Single/Dual isoSPI Transceiver

GENERAL DESCRIPTION The ADBMS68211 (single) and ADBMS68221 (dual) provide bidirectional isolated serial port interface (isoSPI™) communications between two isolated devices through a single twisted pair connection for each data link. Each transceiver encodes logic states into signals that are

单通道/双通道isoSPI收发器

ADBMS6821 （单通道）和ADBMS6822（双通道）通过每个数据链路的单双绞线连接在两个隔离器件之间提供双向隔离串行端口接口(isoSPI™)通信。每个收发器将逻辑状态编码为信号，通过隔离栅传输至另一个收发器。接收器件对传输信号进行解码，并将从机总线驱动至相应的逻辑状态。隔离栅可通过电容或脉冲变压器桥接以实现数百伏隔离。\n\n ADBMS6821/ADBMS6822收发器使用匹配的拉电流和灌电流驱动差分信号，无需变压器中心抽头并降低了电磁干扰(EMI)。接收器中的精密窗口比较器可检测差分信号。\n\n 收发器可与先进的ADI电池堆监控器配对使用，在系统控制器断电时 • 高达 2 Mbps 的隔离式双向串行数据通信\n\n• 放入兼容：单 (ADBMS6821) 和双 (ADBMS6822)\n\n• 完全独立的双收发器 (ADBMS6822)\n\n• 使用电容器或变压器的简单电气隔离\n\n• 单对双绞线上的双向接口\n\n• 支持最长 100 米的电缆长度\n\n• 很低 EMI 易感性和辐射\n\n• ADI 公司电池监视器具有 LPCM 支持\n\n• 中断输出，唤醒 LPCM 系统;
