Li-Ion or LiFePO4 charger cell 1A with protection, module with IO TP5000

The charger is designed for charging a lithium cell with a final voltage of 4.2V (Li-Ion) or 3.6V (LiFePO4) with a constant current of 1A. The charging current can be adjusted by replacing or adding a control resistor, see. picture.


Technical parameters:

- input voltage: 4.5-9V
- output voltage: 4.2 or 3.6V (preset 4.2V)
- output current: 0.1–2A (preset to 1A), above 1A only with cooling
- LED indication: charging-red, charged-green
- dimensions 21.5 × 14.5 × 4.2mm

Note:

The type of charged cell is selected by a tin jumper. For a Li-Pol or LiFePO4 cell, the jumper will be unconnected (terminal voltage for charging = 3.6V), for a Li-Ion cell, the jumper will be connected (terminal voltage for charging = 4.2V). The charging current is preset to 1000mA, it can be adjusted by replacing or adding a control resistor. For currents above 1000mA, the IC must be supplemented with a heatsink.

The product is not a stand-alone unit, it requires professional installation.
