General Description<\/h3>\n\n\n\n

EXT9502 series is a double lithium battery charge management chip.
The chip includes state detection, the charging process, temperature detection and so on.
also integrates high-precision reference voltage module in it.
It uses SOP-8 package.
contains three modes: pre-charge, constant current charging, charging.
Constant five times current; when lower than 6.5V into mode; above conatant mode, as dertermined by an external resistor.<\/p>\n\n\n\n
