STDRIVE101是適用于驅(qū)動(dòng)三相無(wú)刷電機(jī)的低壓柵極驅(qū)動(dòng)器。\n\n 它是一種帶有三重半橋柵極驅(qū)動(dòng)器的單晶片，面向N溝道功率MOSFET。每個(gè)驅(qū)動(dòng)器的電流能力為600 mA（灌/拉）。它集成了一個(gè)低壓降線性穩(wěn)壓器，可通過(guò)自舉電路為低側(cè)和高側(cè)柵極驅(qū)動(dòng)器生成電源電壓。\n\n 該器件在低側(cè)和高側(cè)部分均提供欠壓鎖定（UVLO），可防止電源開關(guān)在低效率或危險(xiǎn)條件下工作。\n\n 集成在STDRIVE101中的控制邏輯允許兩種輸入策略（高側(cè)和低側(cè)或啟用和PWM驅(qū)動(dòng)信號(hào)）。根據(jù)DT/MODE引腳選擇驅(qū)動(dòng)方式。這兩種情況下，互鎖或內(nèi)部產(chǎn)生的死區(qū)時(shí)間可確保防止交叉?zhèn)鲗?dǎo)。\n\n STDRIVE101還具有用 ? 工作電壓：5.5至75 V \n? 600 mA灌/拉電流能力 \n? 3.3 V和5 V控制邏輯 \n? 兩種輸入策略： \n ?帶生成死區(qū)時(shí)間可調(diào)的ENx/INx \n ?帶互鎖的INHx/INLx \n? 面向所有溝道的匹配傳播時(shí)延 \n? 極短的傳輸延時(shí)：40 ns? 集成自舉二極管 \n? 12 V LDO線性穩(wěn)壓器（最大50 mA） \n? 用于每個(gè)外部MOSFET的嵌入式VDS監(jiān)控器 \n? 過(guò)流比較器 \n?
