And still retain the input voltage wiring solder joints, can be very convenient DIY
Input voltage: 5V
Charge cut-off voltage: 4.2V ± 1%
Large charging current: 1000mA
Battery over discharge protection voltage: 2.5V
Battery overcurrent protection current: 3A

Usage method:

Attention: When connecting the battery for the first time, there may be no voltage output between OUT+and OUT -. At this time, connecting 5V voltage to charge can activate the protection circuit. If the battery is short circuited from B+B - and then connected, it also needs to be charged to activate the protection circuit. When using a mobile phone charger as an input, it is important to note that the charger must be able to output 1A or above, otherwise it may not charge properly. The TYPEC USB socket and the+- pad next to it are the power input terminals, connected to 5V voltage. B+is connected to the positive pole of the lithium battery, and B - is connected to the negative pole of the lithium battery. OUT+and OUT - are connected to loads, such as the positive and negative poles of a mobile boost board or other loads. Connect the battery to B+B -, insert the phone charger into the USB socket, the red light is on to indicate charging, and the blue light is on to indicate full charge.

TC4056A is a complete single-cell lithium-ion battery constant current/constant voltage linear charger. Its ESOP8/DIP8 package with a heat sink on the bottom and a small number of external components make TC4056A an ideal choice for portable applications. TC4056A can work with USB power and adapter power. Due to the internal PMOSFET architecture and anti-reverse charging circuit, no external isolation diode is required. Thermal feedback can automatically adjust the charging current to limit the chip temperature under high power operation or high ambient temperature conditions. The charging voltage is fixed at 4.2V, and the charging current can be set externally through a resistor. When the charging current drops to 1/10 of the set value after reaching the final float voltage, TC4056A will automatically terminate the charging cycle. When the input voltage (AC adapter or USB power) is removed, TC4056A automatically enters a low current state to reduce the battery leakage current to less than 2uA. The TC4056A can also be placed in shutdown mode when powered, reducing the supply current to 55uA. Other features of the TC4056A include battery temperature detection, undervoltage lockout, automatic recharge, and two LED status pins for indicating charging and completion. II. Features
