DRV870xD-Q1器件系列是一種半橋柵極驅(qū)動(dòng)器,它使用兩個(gè)外部N通道MOSFET,旨在驅(qū)動(dòng)單向刷式直流電機(jī)或者是螺線管負(fù)載。
PWM接口允許輕松連接到控制器電路。這款柵測(cè)驅(qū)動(dòng)器內(nèi)置有相應(yīng)的電路,以便能夠采用關(guān)斷時(shí)間固定的PWM電流斬波來(lái)調(diào)節(jié)繞組電流。
DRV870xD-Q1器件系列通過(guò)10.5VV GS 柵極驅(qū)動(dòng)器驅(qū)動(dòng)高側(cè)和低側(cè)FET。所有外部FET的柵極驅(qū)動(dòng)電流都可通過(guò)單一外部電阻器或通過(guò)串行外設(shè)接口(SPI)進(jìn)行配置。
低功耗睡眠模式可將部分內(nèi)部電路關(guān)斷,從而實(shí)現(xiàn)極低的< br>靜態(tài)電流消耗。
<小>所有商標(biāo)是其相應(yīng)所有者的財(cái)產(chǎn)。
