The TP4056 is designed as one kind of single lithium-ion battery which uses the constant current/constant voltage linear charger. The SOP8/MSOP8 package with the radiator in the bottom and less external components number make the TP4056 become the ideal choice of the portable applications. The TP4056 is suitable for the operating of the USB power and the adapter power. Because this device uses the internal PMOSFET architecture and the anti-reverse-charging circuit, so there is no need to use the external isolation diode. The heat feedback can automaticly adjust the charging current to limit the chip temperature in the high power operation or high environment temperature conditions.
