帶轉(zhuǎn)換器的 DMOS 微步驅(qū)動(dòng)器

A3987 是一款完全的微步電動(dòng)機(jī)驅(qū)動(dòng)器，帶有內(nèi)置轉(zhuǎn)換器，易于操作。該產(chǎn)品可在完整、1/2、1/4 及 1/16 步進(jìn)模式時(shí)操作雙極步進(jìn)電動(dòng)機(jī)，輸出驅(qū)動(dòng)容量為 50 伏特及 1.5 安培。A3987 包括一個(gè)固定停機(jī)時(shí)間電流穩(wěn)壓器，該穩(wěn)壓器可在慢或混合衰減模式下工作。\n\n轉(zhuǎn)換器是 A3987 易于實(shí)施的關(guān)鍵。只要在“步進(jìn)”輸入中輸入一個(gè)脈沖，即可驅(qū)動(dòng)電動(dòng)機(jī)產(chǎn)生一個(gè)微步。該程序中沒有相位順序表、高頻率控制行或復(fù)雜的界面。A3987 界面對(duì)于復(fù)雜的微處理器不可用或過載時(shí)的應(yīng)用情況下是理想的器件。\n\nA3987 斬波控制可自動(dòng)選擇電流衰減模式（慢或混合）。當(dāng)出現(xiàn)一個(gè)“步進(jìn)”信號(hào)時(shí)，該轉(zhuǎn)換器會(huì) ? 低 RDS(on) 輸出 \n? 加載短路保護(hù) \n? 混合與慢電流衰減模式 \n? 內(nèi)部欠壓鎖定 (UVLO) 及過熱關(guān)機(jī)電路 \n? 交叉電流保護(hù) \n;
