Maxim公司的MAX20340是通用双向DC动力线通信(PLC)管理集成电路,最大比特率为166.7kbps,器件的最大充电电流为1.2A. 器件具有从指向电路,当PLC主检测到在动力线上存在PLC从时能对系统进行中断.这种功能使得系统保持在低功耗状态直到从设备被连接上.MAX20340的许多特性如主/从模式,I2C寻址,双路/单路PLC从模式和PLC从地址是引脚可配置的.器件采用1.358mm x 1.358mm WLP封装.主要用在真正的无线耳塞,有线无线耳机,助听器,可穿戴,游戏控制台,手持无线电和销售终端(POS)设备.本文介绍了MAX20340主要优势和特性,功能框图,带吊架无线耳塞充电路以及评估板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 power line. 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).
