MAX20340 Bidirectional DC Powerline Communication Management IC General Description Benefits and Features The MAX20340 is a universal bidirectional DC powerline Compact, Simple Solution for PLC communication (PLC) management IC with a 166.7kbps Up to 166.7kbps Bit Rate maximum bit rate. The device is capable of a maximum - 5.7kbps Data Throughput in Automatic Mode of 1.2A charge current. 1.2A Charge Current Automatic Detection of PLC Slave Presence The MAX20340 features a slave detection circuit that flags an interrupt to the system when the PLC master Flexible Configuration detects the presence of a PLC slave on the power Single Resistor to Program line. This function allows the system to remain in a low- PLC Master or Slave power state until a slave device is connected. Dual or Single Slave Mode (Master Only) PLC Slave Address (Slave Only) Many of the features of the MAX20340, such as 2 2 I C Address master/slave mode, I C address, dual/single PLC slave mode, and PLC slave address, are pin configurable. Small Solution Size Space-Saving 0.4mm Pitch, 9-Bump, The device is available in a 9-bump, 0.4mm pitch, 1.358mm x 1.358mm WLP 1.358mm x 1.358mm wafer-level package (WLP).
