This part of the circuit is to output 8.4V to charge the lithium battery.
TP5100 is a switching step-down dual-cell 8.4V/single-cell 4.2V lithium battery charge management chip.
TP5100 has a wide input voltage of 5V-18V. The battery charging is divided into three stages: trickle precharge, constant current, and constant voltage. The trickle precharge current and constant current charging current are adjusted by external resistors, and the maximum charging current is up to 2A.
We are a professional lithium battery factory in China. Now we briefly introduce how to produce lithium batteries. It starts from cathode & anode mixing, coating, baking, calendering, automatic slitting & cutting, winding, top & side sealing, electrolyte injection, pressing formation, forming, capacity grading, OCV1 & OVC2, cell to PCB, insulation and shipping.
