TP4056 1A 5V Li-ion lithium Battery Charging Module – Mini USB

The TP4056 1A Li-Ion Lithium Battery Charging Module – Mini B USB is a 3.7V lithium battery charger module that has an onboard Mini USB interface. With a Mini-USB onboard connector, you can directly connect to a computer USB port for battery charging. If USB is not available you can use an external source voltage at IN+/IN- pads, great for DIY projects. It is small in size and lightweight.

Manufactured under full machinery processing. Each module is tested OK before shipment from KitsGuru.com so it has high reliability for the best performance. In conclusion, it is a special design for a single lithium battery charging.

It uses the internal PMOSFET architecture which eliminates the use of a blocking diode. It prevents 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 charging current is programmable 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 the current monitor, under voltage lockout, automatic recharge, and two status pins to indicate charge termination and the presence of an input voltage.

Note1 : HW-167 on module working remains the same.

Note2 :This breakout board does not have Overcurrent protection.

Connect the Ampere meter in series with a 5V input end.

The charging current is best to be 0.37 times the battery capacity, Charging wire can’t be too thin or too long while interfacing.

Make sure the board has good contact with the battery.

Chip is at work at about 60 degrees fever is normal.

Input reverse connection has no effect on the chip. Rather the output (battery’s) reverse connection will burn out the chip.
