Product Sumo
Iyo SN74CB3Q3245 ndeye yakakwira-bandwidth FET bhazi switch inoshandisa pombi yekuchaja kusimudza gedhi voltage yepass transistor, ichipa yakaderera uye flat ON-state kuramba (ron).Iyo yakaderera uye yakapfava ON-nyika kuramba inobvumira kushoma kuparadzira kunonoka uye inotsigira njanji-kune-njanji switching pane data yekupinda / kubuda (I/O) madoko.Chishandiso ichi zvakare chine yakaderera data I / O capacitance kuderedza capacitive kurodha uye chiratidzo chinokanganisa pane data bhasi.Yakarongedzerwa kutsigira yakakwirira-bandwidth application, iyo SN74CB3Q3245 inopa yakagadziridzwa interface mhinduro inokodzera Broadband kutaurirana, networking, uye data-yakanyanya computing masisitimu.
Iyo SN74CB3Q3245 yakarongeka se8-bit bhazi switch ine imwechete inoburitsa-inogonesa (OE\) yekuisa.Kana OE\ yadzikira, switch yebhazi INOVANYA uye A port yakabatana neB port, ichibvumira bidirectional data kuyerera pakati pezviteshi.Kana OE \ yakakwira, switch yebhazi INODZIMWA uye yakakwira-impedance state iripo pakati peA neB ports.
Ichi chishandiso chakanyatso kutsanangurwa kune chikamu-simba-pasi maapplication uchishandisa Ioff.Ioff circuitry inodzivirira kukuvadza ikozvino backflow kuburikidza nemudziyo kana ichiiswa pasi.Chishandiso chine chekuzvimiririra panguva yekudzima magetsi.
Kuti ive nechokwadi chepamusoro-impedance mamiriro panguva yekusimudza simba kana simba pasi, OE \ inofanirwa kusungirirwa kuVCC kuburikidza nekudhonza resistor;iyo shoma kukosha kwekupikisa inotarirwa nezvino-kunyura kugona kwemutyairi.

Product Benefits
- thermal management uye overvoltage kuchengetedzwa
Thermal manejimendi nderimwe dambudziko rakakura kune vanogadzira bhatiri charger.Yese charger chip inosangana nekudonha kwevoltage panguva yekuchaja nekuda kwekupisa.Kuti udzivise kukuvara kwebhatiri kana kudzima system, machaja mazhinji anosanganisira imwe nzira yekudzora magadzirirwo ekugadzirisa kupisa-up.Midziyo mitsva inoshandisa hunyanzvi hwekuita mhinduro kuenderera mberi nekutarisa tembiricha yekufa uye kugadzirisa chaji iripo zvine simba kana nekuverenga pamwero wakaenzana neshanduko yeambient tembiricha.Iyi yakavakirwa-mukati hungwaru inobvumira yazvino charger chip kuti zvishoma nezvishoma ideredze kuchaja ikozvino kusvika thermal equilibrium yasvika uye tembiricha yekufa yamira kukwira.Iyi tekinoroji inobvumira charger kuti irambe ichichaja bhatiri panguva inokwanisika pasina kuita kuti sisitimu ivhare, nokudaro kuderedza nguva yekuchaja bhatiri.Mazhinji maturusi matsva nhasi anozowedzerawo overvoltage kuchengetedza michina.
Iyo charger BQ25616JRTWRinopa akasiyana maficha ekuchaja bhatiri uye masisitimu mashandiro, kusanganisira bhatiri rakashata tembiricha coefficient thermistor yekutarisa, kuchaja kuchengetedza timer uye overvoltage uye over-ikozvino dziviriro.Thermal regulation inoderedza kuchaja ikozvino kana tembiricha yejunction inopfuura 110 ° C.Iyo STAT inobuda inoshuma mamiriro ekuchaja uye chero mamiriro ekukanganisa.
Application Scenarios
Iyo bhatiri charger chip ndeyemhando yesimba manejimendi chip, iyo application renji yakakura kwazvo.Kuvandudzwa kwesimba rekutonga machipisi kwakakosha mukuvandudza mashandiro emuchina wese, kusarudzwa kwesimba rekutonga machipisi kune hukama zvakananga nezvinodiwa nehurongwa, ukuwo kuvandudzwa kwedhijitari magetsi ekutonga machipisi kuchiri kuda kuyambuka mubhadharo.
Iyo BQ25616/616J yakanyatsobatanidzwa 3-A switch-mode bhatiri yekuchaja manejimendi uye sisitimu simba nzira yekutonga mudziyo weimwe sero Li-Ion uye Li-polymer mabhatiri.Mhinduro yacho yakanyatsobatanidzwa nekuisa reverse-kuvharira FET (RBFET, Q1), yakakwirira-side switching FET (HSFET, Q2), yakaderera-side switching FET (LSFET, Q3), uye bhatiri FET (BATFET, Q4) pakati pehurongwa uye bhatiri.Iyo yakaderera impedance simba nzira inogonesa switch-mode kushanda zvakanaka, inoderedza bhatiri yekuchaja nguva uye inowedzera bhatiri kumhanya nguva panguva yekuburitsa chikamu.
Iyo BQ25616/616J yakanyatsobatanidzwa 3-A switch-mode bhatiri yekuchaja manejimendi uye system Power Path manejimendi mudziyo weLi-ion uye Li-polymer mabhatiri.Iyo inoratidzira kukurumidza kuchaja ine yakakwira yekuisa voltage tsigiro kune akasiyana maapplication anosanganisira vatauri, maindasitiri, uye zvekurapa zvinotakurika zvishandiso.Yayo yakaderera impedance simba nzira inogonesa switch-mode kushanda zvakanaka, inoderedza bhatiri yekuchaja nguva, uye inowedzera bhatiri kumhanya nguva panguva yekuburitsa chikamu.Yayo yekupinza voltage uye yazvino regulation inopa yakanyanya kuchaja simba kubhatiri.
Mhinduro yacho yakanyatsobatanidzwa nekuisa reverse-kuvharira FET (RBFET, Q1), yakakwirira-side switching FET (HSFET, Q2), yakaderera-side switching FET (LSFET, Q3), uye bhatiri FET (BATFET, Q4) pakati pehurongwa uye bhatiri.Iyo zvakare inosanganisa iyo bootstrap diode yeyakakwira-parutivi gedhi dhizaini yekurerutsa system dhizaini.Iyo Hardware kuseta uye chimiro chirevo chinopa nyore kumisikidza kumisikidza mhinduro yekuchaja.
