How to use TP5100 2A 8.4/4.2V 1S and 2S Lithium Battery Charger DIY
TP5100 is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. This article is going to introduce detailed information about TP5100 for you to understand how to use it.
TP5100
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.
