TP4056 1A Li-ion Lithium Battery Charging Module with Current Protection – Mini USB

DESCRIPTION

The TP4056 1A Li-ion Lithium Battery Charging Module with Current Protection - Mini USB is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. Its SOP package and low external component count make the TP4056 ideally suited for portable applications. The TP4056 can work with USB and wall adapter.

The Li-ion Cell Charger/Monitor module used for this Battery pack solution is based on TP4056 1A Standalone Linear Li-lon Battery Charger with Thermal Regulation chip. No blocking diode is required due to the internal PMOSFET architecture and have prevent to negative Charge Current Circuit. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The TP4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.

TP4056 Other features include current monitor, under voltage lockout, automatic recharge and two status pin to indicate charge termination and the presence of an input voltage.

Using the module:

• Connect mini USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
• Connect cell to charge to B+/B- pads on the right-hand side of the module.
• A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
• Important! Disconnect load when charging
• The red LED indicates charging in progress, green LED indicates charging has finished.
• Never charge your battery at a rate greater than 1C.

Features :

• Led indicator: red is charging Green is fully charged.
• Current Protection: Yes
• Inversed polarity: NO.
• Use mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy.
• Fully machinery automated processing, all patch parts manufacturing.

Specifications:

Note:

• Ampere meter can only be connected to a 5v input end of the module.
• It is better than the charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, a current of 400mAh is enough.
• The connection wire should not be too thick.
• Make sure the connect point is good.
• If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to the chip.
• NO Reverse polarity.

Package Includes :

• 1 x TP4056 1A Li-ion lithium Battery Charging Module with Current Protection – Mini USB
