EXT9502-Linear Li-Ion Battery Charger

General Description

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.
