Description
The standard way to make a project rechargeable. The TP4056 charges the cell with the correct CC/CV profile to 4.2 V, and the DW01A protection chip with a dual MOSFET disconnects the load if the battery runs too low or is shorted.
Features
- USB Type-C input, 5 V
- Charge current 1 A (set by a resistor – can be lowered)
- Charge voltage 4.2 V ±1 % – for one Li-ion / LiPo cell only
- Protection: over-discharge (about 2.5 V), over-charge, over-current and short-circuit
- Red LED while charging, blue/green LED when full
- Pads: IN+ / IN−, B+ / B− (battery), OUT+ / OUT− (load)
Important
Connect the cell to B+ / B− and your circuit to OUT+ / OUT− so the protection works. Only for single-cell (1S) batteries – never for 2S packs, NiMH or lead-acid. For small cells (below about 1000 mAh) lower the charge current by changing the R_PROG resistor.
