1.Explanation

TP4057-42 is suitable for single-cell lithium battery charger, with battery positive and negative pole reverse connection protection, using constant current/constant voltage linear control. TP4057-42 is suitable for USB power supply and adapter power supply work. TP4057-42 adopts internal PMOSFET architecture, plus anti-reverse charging circuit, does not require external detection resistor and isolation diode. Thermal feedback can automatically adjust the charging current. The charging current can be set externally via a resistor. When reaching 4.2V, the charging current drops to 1/10 of the set value, TP4057-42 will automatically terminate the charging

2.Detailed introduction of TP4057-42
TP4057-42 is suitable for single-cell lithium battery charger, with battery positive and negative pole reverse connection protection, using constant current/constant voltage linear control. TP4057-42 is suitable for USB power supply and adapter power supply work.
TP4057-42 adopts internal PMOSFET architecture, plus anti-reverse charging circuit, does not require external detection resistor and isolation diode. Thermal feedback can automatically adjust the charging current. The charging current can be set externally via a resistor. When the battery reaches 4.2V, the charging current drops to 1/10 of the set value, and the TP4057-42 will automatically terminate charging.
When the input voltage (AC adapter or USB power supply) is removed, the TP4057-42 automatically enters a low current state, and the battery leakage current is below 2uA. Other features of the TP4057 include charging current monitoring, undervoltage lockout, automatic recharge, and two status pins for indicating the end of charging and input voltage access
