Description

1-10PCS TC4056A Lithium Battery Charger Module TYPE C USB 5V 1A Charging Board With Protection Functions PCB For Arduino DIY

The TC4056A is a complete single-cell Li-Ion battery with a constant current/constant voltage linear charger. The SOP40 package with heatsink on the bottom of the TC4056A and fewer external components make the TC4056A ideal for portable applications. The TC4056A is suitable for USB power and adapter power supplies.

Due to the internal PMOSFET architecture and anti-reverse charging path, no external isolation diodes are required.

Thermal feedback automatically adjusts the charge current to limit chip temperature during high power operation or high ambient temperature conditions. The charging voltage is fixed at 4.2V, and the charging current can be externally set by a resistor. When the charging current drops to the set value of 1/10 after reaching the final float voltage, the TC4056A will automatically terminate the charging cycle. When the input voltage (AC adapter or USB power) is removed, the TC4056A automatically enters a low current state, reducing the battery leakage current to less than 2uA. The TC4056A can also be placed in shutdown mode when there is a power supply, reducing the supply current to 55uA.

Other features of the TC4056A include battery temperature sensing, undervoltage lockout, automatic recharge, LED status pins for charging and termination.

Protection About Type-c usb module and micro usb type-1 module :

The battery overcharge protection voltage: 4.28 V

Battery overcharge lifting voltage: 4.00 V

The battery discharge protection voltage: 3.0 V

Battery discharge termination voltage: 3.2 V

Battery: over-current protection current 3 a

NOTE

1. Ampere meter can only be connected to 5v input end of the module.

2. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.

3. The connection wire should not be too thick.

4. Make sure the connect point is good.

5. 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-substract the charging current to avoid burn damage to chip.

6. NO Reveral polarity.
