Itprovides 1% regulation accuracy over the specified temperaturerange without requiring the use of external precisionresistors. The IC controls five charge modes: conditioning,fast, top-off, monitor and maintenance. In addition, theLM3621 detects and flags defective batteries as well as overcurrent and over voltage fault events. The architecture of theIC is based on high gain constant voltage and constantcurrent control loops.
