The MAX20355A is a power line communication (PLC) controller with a ModelGauge™ m5 EZ fuel gauge and buck-boost converter. With the MAX20357A, the MAX20355A provides a complete system solution for charging and data transfer between a charging case and a battery-powered device over a single contact.
The PLC interface is capable of 100kpbs throughput while simultaneously providing 400mA of total charging/system current. A 4Mbaud half-duplex dataonly UART mode provides an easy and fast method for firmware updates, debugging interface, and factory modes.
The MAX20355A controller device utilizes a 3.3W buckboost converter with dynamic voltage scaling (DVS) to automatically manage the charging voltage based on the slave device MAX20357A control signal.
Additional features include comprehensive slave device insertion and removal notifications, moisture detection, overcurrent protection, and 8kV contact-rated ESD protection on the PLC outputs.
