High CMRR RS-485 Transceiver with ?50V Isolation

General Description The MAX3157 is a high CMRR RS-485/RS-422 data-communications interface providing ±50V isolation in a hybrid microcircuit. A single +5V supply on the logic side powers both sides of the interface, with external ±50V capacitors transferring power from the logic side to the isola

高共模抑制比RS-485收發(fā)器，帶有±50V隔離

MAX3157是一款高CMRR RS-485/RS-422數(shù)據(jù)通信接口，在混合微電路中可提供±50V隔離。邏輯端的+5V單電源為接口的兩側(cè)供電，外部±50V電容由邏輯端向隔離端傳輸電源。每個MAX3157包含一個發(fā)射器和一個接收器，并保證以高達250kbps的數(shù)據(jù)速率運行。驅(qū)動器具有短路限流功能，并且通過熱關(guān)斷電路將驅(qū)動器輸出置于高阻抗狀態(tài)，以防止功耗過大。接收器輸入具有故障安全功能，如果輸入開路、短路或連接到端接傳輸線并禁用所有驅(qū)動器，該功能可確保接收器輸出為邏輯高電平。\n\n MAX3157在空載時或滿載且禁用驅(qū)動器時的典型電源電流消耗為25mA。當器件處于關(guān)斷模式時，電源電流 ? ±50V隔離式數(shù)據(jù)接口\n? +5V單電源\n? 光隔離收發(fā)器的低成本替代器件\n? 真正的故障安全接收器，同時保持EIA/TIA-485合規(guī)性\n? 引腳可選的全/半雙工操作\n? 通過相位控制進行雙絞線反轉(zhuǎn)校正\n? 低功耗關(guān)斷模式：25μA\n? 提供熱關(guān)斷功能，以實現(xiàn)驅(qū)動器過載保護\n? 28引腳SSOP封裝\n? 提供擺率限制以降低EMI;
