira zokha Zida Zamagetsi (PDs) zomwe zili ndi siginecha yovomerezeka, zimazindikira zofunikira zamphamvu malinga ndi gulu ndikugwiritsa ntchito mphamvu.Gulu la zochitika ziwiri limathandizidwa ndi mtundu wa 2 PD.TPS23861 imathandizira kuyimitsidwa kwa DC ndipo mamangidwe akunja a FET amalola opanga kuti azitha kulinganiza kukula, kuchita bwino komanso zofunikira zothetsera mavuto.

Wowongolera magetsi wamkati amalola kuti pakhale njanji imodzi.Zowonjezera zapangidwa ku HRPWM kuti zilole kulamulira kwapawiri (kusinthasintha kwafupipafupi).Zofananira za analogi zomwe zili ndi zolozera zamkati za 10-bit zawonjezedwa ndipo zitha kuyendetsedwa mwachindunji kuwongolera zotuluka za PWM.ADC imasintha kuchokera ku 0 kupita ku 3.3-V yokhazikika pamlingo wathunthu ndipo imathandizira zolozera za VREFHI/VREFLO.Mawonekedwe a ADC adakongoletsedwa kuti akhale otsika kwambiri komanso latency.

PoE & PSE

PoE imadziwikanso kuti Power over Ethernet (PoL, Power over LAN) kapena Active Ethernet, kapena nthawi zina kungoti Power over Ethernet.
Ntchito zodziwika bwino za PoE zimaphatikizapo kuyang'anira chitetezo, IP telephony, ndi malo opanda zingwe (WAPs).Chipangizo chogwiritsira ntchito kapena chapakati chapakati chomwe chimagwiritsidwa ntchito popereka mphamvu ndi zipangizo zamagetsi (PSE) .Katundu wolumikizidwa ku cholumikizira cha Efaneti ndi chipangizo chamagetsi (PD).
Protocol ya PoE yowongolera mphamvu yolemetsa pakati pa PSE ndi PD imatanthauzidwa ndi muyezo wa IEEE 802.3bt.Transformer ikufunika pa doko la Ethernet host, midspan, ndi malo apakati kuti abweretse deta mu chingwe.Kuphatikiza apo, magetsi a DC angagwiritsidwe ntchito pampopi wapakati wa thiransifoma popanda kukhudza chizindikiro cha data.Mofanana ndi chingwe chilichonse chotumizira mphamvu, teknolojiyi imagwiritsa ntchito magetsi okwera kwambiri (pafupifupi 50V) kuti ikhale yochepa komanso kuchepetsa mphamvu ya IR voltage dontho mu mzere, motero kusunga mphamvu yoperekera katundu.Mawaya awiri a PoE amapereka pafupifupi 13W ku Class 1 PDs ndi pafupifupi 25.5W ku Class 2 PDs, pamene mawaya 4 a PoE azitha kupereka pafupifupi 51W ku Class 3 PDs ndi pafupifupi 71W ku Class 4 PDs.

Miyezo

Miyezo itatu yamagetsi a PoE
1. EEE802.3af Magawo akuluakulu amagetsi.
Mphamvu ya DC pakati pa 44 ndi 57V, mtengo wake ndi 48V.wamba ntchito panopa ndi 10 kuti 350mA, mphamvu linanena bungwe: 15.4W.Kuzindikira kwachulukira ndi 350 mpaka 500mA.Popanda katundu, kuchuluka komwe kumafunikira ndi 5mA.Magawo anayi ofunsira mphamvu zamagetsi kuchokera pa 3.84 mpaka 12.95W amaperekedwa pazida za PD.
Magawo a IEEE802.3af
Zida za Class0 zimafuna mphamvu yopitilira 0 mpaka 12.95W.
Zida za Class1 zimafuna mphamvu yopitilira 0 mpaka 3.84W.
Zida za Class2 zimafuna mphamvu yogwiritsira ntchito pakati pa 3.85W ndi 6.49W.
Zida za Class3 zimafuna mphamvu yapakati pa 6.5 mpaka 12.95W.
2. IEEE802.3at (PoE +) Magawo akuluakulu amagetsi.
Mphamvu ya DC ili pakati pa 50 ndi 57V, mtengo wake ndi 50V.Zomwe zimagwira ntchito ndi 10 mpaka 600mA, mphamvu yotulutsa: ndi 30W.PD yoyendetsedwa ndi chipangizo imathandizira gulu la Class4.

IEEE802.3bt (PoE++)

Mafotokozedwe a 802.3bt amabweretsa magulu anayi atsopano amphamvu kwambiri a PD (Kalasi), kubweretsa chiwerengero chonse cha makalasi amodzi mpaka asanu ndi anayi.Kalasi 5 mpaka 8 ndi atsopano ku muyezo wa PoE ndipo amamasulira mumagulu amphamvu a PD a 40.0W mpaka 71W.

802.3bt ndi kumbuyo n'zogwirizana ndi 802.3at ndi 802.3af.Mphamvu yotsika 802.3at kapena 802.3af PD ikhoza kulumikizidwa ndi mphamvu yapamwamba 802.3bt PSE popanda mavuto.Ndipo pamene mphamvu yapamwamba 802.3bt PD ikugwirizana ndi mphamvu yochepa 802.3at kapena 802.3af PSE, ma PD amangofunika kuti athe kugwira ntchito m'madera awo apansi, omwe amatchedwa "kuwonongeka".
