2.1 Izici zomkhiqizo

Umkhiqizo we-DW03 uyisisombululo esihlanganisiwe kakhulu sokuvikela amaphakethe ebhethri aphinde ashajwe e-lithium-ion/lithium polymer aneseli elilodwa. I-DW03 ifaka i-MOSFET enamandla athuthukisiwe, amasekethe okuthola amandla aphezulu, kanye namasekethe okulibazisa.

 

I-DW03 inikeza yonke imisebenzi yokuvikela ibhethri edingekayo njengokushaja ngokweqile, ukukhipha ngokweqile, ugesi ongaphezulu, kanye ne-short circuit, ngokusetshenziswa kwamandla okuphansi kakhulu ngesikhathi sokusebenza. Le chip ayiklanyelwe kuphela omakhalekhukhwini kodwa futhi ifanelekela zonke izinhlobo zemikhiqizo yolwazi edinga amabhethri ashajwayo e-lithium-ion noma e-lithium polymer ukuze anikezwe amandla isikhathi eside.

 

2.2

I-DW03 iqapha i-voltage yebhethri kanye nogesi, futhi ivikela ibhethri le-lithium eliphinde lishajwe eliyiseli elilodwa ekulimaleni ngenxa ye-voltage yokushaja ngokweqile, i-voltage yokushaja ngokweqile, i-current yokushaja ngokweqile, i-current yokushaja ngokweqile, kanye ne-short circuit ngokunqamula ishaja noma umthwalo. Uhlelo lune-circuit yangaphandle elula. I-MOSFET yakhelwe ngaphakathi, enokumelana okuvamile okulinganayo okungu-65mΩ.

 

3.1 Ukutholwa kweshaja; Umsebenzi wokushaja ibhethri le-0V; isikhathi sokulibaziseka esisethwe ngaphakathi; ukutholwa kwe-voltage enembile kakhulu.

3.2 Ugesi ophansi othule: Ugesi ojwayelekile osebenzayo: 2.8uA; Ugesi olindile: 1.5uA; I-RoHS kanye nokuhambisana okungenalo i-lead.

5. Isimiso Sokusebenza

 

Ukuvikelwa kwebhethri le-lithium le-single-cell ye-Slkor DW03. I-DW03 ifaka i-MOSFET enamandla athuthukisiwe, amasekethe okuthola i-voltage anembile kakhulu, kanye namasekethe okulibazisa, futhi isetshenziswa kabanzi ezintweni ezincane zasekhaya. Kusekethe yohlelo lokusebenza lwe-shaver eboniswe esithombeni, i-USB Type-C inikeza amandla okushaja ibhethri le-lithium le-single-cell. Ngesikhathi sokushaja, i-port ye-ADC I/O ye-MCU iqoqa i-voltage yokushaja futhi ibonise izinga lebhethri kushubhu yedijithali. Isekethe yokushaja yakhiwe ngokuphathwa kokushaja kwe-Slkor SL4056 kanye namasekethe alula angaphandle. Engxenyeni yokushayela kwemoto, kusetshenziswa i-Slkor 3400 MOSFET, kanti i-port ye-MCU I/O iqoqa izimpawu zokhiye ukulawula ukuvula/ukuvala kwemoto. I-DRV iyisignali yokushayela yesango. Lapho i-MCU ithola ukuthi ukhiye ucindezelwe, i-DRV ikhipha izinga eliphezulu bese i-shaver iqala ukujikeleza.

 

5.1 Umfanekiso 1 umane uyisekethe yokubhekisela ye-MCU ukuqoqa ukushaja kwebhethri le-lithium. Qaphela ukuthi i-DW03 ixhuma esigungwini esihle sebhethri le-lithium nge-resistor engu-100R, iphini 2 ye-chip ixhuma esigungwini esibi sebhethri le-lithium, kanye namaphini 4 no-5 axhuma ku-GND. Abasebenzisi bangalandela imininingwane yokuklama nokwakha kalula isekethe yokuvikela ibhethri le-lithium-ion elilodwa elihambisanayo.

