A4057规格书详情
DESCRIPTION
A4057 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.
A4057 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 constant current charge mode, the charging current is five times as the precharge, the charging current is determined by an external resistor.
