Brief About TP5100 Module
The TP5100 charging module consists of a TP5100 IC, an inductor for the integrated switch mode supply, resistors for voltage and current setting and sensing, and capacitors for decoupling.
How To Use TP5100 Module
The TP5100 module is an integrated single or dual cell Lithium battery charger. The four power inputs and outputs are IN+, which is the input voltage pin that accepts 5V to 18V, BAT+ which is the battery output and connects to the positive battery terminal, and two GND pins for the input and output. There is also a header for the charging and charged indicator LEDs, with a common center pin.
All TP5100 modules have a jumper called ‘SET’ that sets the output voltage since this module can be used to charge both single and dual cell batteries. Shorting the SET jumper sets the charge voltage to dual cells.
