$1.50 AUD inc. GST
The TP4056 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries.
The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor.
The TP4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
You can safely charge lithium cells in 3 stages with this IC, up to a max voltage of 4.2v.
