St's new wireless charger bhodhi inonangana nemaindasitiri, ekurapa uye akangwara ekushandisa kumba

St yakaparura Qi isina waya yekuchaja package ine 50W transmitter uye inogamuchira kuti ikurumidze kutenderera kutenderera kwemawaya machaja ekushandisa-simba repamusoro-soro senge zviridzwa zvekurapa, midziyo yemuindasitiri, midziyo yemumba nemakomputa.

Nekutora ST's nyowani isina waya yekuchaja mhinduro, vagadziri vanogona kuunza nyore uye yekuchaja yekumhanyisa yekuchaja isina waya kune maapplication uko simba rekubuda uye kumhanya kwekuchaja kuri kudiwa zvakanyanya.Izvi zvinosanganisira cordless vacuum cleaners, maturusi emagetsi asina tambo, marobhoti anofambiswa nefoni akadai sezvidhori, midziyo yekuendesa mishonga yekurapa, inotakurika ultrasound masisitimu, marambi epasiteji uye mwenje wenhare, maprinta nemascanner.Nekuti tambo, zvinobatanidza, uye yakaoma docking zvigadziriso hazvichadiwe, izvi zvigadzirwa zviri nyore kugadzira, zvakachipa, uye zvinoshanda zvakavimbika.

Iyo STEVAL-WBC2TX50 magetsi transmitter inoshandisa ST Supercharge (STSC) protocol uye ine yakanyanya kubuda simba rinosvika pa50W.STSC ndeye ST yakasarudzika isina waya yekuchaja protocol inochaja nekukurumidza kupfuura yakajairwa isina waya yekuchaja protocol inoshandiswa muma smartphones nezvimwe zvakafanana, zvichibvumira mabhatiri mahombe kuchajwa nekukurumidza.Bhodhi inotsigirawo Qi 1.3 5W Baseline Power Profile (BPP) uye 15W Yakawedzerwa Simba Profile (EPP) yekuchaja modes.St's STWBC2-HP Power transmission system package ndiyo huru pa-board chip uye inobatanidza iyo STM32G071 Arm® Cortex-M0 microcontroller ine RF yakatsaurirwa kumberi kumagumo.Iko kumucheto kunopa chiratidzo chekugadzirisa uye frequency control, inotyaira yakakwira-resolution PWM siginareta pane transmitter, inoshandisa 4.1V kusvika 24V DC magetsi, uye inosanganisira MOSFET gedhi mutyairi uye USB yekuchaja D+/D- interface.Pamusoro pezvo, iyo STWBC2-HP system package SiP inogona kupetwa neST's STSAFE-A110 yekuchengetedza unit kuti ipe QI-inoenderana mudziyo ongororo.

Iyo STEVAL-WLC98RX magetsi inogamuchira bhodhi inogona kubata magetsi ekuchaja kusvika pa50W, zvakachengeteka uye nekuvimbika inotsigira kushanda kwakazara kweSTSC neBPP uye EPP yekuchaja modhi.Iyo Adaptive rectifier configuration (ARC) inowedzera chinhambwe chekuchaja kusvika pa50%, ichivhura mukana wekushandisa macoil ane mutengo wakaderera uye mamwe anochinjika masisitimu.Iyo inogamuchira bhodhi inopawo chaiyo voltage-yazvino kuyerwa kwekuonekwa kwechinhu chekunze (FOD), manejimendi ekupisa uye kuchengetedza system.St's STWLC98 isina waya yekuchaja inogamuchira chip ndiyo huru pane-bhodhi chip, ine Cortex-M3 musimboti uye yakanyatsobatanidzwa, inoshanda synchronous rectifier simba nhanho ine inogadziriswa inobuda voltage kusvika ku20V.
