MM3659
充(chong)(chong)電(dian)(dian)(dian)(dian)控制(zhi)(zhi)(zhi)IC MM3659兼容USB OTG，4.5A開關(guan)模式，內(nei)置電(dian)(dian)(dian)(dian)源路徑。 同步整流開關(guan)方式的充(chong)(chong)電(dian)(dian)(dian)(dian)控制(zhi)(zhi)(zhi)發熱低，系統供電(dian)(dian)(dian)(dian)和(he)(he)充(chong)(chong)電(dian)(dian)(dian)(dian)控制(zhi)(zhi)(zhi)的效率高。集成 元件，不需要(yao)昂貴的電(dian)(dian)(dian)(dian)流采樣電(dian)(dian)(dian)(dian)阻、功率MOSFET和(he)(he)反向電(dian)(dian)(dian)(dian)流保護二(er)極管(guan)，減少(shao)了元件數量。 單IC實現電(dian)(dian)(dian)(dian)源管(guan)理(li)、系統供電(dian)(dian)(dian)(dian)和(he)(he)充(chong)(chong)電(dian)(dian)(dian)(dian)控制(zhi)(zhi)(zhi)，可減少(shao)設計工時。
