Maxim MAX22088家庭总线收发器解决方案
Maxim公司的MAX22088是和家庭总线标准兼容的家庭总线收发器,数据和电源在一对线路传输,从而最少化外接元件.MAX22088不需要通常总线电源应用所需要的外接AC阻断电感,改善了信号质量,允许使用更长的电缆.此外,器件还集成了5V线性稳压器,给系统负载提供高达70mA电流(最大).器件的其它特性包括可调整接收器滞后,接收器阈值和驱动器转换速率,使得MAX22088适用于各种不同的系统.数据速率从9600bps 到 ≥200kbps.器件集成的保护特性(IEC 61000-4-2 ±8kV接触和±15kV空气隙ESD)保证了苛刻工业环境中通信,工作温度为-40℃ 到 +105℃,紧凑的24引脚4mm x 4mm TQFN封装.主要用在HVAC,电力数据应用,数字标牌以及遥控和检测. 中电网为您整理如下详细资料，本文介绍了MAX22088主要优势和特性,功能框图和简化家庭总线系统,多种应用电路以及评估板MAX22088 EVK主要特性,框图,电路图,材料清单和PCB设计图.
The MAX22088 Homebus transceiver complies with the Homebus standard, where data and power are passed on one single pair of wires, while minimizing the need for external components. The MAX22088 eliminates the large external AC-blocking inductor typically required in bus powered applications and improves the signal quality to allow for longer cables. Additionally, the MAX22088 features an integrated 5V linear regulator to power system loads up to 70mA (max).
The MAX22088 supports passing power and data with speed up to, and exceeding, 200kbps. The MAX22088 features dynamic cable termination to improve the signal quality for applications with high data rates.
