1A lithium battery charger TP4056 for Mobile phones, PDAs, MP3/MP4

TP4056

brand: tpower semiconductor

1A lithium battery charger

summary

TP4056 is a single cell lithium-ion battery constant current/constant voltage linear charger that utilizes

The SOP8 package with heat dissipation fins at the bottom and simple external application circuits are very

Suitable for portable device applications, suitable for USB power supply and adapter power supply operation, internal

The device adopts an anti reverse charging circuit and does not require an external isolation diode.  Thermal feedback can be beneficial for

Automatic adjustment of charging current for high-power operation or high ambient temperature

Limit the chip temperature under certain conditions.

TP4056 charging cutoff voltage is 4.2V, and charging current can enter through external resistance

Line settings.  When the charging current drops to 1/10 of the set value, TP4056 will automatically

End the charging process.

When the input voltage is removed, TP4056 automatically enters ultra-low power standby mode

State, reduce the standby current to below 1uA.  TP4056 with input power

It can also be placed in shutdown mode to reduce the working current to 40uA.
