TP4056 Module Type C

TP4056 Protection Type C

Protected Lithium Lion  Battery Charger Circuit Type C Usb Battery

     The TP4056 Type-C Protected Lithium Battery Charger Module charges a single-cell 3.7V Li-ion (18650 etc.) or LiPo battery with 5V from its USB Type-C input. Charging is done by the TP4056 IC with the constant current / constant voltage (CC/CV) method: the battery charges at 1A, the current falls when the voltage reaches 4.2V and charging ends automatically. The red LED is on while charging and the green LED lights up when charging is complete.

     In this version the charger is accompanied by a DW01A protection IC and an 8205A dual MOSFET. When the load is connected to the OUT+ and OUT- pads, the board protects the battery against over-discharge (about 2.5V), overcurrent (3A) and output short circuit. Power is supplied through the Type-C socket or the + and - pads on the board edge; the battery is soldered to the B+ and B- pads. The board measures about 28mm x 17mm and fits easily inside a device.

     The charge current is set to 1A by the R3 (RPROG) resistor on the board; by changing the resistor the current can be reduced to between about 130mA and 1000mA. This allows safe charging of small capacity LiPo batteries as well. Single-cell (1S) batteries connected in parallel can also be charged.

Key features:

     Type-C input: Powered by a current phone charger and Type-C cable; the battery is charged from a 5V USB source. The + and - pads on the edge can also be used for an external 5V supply.

     Battery protection on board: The DW01A protection IC and 8205A MOSFET protect the battery against over-discharge, current above 3A and short circuit for the current drawn from the OUT+ / OUT- output. It adds protection to an unprotected single cell.

     Accurate charge voltage: Charging is done with the CC/CV method at 4.2V ±1.5% accuracy; the current stops when the battery is full and the green LED lights up.

     Adjustable charge current: The default 1A charge current can be set between about 130mA and 1000mA by changing the R3 resistor; the current is reduced for small batteries.

     Small and easy to solder: The board, about 28mm x 17mm in size, connects easily to the battery and the device thanks to its large solder pads.

Usage information:

• Solder the + terminal of the battery to B+ and the - terminal to the B- pad. Connect the load (device) to the OUT+ and OUT- pads; the protection works only for the current drawn from this output.
• Connect the board to a 5V adapter with a Type-C cable or to a 5V source through the + and - pads. The red LED is on while charging and the green LED lights up when charging is complete.
• To reduce the charge current change the R3 resistor: 1.2kΩ = 1000mA, 1.5kΩ = 780mA, 2kΩ = 580mA, 3kΩ = 400mA, 5kΩ = 250mA, 10kΩ = 130mA. The charge current should not exceed 1C of the battery capacity; reduce the current for batteries below 1000mAh.
• Use good quality wires of sufficient cross-section for the supply and battery; the resistance of thin or poor wires reduces the charge current.
• It is normal for the IC to warm up to 60 degrees during charging.

Areas of use:

•  Powerbank building
•  Flashlight: rechargeable flashlight and headlamp
•  Toy: rechargeable toys
•  Speaker: portable Bluetooth speaker
•  Headphones and small portable devices
•  Lamp: rechargeable desk lamp and LED lamp
•  Robot: battery powered robot and vehicle projects
•  Wireless sensor and measuring devices
•  Adding charging and protection to an unprotected 18650 or LiPo cell

Precautions:

•  Do not connect the battery in reverse. Reverse connection at the B+ and B- pads destroys the TP4056 and DW01A ICs and may damage the battery.
•  The input voltage should be 5V and must not exceed 5.5V. A supply above 5V heats the IC and reduces the charge current.
•  The load should be disconnected while charging. If a load stays connected to the OUT output during charging, charging may not terminate correctly.
•  The board is for a single cell (1S, 3.7V) only. It does not charge packs with 2 or more cells in series (7.4V, 11.1V) or LiFePO4 (3.2V) batteries.
•  The charge current should not exceed 1C of the battery capacity. Charging a small battery at 1A damages it; reduce the current with R3.
