數(shù)據(jù): bq76PL536A 3 至 6 節(jié)串聯(lián)鋰離子電池監(jiān)視器和二級(jí)保護(hù) IC 數(shù)據(jù)表 (Rev. C)
bq76PL536A器件是一款用于3至6節(jié)串聯(lián)鋰離子電池的可堆疊電池監(jiān)視器和保護(hù)器.bq76PL536A集成有模擬前端(AFE與高精度模數(shù)轉(zhuǎn)換器(ADC),共同用于實(shí)現(xiàn)對(duì)電池電芯電壓的精確測(cè)量。溫度使用一個(gè)單獨(dú)的ADC進(jìn)行測(cè)量。
除了測(cè)量溫度外,該器件還能夠?yàn)楦鱾€(gè)通道提供過(guò)壓和欠壓監(jiān)控保護(hù)。該器件通過(guò)非易失性存儲(chǔ)器來(lái)存儲(chǔ)用戶可編程的保護(hù)閾值和延遲時(shí)間。一旦超出其中某個(gè)閾值,就會(huì)輸出故障信號(hào)。
< p>通過(guò)堆疊bq76PL536A器件,可支持由192個(gè)電芯組成的疊層電池。所有器件通過(guò)高速SPI接口進(jìn)行連接。
