800mA BTL線性控制風(fēng)扇馬達驅(qū)動芯片

EUM6883是一款用于單相無刷直流馬達的驅(qū)動芯片。作為HALL IC和單相直流無刷馬達的接口，它通過BTL線性控制輸出對馬達進行驅(qū)動，具有低導(dǎo)通壓降、低噪聲、高效率的特點。EUM6883內(nèi)置線性控制模式、風(fēng)扇轉(zhuǎn)速輸出、鎖定保護、自動重啟以及熱關(guān)斷等功能，并能為Hall IC提供偏置。當輸出電壓由低到高或由高到低變化時，線性控制模式會根據(jù)轉(zhuǎn)速快慢調(diào)整其變化斜率，使馬達能應(yīng)用在對靜音和可靠性要求較高的電子設(shè)備中。如果馬達在運轉(zhuǎn)過程中被卡住，過驅(qū)動電流會引起溫度升高而損壞馬達。為防止此現(xiàn)象，馬達卡住時EUM6883會切斷驅(qū)動電流，幾秒鐘后再嘗試恢復(fù)驅(qū)動。風(fēng)扇轉(zhuǎn)動時RD為低電平，停轉(zhuǎn)時為高電平。FG ? 線性控制，單相全波驅(qū)動\n? 寬應(yīng)用電壓1.8V～13.8V\n? 低導(dǎo)通壓降（0.5V @ 250mA）\n?
