增強(qiáng)型、快速、低功耗、四通道、3.75kVRMS數(shù)字隔離器

MAX22344–MAX22346為增強(qiáng)型、快速、低功耗、4通道數(shù)字隔離器，采用Maxim專有的工藝技術(shù)。這些器件在不同電源域的電路之間傳輸數(shù)字信號(hào)，在1Mbps數(shù)據(jù)率(1.8V電源電)下的功耗只有0.74mW每通道。該家族中的所有器件具有增強(qiáng)的隔離性能，可承受額定3.75kVRMS隔離電壓（長(zhǎng)達(dá)60秒）。 \n\n MAX22344–MAX22346家族提供所有可能的單向通道配置，支持任何形式的4通道設(shè)計(jì)，包括SPI、RS-485和數(shù)字I/O應(yīng)用。MAX22345R/S的A側(cè)輸出使能為低電平有效，由于CS信號(hào)可直接使能隔離器上的MISO信號(hào)，使其成為在共用SPI總線上進(jìn)行端口隔離的 ? 支持快速數(shù)字信號(hào)的增強(qiáng)電隔離\n? 數(shù)據(jù)率高達(dá)200Mbps\n? 可承受3.75kVRMS達(dá)60s (VISO)\n? 連續(xù)承受784VRMS (VIOWM)\n? GNDA和GNDB之間可承受±10kV浪涌，1.2/50μs波形\n? 高CMTI (50kV/μs，典型值)\n\n\n? 低功耗\n? 0.74mW/通道 @ 1Mbps，VDD = 1.8V\n? 1.4mW/通道 @ 1Mbps，VDD = 3.3V\n? 3.2mW/通道 @ 100Mbps，VDD = 1.8V\n\n\n? 多種選項(xiàng)，支持較寬應(yīng)用范圍\n? 2種最大數(shù)據(jù)率(200Mbps、25Mbps)\n? ;
