MAX20340 Bidirectional DC PLC Management IC Analog Devices Inc. MAX20340 Bidirectional DC PLC Management IC is ideal for audio applications, game controllers, and handheld radios. The power line communication (PLC) management IC has a 166.7kbps maximum bit rate and is capable of a maximum 1.2A charge current. 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 allows the system to remain in a low-power state until a slave device is connected.
