matters needing attention:
When charging, the load on the out terminal should be disconnected, and the input terminal has a micro USB female base, which can directly use the mobile phone charger as input to charge the lithium battery, and still keep the input voltage wiring solder joint, which is very convenient for DIY.
 
Input voltage: 5V
Charging cut off voltage: 4.2 ± 1%
Maximum charging current: 1000mA
Battery over discharge protection voltage and current: 2.5V/3A
Board size: 2.8 * 1.7cm
 
How to use it
when the battery is connected for the first time, there may be no voltage output between out + and out -. At this time, the protection circuit can be activated by charging with 5V voltage. If the battery is short opened from B + B - and connected again, it needs to be charged to activate the protection circuit. When using the mobile phone charger as input, pay attention to the charger must be able to output 1A or above, otherwise it may not be able to charge normally. The micro usbt mother base and the + - pad next to it are the power input terminals and connected with 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 ut - are connected with loads, such as moving the positive and negative electrodes of the rising plate or other loads. Connect the battery to B + B -, plug in the mobile phone charger to the USB base. If the red light is on, it means charging, and if the green light is on, it means full charge.
 
Performance overview：
1. On board tp4056 lithium battery charging management chip
2. Mini USB connector on board can be directly connected to JSB port of computer for charging
3. The charging board can also supply power through (in + - and in -) pins
4. The TEM pin arrangement interface is reserved, which can be used for the quality test of lithium battery
5. Input voltage: 4v-8v, maximum output charging current: 1000mA
6. When charging, D1 indicator light is on, and D2 indicator light is on after charging
7. PCB board size: 37mm) × 15mm
 
Product description
Tp4056 is a complete single Li ion battery with constant current / constant voltage linear charger. The sop8 package with heat sink at the bottom and a small number of external components make tp4056 an ideal choice for portable applications. Tp4056 can be suitable for USB power supply and adapter power supply.
Due to the internal PMOSFET architecture and anti overcharge circuit, no external isolation diode is needed.
The 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 via a resistor. When the charging current drops to 1 / 10 of the set value after reaching the final floating charge, tp4056 will automatically terminate the charging cycle. When the input voltage (AC adapter or USB power supply) is removed, tp4056 automatically enters a low current state, reducing the battery leakage current to less than 2ua. Tp4056 can also be placed in shutdown mode when there is power supply to reduce the power supply current to 55ua.
Other features of tp4056 include battery temperature detection, undervoltage locking, automatic recharging and two LED status pins for indicating charging and ending.
