MAX20340
General Description
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).
