Introduction
TP4056 is a complete single-cell lithium-ion battery with a constant current/constant voltage linear charger.
The SOP40 package with a heat sink on the bottom of the TP4056 and fewer external components make the TP4056 an ideal choice for portable applications.
TP4056 is suitable for USB power supply and adapter power supply.
Due to the internal PMOSFET architecture and anti-reverse charging path, no external isolation diode is required. Under high power operation or high ambient temperature conditions, thermal feedback will automatically adjust the charging current to limit the chip temperature.
The charging voltage is fixed at 4.2V, and the charging current can be set externally through a resistor. When the charging current reaches the final float voltage and s to 1/10 of the set value, the TP4056 will automatically terminate the charging cycle.
When the input voltage (AC adapter or USB power supply) is removed, the 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, reducing the power supply current to 55uA.
Other features of TP4056 include battery temperature detection, undervoltage lockout, automatic charging, LED status pins for charging and termination.
100% brand new high-quality charging module: linear charging.

 

parameter
Charging accuracy: 1.5%.
Input voltage: 4.5V-5.5V.
Fully charged voltage: 4.2V ± 1%
Current: 1A adjustable.
LED indicator: Red means charging and green means fully charged.
Input interface: micro USB / mini usb / type-c usb
Working temperature: -10° to +85°.
Reverse polarity: No.
Battery overcharge protection voltage: 4.28V
Battery overcharge boost voltage: 4.00V
Battery discharge protection voltage: 3.0V
Battery discharge termination voltage: 3.2V
Battery: Overcurrent protection current 3a
Note: 1. The ampere meter can only be connected to the 5v input terminal of the module.
2. The charging current is preferably 37% of the battery capacity. If you charge a 1000mAH battery, 400 current is enough.
3. The connecting wire should not be too thick.
4. Make sure the connection point is good.
5. The input voltage is too high, such as 5.2v, and the current is less than 1000mA, which is a normal phenomenon. With protection function, the charging current is automatically subtracted to avoid burning the chip.
