Working Principles

The ISL6292-1CR5-T operates by regulating the charging current and voltage to the connected battery. It uses a constant current mode initially to rapidly charge the battery until it reaches a predefined voltage threshold. At this point, it switches to constant voltage mode to maintain the battery voltage at the desired level while reducing the charging current. The IC continuously monitors the battery temperature and adjusts the charging parameters accordingly to prevent overheating or overcharging.
