MM3474 series adopts high voltage CMOS process, for 2 times with lithium
batteries/polymer battery overcharge, overdischarge and overcurrent can protect
the IC. When a section 3 ~ 5 day of lithium batteries/polymer battery happened
in charge, over discharge and over current can have some protection. In
addition, the cascade MM3474, corresponding 6 section above the application of
the battery. IC by internal voltage detector, the reference voltage source, OR
circuit, no induction time setting circuit, logic circuit, etc.
