Bidirectional DC Powerline Communication Management IC

World's Smallest DC Powerline Communication Solution

Please check latest availability status for a specific part variant.


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).
