EXT950286M1XR Datasheet | E-CMOS

Description EXT9502 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. EXT9502 charge contains three modes: pre-charge, 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 pre-charge mode; when the voltage is above 6.5V into the conatant current charge mode, the charging current is five times as the pre-charge, the charging current is dertermined by an external resistor. Features - Double lithium battery charge management - Only need a few external penents - Pre-charge, constant current charging, constant voltage charging mode - Temperature detection - Two charging status - SOP8 Package Applications - Digital camera - PDAS - The phone lithium battery Ordering/Marking information EXT9502 XX XX X R Tape & Reel Voltage Accuracy： A：±1% B：±2% Voltage ： 78=7.8V 80=8.0V 82=8.2V 84=8.4V 86=8.6V 88=8.8V Package： M1：SOP8 Part number Package Marking EXT9502XXM1R SOP8 E-CMOS Corp.
