Maxim公司的MAX20340是通用双向DC动力线通信(PLC)管理集成电路,最大比特速率166.7kbps,自动模式的数据吞吐量为5.7kbps,最大充电电流1.2A.具有灵活配置,单电阻编程,PLC主或从,双或单从模式(主),PLC从寻址(从),I2C寻址,小型解决方案尺寸, 1.358mm x 1.358mm WLP封装,主要是用在真正无线耳塞,有线无线耳机,助听器,可穿戴电子,游戏控制台,手持无线电, 销售点(POS)设备.本文介绍了MAX20340主要特性和优势,功能框图,耳塞充电框图,以及评估板MAX20340 EVK主要特性,电路图,材料清单和PCB设计图.

The MAX20340 is a universal bidirectional DC powerline communication (PLC) management IC with a 166.7kbps maximum bit rate. The device is capable of a maximum of 1.2A charge current. The MAX20340 features a slave detection circuit that flags an interrupt to the system when the PLC master detects the presence of a PLC slave on the powerline. This function allows the system to remain in a low-power state until a slave device is connected. Many of the features of the MAX20340, such as master/slave mode, I2C address, dual/single PLC slave mode, and PLC slave address, are pin configurable.The device is available in a 9-bump, 0.4mm pitch, 1.358mm x 1.358mm wafer-level package (WLP).

MAX20340主要特性和优势:

•Compact, Simple Solution for PLC
•Up to 166.7kbps Bit Rate
-5.7kbps Data Throughput in AutomaticMode
