I-LP87702DRHBRQ1 Ikhwalithi ephezulu Yezinto Ezintsha&Zoqobo ze-IC Edidiyelwe Yezingxenye Zogesi Zesekethe Esitokweni

I-LP87702DRHBRQ1 Ikhwalithi Ephezulu Entsha&Yoqobo Izingxenye Zogesi Zesekethe Ehlanganisiwe ye-IC Esitokweni Esifakiwe

incazelo emfushane:

I-LP87702-Q1 isiza ukuhlangabezana nezidingo zokuphathwa kwamandla zamapulatifomu akamuva, ikakhulukazi ku-radar yezimoto kanye nezinhlelo zokusebenza ze-radar zekhamera nezezimboni.Idivayisi iqukethe iziguquli ezimbili eziya phansi ze-DC/DC, kanye nesiguquli se-boost esingu-5-V ukuze sisekele izinhlelo zokusebenza ezibalulekile zokuphepha.Idivayisi ihlanganisa okokufaka kokuqapha kwamandla kagesi okubili kokunikezwa kwamandla angaphandle kanye ne-watchdog yewindi.
Ukusebenza okuzenzakalelayo kwe-PWM/PFM (imodi ye-AUTO) kunikeza ukusebenza kahle okuphezulu ngaphezu kwebanga elibanzi lokuphumayo lamanje labaguquli bebhaka.I-LP87702-Q1 isebenzisa inzwa ye-voltage ekude ukunxephezela ukwehla kwe-IR phakathi kokuphuma kwesiguquli nendawo yokulayisha, ngaleyo ndlela ithuthukise ukunemba kwe-voltage ephumayo.

I-PMIC?

I. Yini i-PMIC
I-PMIC isifinyezo se-IC yokuphathwa kwamandla, isici esiyinhloko idigri ephezulu yokuhlanganisa, iphakheji evamile yokukhipha amandla amaningi ku-chip ukuze isimo sohlelo lokusebenza lwamandla amaningi sibe nokusebenza kahle okuphezulu, nosayizi omncane.Ama-PMIC avame ukusetshenziswa ezinhlelweni ze-CPU, njengedizayini ye-set-top box, idizayini yesipikha sezwi ehlakaniphile, idizayini enkulu yemishini yokulawula yezimboni, njll.
I-PMIC eyodwa ingaphatha izinsiza eziningi zamandla zangaphandle, yenze imephu yezidingo zesistimu eyahlukene kuvoltheji ephumayo yesilawuli.Angasetshenziswa futhi kumaphrosesa ahlukahlukene, izilawuli zesistimu, kanye nezinhlelo zokusebenza zokugcina, ezidinga kuphela izinguquko kuzilungiselelo zerejista ezifanele noma i-firmware, ngaphandle kwesidingo sokuklama kabusha isekethe entsha ehlanganisiwe (IC).

Imakethe ye-PMIC ikhula ngokugxumagxuma nemingcele ngenxa yezitayela zamanje ezimbalwa.Enye inkambiso ukuphishekela komthengi ukuhambahamba okungenantambo, okudale isidingo esikhulu samadivayisi amancane, asebenza ngamabhethri kanye nesidingo esiwumphumela sezixazululo zokuphatha amandla ezididiyelwe kakhulu.
Ngesikhathi esifanayo, kunesidingo esikhulayo esivela kubathengi nabakhiqizi bemikhiqizo eyonga amandla futhi enciphisa ukukhishwa kwekhabhoni.Ukuthambekela "okuluhlaza" emhlabeni wonke kukhuphule isidingo semikhiqizo ye-elekthronikhi ngokuphathwa kwamandla okuphumelelayo, okwenza ukuphathwa kwamandla kube isici esibaluleke kakhulu nesithandwa kakhulu.

Imisebenzi Esemqoka

Imisebenzi esemqoka ye-PMIC: [ukuphathwa kwamandla, ukulawula ukushaja, ukushintshwa komjikelezo wokulawula]

- Isiguquli se-DC-DC
- I-Low Dropout Voltage Regulator (LDO)
- Ishaja yebhethri
- Ukukhetha kokuphakelwa kwamandla
- Ukulawulwa kwamandla kagesi anamandla
- Ukuvula/ukuvala ukulawulwa kokulandelana kokunikezwa kwamandla ngakunye
- Ukutholwa kwe-Voltage ngayinye kagesi
- Ukutholwa kwezinga lokushisa
- Eminye imisebenzi

Uma i-PMIC inawo amandla amaningi, lapho amandla kagesi etholakala kumamojula ohlelo ahamba kahle, kuyancipha ukunikezwa kwamandla kwemojula ngayinye, ngakho-ke ukonga amandla amaningi.
