Asalka TPS23861PWR Beddel TSSOP-28 Isboortiga Isku-dhafka Wareega Chip IC Qaybaha Elektarooniga ah ee Muuqaalka

sharaxaad gaaban:

TPS23861 waa sahlan tahay in la isticmaalo, dabacsanaan, IEEE802.3at PSE xal.Sida loo raro, waxay si toos ah u maamushaa afar dekedood oo 802.3at ah iyada oo aan loo baahnayn wax xakameyn dibadeed.
TPS23861 waxay si toos ah u ogaataa Aaladaha Awooda leh (PDs) ee leh saxeex ansax ah, waxay go'aamiyaan shuruudaha awooda iyadoo loo eegayo kala soocida oo waxay ku dabaqdaa awooda.Kala soocida laba dhacdo ayaa lagu taageeray nooca-2 PDs.TPS23861 waxay taageertaa kala goynta DC iyo qaab dhismeedka FET dibadda ah wuxuu u oggolaanayaa naqshadeeyayaasha inay isku dheelitiraan cabbirka, hufnaanta iyo shuruudaha kharashka.

Faahfaahinta Alaabta

Tags Product

Xakamaynta korantada gudaha ayaa u oggolaanaysa hawlgalka hal tareen.Horumarin ayaa lagu sameeyay HRPWM si loogu ogolaado kontoroolka laba geesoodka ah (habaynta soo noqnoqda).Isbarbardhigga Analog oo leh tixraacyo gudaha 10-bit ah ayaa lagu daray waxaana si toos ah loogu wareejin karaa si loo xakameeyo wax soo saarka PWM.ADC waxay ka beddeshaa 0 ilaa 3.3-V baaxad buuxda oo go'an waxayna taageertaa tixraacyada cabirka-metric VREFHI/VREFLO.Interface-ka ADC waxa loo hagaajiyay korka hoose iyo daahitaanka.

PoE & PSE

PoE waxa kale oo loo yaqaan Power over Ethernet (PoL, Power over LAN) ama Active Ethernet, ama mararka qaarkood si fudud sida Power over Ethernet.
Codsiyada caadiga ah ee PoE waxaa ka mid ah la socodka amniga, telefonka IP-ga, iyo meelaha laga galo wireless-ka (WAPs).Qalabka martida loo yahay ama dhexdhexaadka ah ee loo isticmaalo in lagu bixiyo koronto waa qalabka korontada (PSE).
Nidaamka PoE ee lagu xakameynayo awoodda culeyska ee u dhexeeya PSE iyo PD waxaa lagu qeexay heerka IEEE 802.3bt.Transformer ayaa looga baahan yahay dekedda martida loo yahay ee Ethernet, bartamaha, iyo goobaha xuddunta si xogta loo geliyo fiilada.Intaa waxaa dheer, danab DC ah ayaa lagu dabaqi karaa tuubada dhexe ee beddelka iyada oo aan saameyn ku yeelan calaamadaha xogta.Sida khadka gudbinta korantada kasta, tignoolajiyadani waxay isticmaashaa danab aad u sarreeya (qiyaastii 50V) si ay u ilaaliso heerka hoose ee hadda oo loo yareeyo saameynta hoos u dhaca korantada IR ee khadka, sidaas darteed ilaalinta gaarsiinta tamarta culeyska.Lammaanaha caadiga ah ee 2-siliga ah ee PoE waxa uu keenaa ku dhawaad 13W Fasalka 1 PDs iyo ku dhawaad 25.5W ilaa fasalka 2 PDs, halka labada lamaane ee 4-fire PoE ay awood u yeelan doonaan in ay gaadhsiiyaan ku dhawaad 51W Fasalka 3 PDs iyo ku dhawaad 71W ilaa fasalka 4 PDs.

Heerarka

Saddexda heer ee sahayda korantada ee PoE
1. EEE802.3af Halbeegyada sahayda korontada ee ugu weyn.
Danab DC inta u dhaxaysa 44 iyo 57V, qiimaha caadiga ah waa 48V.Waqtigan xaadirka ah ee hawlgalka caadiga ah waa 10 ilaa 350mA, awoodda wax soo saarka caadiga ah: 15.4W.ogaanshaha xad-dhaafka ah hadda waa 350 ilaa 500mA.Marka la eego xaaladaha wax-load-ka, ugu badnaan hadda loo baahan yahay waa 5mA.afar heerar heerar codsi koronto koronto ah oo ka socda 3.84 ilaa 12.95W ayaa la siiyaa aaladaha PD.
IEEE802.3af qiyaasaha kala soocida.
Aaladaha heerka 0 waxay u baahan yihiin ugu badnaan awoodda hawlgalka ee 0 ilaa 12.95W.
Aaladaha heerka 1 waxay u baahan yihiin ugu badnaan awoodda hawlgalka ee 0 ilaa 3.84W.
Qalabka Class2 wuxuu u baahan yahay awood shaqaynaysa inta u dhaxaysa 3.85W iyo 6.49W.
Qalabka Class3 waxay u baahan yihiin awood kala duwan oo ah 6.5 ilaa 12.95W.
2. IEEE802.3at (PoE+) Halbeegyada korontada ugu muhiimsan.
Danabka DC wuxuu u dhexeeyaa 50 iyo 57V, qiimaha caadiga ah waa 50V.Waqtigan xaadirka ah ee caadiga ah waa 10 ilaa 600mA, awoodda wax soo saarka ee caadiga ah: waa 30W.Qalabka ku shaqeeya PD wuxuu taageeraa kala soocida Class4.

IEEE802.3bt (PoE++)

Qeexida 802.3bt waxay soo bandhigaysaa afar qaybood oo awood sare leh oo PD ah (Fasalka), taasoo keenaysa tirada guud ee fasallada sifada sagaal.Fasalka 5 ilaa 8 waxay ku cusub yihiin heerka PoE waxayna u turjumayaan heerarka awooda PD ee 40.0W ilaa 71W.

802.3bt waa gadaal u jaan qaada 802.3at iyo 802.3af.Awood hoose 802.3at ama 802.3af PD waxaa lagu xidhi karaa awood sare 802.3bt PSE dhib la'aan.Iyo marka awooda sare ee 802.3bt PD ay ku xidhan tahay awooda hoose ee 802.3at ama 802.3af PSE, PD-yadu waxay si fudud ugu baahan yihiin inay awood u yeeshaan inay ka hawlgalaan dawladahooda hoose ee awooda, taas oo loo yaqaan "Degradation".
