Understanding of TP5100 2A Lithium Battery Charger Module [FAQ]

The TP5100 is a single cell 4. 2V lithium battery charge management chip with a double switch buck of 8.4V. The TP5100  is suited for portable equipment and large current charging management applications because of its ultra-compact QFN16 packaging and easy external circuit. Meanwhile, the TP5100 has input overcurrent, under-voltage, over-temperature, and short circuit battery temperature monitoring, and reverse battery protection built-in.

The TP5100 offers a wide input voltage range of 5V  to 18V, dual battery trickling charge into pre-charge, constant current, constant voltage three-phase, pre-charge current trickle charge current via an external resistor adjustment, and a maximum charge current of 2A. The TP5100  's switching mode operates at a frequency of 400kHz, allowing for the use of a smaller outer Suo device while still maintaining a low level of heat.

TP5100 Circuit

Both the TP5100 and the TP4056 are charging and protection modules that can do their jobs rather well. However, the TP5100 module outperforms the TP4056 module in terms of power and functionality, while the TP4056 module outperforms the TP5100 module in terms of cost and availability.
