750 mA、內(nèi)置電流調(diào)整電路、雙極步進(jìn)電機(jī)

HR3967是一種專(zhuān)門(mén)用于雙極步進(jìn)電機(jī)的微步進(jìn)電機(jī)驅(qū)動(dòng)集成電路，能以全、1/2、1/4及1/8微步細(xì)分驅(qū)動(dòng)馬達(dá)，輸出額定值能達(dá)到30V、±750 mA 。電路內(nèi)置的固定衰減時(shí)間電流調(diào)整電路，使得馬達(dá)能夠在快、慢或混合衰減模式下工作，大大減小了馬達(dá)轉(zhuǎn)動(dòng)時(shí)的噪聲，增加了馬達(dá)的步進(jìn)精度，同時(shí)降低了電路的功耗。\r\n\r\n 內(nèi)置轉(zhuǎn)換器TRANSLATOR是電路工作的關(guān)鍵，它使得簡(jiǎn)單的施加一個(gè)脈沖給STEP就能夠方便的控制馬達(dá)的步進(jìn)；通過(guò)選擇MS1/MS2的電平就能夠使馬達(dá)在全、1/2、1/4、1/16步進(jìn)模式間進(jìn)行切換；它減少了負(fù)載相序表、高頻控制線和外部編程接口；使得電路的外部控制界面 ? ±750 mA, 30 V 額定輸出\r\n? 自動(dòng)電流衰減檢測(cè)\r\n? 3.3V和5V兼容邏輯電平\r\n? 支持混合、快、慢衰減模式\r\n? 內(nèi)置欠壓鎖定、過(guò)熱關(guān)斷等保護(hù)電路\r\n?
