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.
◆Double lithium battery charge management
◆Only need a few external compenents
◆Pre-charge, constant current charging, constant voltage charging mode
◆Two charging status
◆The phone lithium battery >”)}
