8.4v dual lithium battery professional charging IC (fs4062a)

5v Boost charging IC; Boost charging management chip FS4062A;8.4v Boost charging IC;5v Boost charging 8.4v chip USB Boost charging double section lithium battery management ;

FS4062A Is a usable 5V Integrated management circuit for power supply and boost charging of multiple series lithium batteries .FS4062A It is very suitable for multi string lithium battery or lithium iron phosphate battery
Charge management , External location NMOS And selecting different power according to the charging current MOS, Less peripheral components and simple application . 
FS4062A With trickle 、 constant current 、 Constant voltage charging mode , Very suitable for lithium battery or lithium iron phosphate battery
Charging of . The constant voltage charging value is set by the external voltage dividing resistor network , The constant current charging value passes the external current detection
Resistance value setting . For deeply discharged batteries , Use the setting when the battery voltage is lower than the trickle charging threshold
Constant current charging 15% Trickle charge the battery . In the constant voltage charging stage , The charging current gradually decreases ,
When the charging current decreases to the value of constant current charging 10% It is determined that the battery is fully charged .
