Yakaunza mashandisirwo uye musimboti wekushanda weR5426 chip mune microcontroller

Mazuva ano, zvigadzirwa zvemagetsi zvinotakurika zviri kuramba zvichinyanya kufarirwa, uye midziyo yavo yebhatiri yave kutarisisa. Lithium mabhatiri uye polymer lithium mabhatiri zvishoma nezvishoma akatsiva nickel-cadmium mabhatiri uye nickel-hydrogen mabhatiri sechisarudzo chekutanga chemidziyo inotakurika nekuda kwekuwanda kwesimba rayo, nguva yekushandisa kwenguva refu, uye yakakwirira yekuchengetedzwa kwezvakatipoteredza zvinodiwa. Ricoh’s lithium-ion kugadzirisa chip R5426 yakatevedzana yakanyatso kugadzirirwa michina inotakurika senge nharembozha, pdas, uye monolithic lithium mabhatiri.

R5426 yakatevedzana ndeye overcharge / discharge / overcurrent kugadzirisa chip, iyo inogona kubhadhariswa ne lithium ion / bhatiri.

R5426 akateedzana anogadzirwa neakakwira voltage tekinoroji, anomira nevoltage isiri pasi pe28V, akaiswa mu6-PIN, SOT23-6 kana SON-6, ine yakaderera simba rekushandisa (yakajairika simba ikozvino kukosha kwe3.0UA, yakajairika standby ikozvino kukosha kwe0.1UA. ), high precision Detection threshold, zvakasiyana-siyana zvekugadzirisa zvikumbaridzo, yakavakirwa-mukati yakabuda inononoka kuchaja uye 0V yekuchaja mabasa, kuchengetedza kwekushanda mushure mekusimbiswa.

Imwe neimwe yedunhu yakabatanidzwa ine ina ma detectors emagetsi, referensi redunhu unit, inononoka dunhu, pfupi-dunhu muchengeti, oscillator, counter uye logic circuit. Kana iyo yekuchaja voltage uye yekuchaja yazvino ichiwedzera kubva kudiki kusvika kuhombe uye ichipfuura inoenderana chikumbaridzo detector (VD1, VD4), pini inobuda Cout inowaniswa neinobuda voltage detector / VD1 kuchengetedza, uye yakawandisa uye yakawandisa detector / VD4 inopfuura inopindirana Kunonoka kwemukati kunoshandura kusvika kune yakaderera. Mushure mekunge bhatiri yawandisa kana kuwandisa, bvisa bhatiri paki kubva pajaja uye batanidza mutoro kuVDD. Kana iyo bhatiri voltage inodonha pazasi kukosha kwechaji, iwo maviri anoenderana madhijitari (VD1 neVD4) anogadzwa patsva, uye kubuda kweCout kunokwira. Kana bhatiri pack richiri mujaja, kunyangwe bhatiri remagetsi rakaderera pane overcharge test value, overcharge kugadzirisa hakugone kuregererwa.

DOUT pini ndiyo pini inobuda yedhinari yekuwandisa (VD2) uye overdischarge detector (VD3). Kana iyo yekuburitsa voltage yakaderera pane chikumbaridzo voltage VDET2 ye overdischarge detector kubva kumusoro kusvika pasi, kureva, yakaderera pane VDET2, pini yeDOUT inodonha kusvika yakaderera mushure mekunonoka kwakagadziriswa kwemukati.

Mushure mekuona kudarika-kubuda, kana charger yakabatana nebhatiri pack, kana bhatiri rekupa simba rakakwirira kudarika chikumbaridzo voltage ye-over-discharge voltage detector, VD2 inosunungurwa uye DOUT inova yakakwirira.

Yakavakwa-inopfuura-ikozvino / pfupi-circuit detector VD3, mushure mekugadzirisa kwakagadziriswa kunonoka, nekushandura kubudiswa kweDOUT kusvika kune yakaderera, kubudiswa kwepamusoro-ikozvino kunonzwa uye kubudiswa kunogurwa. Kana kana nguva pfupi-yekutenderera ikozvino yakaonekwa, kukosha kweDOUT kunoderedzwa pakarepo, uye kubuda kunogurwa. Kana imwe nguva iyo yakanyanyisa kana kuti pfupi yedunhu yaonekwa, bhatiri paki inoparadzaniswa kubva pamutoro, VD3 inosunungurwa, uye chiyero cheDOUT chinowedzera.

Mukuwedzera, mushure mekuona kubuda, chip ichamisa kushanda kwemukati wekati kuitira kuchengetedza simba rekushandisa rakaderera zvikuru. Nekuisa iyo DS terminal kusvika padanho rakafanana neiyo VDD terminal, kunonoka kwekugadzirisa kunogona kupfupikiswa (kunze kwekupfupika-chekugadziridza). Kunyanya, kunonoka kwekugadzirisa kwepamusoro kunogona kuderedzwa kusvika 1/90, iyo inoderedza nguva inodiwa yekuedza nekuchengetedza dunhu. Kana iyo DS terminal level ikaiswa mukati meimwe nhanho, kunonoka kwekubuda kunodzimwa, uye overcharge uye overcharge ikozvino zvinoonekwa nekukurumidza. Panguva ino, kunonoka kunenge makumi emamicroseconds.