 

I-DW03 ivikela ibhethri le-lithium elishajwayo elineseli elilodwa ekulimaleni ngenxa ye-voltage yokushaja ngokweqile, i-voltage yokushaja ngokweqile, i-current yokushaja ngokweqile, i-current yokushaja ngokweqile, kanye ne-short circuit. Uma kungekho zimo ezingavamile ezitholakalayo, i-transistor yokukhipha ihlala ivuliwe, futhi ukushaja nokukhipha kungashintsha ngokukhululeka. Lokhu kubizwa ngokuthi imodi yokusebenza evamile. Ngesikhathi sokukhipha okuvamile, lapho i-voltage yebhethri yehla ngaphansi kwe-voltage yokubona ukushaja ngokweqile (VDL) futhi ubude bufinyelela noma budlula isikhathi sokulibaziseka kokutholakala kwe-voltage yokushaja ngokweqile (TDL), i-DW03 inqamula ibhethri emthwalweni bese iyeka ukukhipha.

 

Lokhu kubizwa ngokuthi isimo se-voltage yokukhipha ngokweqile. Kumodi yokusebenza evamile, lapho i-discharge current ilingana noma iphakeme kunenani elibekiwe (i-voltage ye-VM ilingana noma iphakeme kune-voltage yokuthola i-overcurrent) futhi ubude bufika esikhathini sokulibaziseka kokuthola i-over-discharge current, i-DW03 ivala i-discharge FET bese iyeka ukukhipha. Lokhu kubizwa ngokuthi isimo se-over-discharge current. Ngesikhathi sokushaja okuvamile, uma i-VM voltage yehla ngaphansi kwe-voltage yokutholwa kweshaja (VCHA) futhi ubude budlula isikhathi sokulibaziseka kokutholwa kwe-overcharge current (TCU), i-DW03 ivala i-charge FET bese iyeka ukushaja. Lokhu kubizwa ngokuthi i-normal charge current detection, njll.

 

5.2 KuMfanekiso 2, ama-TVS aqondiswe kabili okuvikela ukukhuphuka yi-Slkor SMF5.0CA, ene-voltage ye-VRWM engu-5.0V kanye nekhono elihle kakhulu lokubopha, enekhono lamandla okushaya okuphezulu elingu-200W ngaphansi kwe-waveform engu-10/1000 µs. I-Q2 kanye ne-Q4 womabili angama-Slkor MOSFET. I-MCU ivumela izilawuli zesiginali i-Q2 ukuthi ivule i-Q4, futhi ngemva kokuthi i-Q4 iqhubekile, i-Type-C ikhipha i-voltage i-VCC ukuze inike amandla umthwalo.

 

5.3 KuMfanekiso 3, i-D4 ne-D5 zisebenza kakhulu njengebhethri kanye nesekethe yokushintsha amandla yohlobo lwe-C. Uma ishaja isusiwe, ibhethri le-lithium linikeza amandla. I-D4 ne-D5 ziyi-Slkor 1N5819WT Schottky diodes, enomugqa wokuvuza obuyela emuva we-1uA, isilinganiso se-voltage esingu-40V, umugqa wokuya phambili ophezulu we-1A, kanye nokwehla kwe-voltage ephansi phambili, okwenza zifaneleke kakhulu ezinhlelweni zokusebenza zamandla aphansi njenge-MCUs.

 

6. Ulwazi lwethebula le-BOM lokuvikelwa kwebhethri le-Slkor DW03 Lithium lulandelayo:

 

I-Slkor Semiconductor inikeza amakhasimende nabasabalalisi ukufinyelela okulula emikhiqizweni emisha ngaphansi kophawu lwe-"Slkor", iqinisa izinsizakalo zokusekela ubuchwepheshe kumakhasimende, futhi inikeza ulwazi oluningiliziwe lomkhiqizo.
