ADBMS6821

單通道/雙通道isoSPI收發(fā)器; ? 高達 2 Mbps 的隔離式雙向串行數(shù)據(jù)通信\n\n? 放入兼容：單 (ADBMS6821) 和雙 (ADBMS6822)\n\n? 完全獨立的雙收發(fā)器 (ADBMS6822)\n\n? 使用電容器或變壓器的簡單電氣隔離\n\n? 單對雙絞線上的雙向接口\n\n? 支持最長 100 米的電纜長度\n\n? 很低 EMI 易感性和輻射\n\n? ADI 公司電池監(jiān)視器具有 LPCM 支持\n\n? 中斷輸出，喚醒 LPCM 系統(tǒng);

ADBMS6821（單通道）和 ADBMS6822?（雙通道）通過每個數(shù)據(jù)鏈路的單雙絞線連接在兩個隔離器件之間提供雙向隔離串行端口接口(isoSPI?)通信。每個收發(fā)器將邏輯狀態(tài)編碼為信號，通過隔離柵傳輸至另一個收發(fā)器。接收器件對傳輸信號進行解碼，并將從機總線驅(qū)動至相應(yīng)的邏輯狀態(tài)。隔離柵可通過電容或脈沖變壓器橋接以實現(xiàn)數(shù)百伏隔離。\n\n ADBMS6821/ADBMS6822收發(fā)器使用匹配的拉電流和灌電流驅(qū)動差分信號，無需變壓器中心抽頭并降低了電磁干擾(EMI)。接收器中的精密窗口比較器可檢測差分信號。\n\n 收發(fā)器可與先進的ADI電池堆監(jiān)控器配對使用，在系統(tǒng)控制器斷電時也能實現(xiàn)電池單元電壓和傳感器監(jiān)控（低功耗電池單元監(jiān)控或LPCM）。收發(fā)器提供超時功能，在編程的時間周期內(nèi)未接收到傳遞心跳消息時，該功能可喚醒或提醒系統(tǒng)。\n\n 在整個數(shù)據(jù)手冊中，所有引腳名稱均指ADBMS6822上的兩個收發(fā)器。例如，VDD指VDD和VDD2。\n\n
