XT9502 Datasheet | Silinktek

Linear Li-Ion Battery Charger - General Description XT9502 series is a double lithium battery charge management chip. The chip includes a charge state detection, the charging process,temperature detection and so on . The chip also integrates a high-precision reference voltage module in it. It uses the SOP-8 package. XT9502 charge contains three modes: precharge,constant current charging,constant voltage charging.Constant current charging current is five times the pre-charge current; when the voltage is lower than 6.5V into the precharge mode; when the voltage is above 6.5V into the conatant current charge mode, the charging current is five times as the precharge, the charging...
