The MAX20357 is a Power Line Communication (PLC) slave with ModelGauge m5 EZ fuel gauge and charger. The MAX20357 and MAX20355 provide a complete system solution for charging and data transfer between a charging case and battery powered device over a single contact.
The PLC interface is capable of 100kpbs throughput while simultaneously providing 200mA of charging/system current per channel. A 4Mbaud halfduplex data only UART mode provides an easy and fast method for firmware updates, debugging interface, and factory modes.
The charger on slave device MAX20357 controls the output of the 3.3W buck-boost converter in the MAX20355 with dynamic voltage scaling (DVS).
The MAX20357 integrates an ultra-low power fuelgauge which implements the Maxim ModelGauge™ m5 algorithm. The IC monitors a single-cell battery pack and supports internal current sensing.
Additional features include comprehensive master device insertion and removal notifications, moisture detection, overcurrent protection, and 8kV contact rated ESD protection on the PLC output.
