40-V, 3.5-A H-bridge motor driver with integrated current sensing & current sense feedback

DRV887x 器件系列是靈活的電機(jī)驅(qū)動(dòng)器，適用于各種終端 方案。這些器件集成了 N 溝道 H 橋、電荷泵穩(wěn)壓器、電流檢測(cè)和調(diào)節(jié)、電流比例輸出以及保護(hù)電路。通過支持高側(cè)和低側(cè) N 溝道 MOSFET 和 100% 占空比支持，電荷泵可提升效率。該器件系列具有引腳對(duì)引腳、可擴(kuò)展 RDS(on) 選項(xiàng)，只需對(duì)設(shè)計(jì)進(jìn)行極小改動(dòng)即可支持不同負(fù)載。\n\n在啟動(dòng)期間和高負(fù)載事件中，集成電流檢測(cè)可實(shí)現(xiàn)通過驅(qū)動(dòng)器調(diào)節(jié)電機(jī)電流。利用可調(diào)外部電壓基準(zhǔn)，可設(shè)置電流限制。此外，這些器件還提供與電機(jī)負(fù)載電流成正比的輸出電流。這種特性可用于檢測(cè)負(fù)載條件下的電機(jī)堵轉(zhuǎn)或變化。集成電流檢測(cè)采用內(nèi)部電流鏡架構(gòu)，無(wú)需大功 ?
