TP5100 2A Lithium Battery Charging Module

The TP5100 is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. Its ultra-compact QFN16 package and simple external circuit, making its ideal for portable equipment so large current charging management applications. Meanwhile, Its built-in input overcurrent, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection. Its have 5V-18V wide input voltage, dual battery trickle charge into pre-charge, constant current, constant voltage three phase, pre-charge current trickle charge current through an external resistor adjustment, the maximum charge current up to 2A.

This is with a frequency of 400kHz switching mode makes it possible to use a smaller outer Suo device and the large current charging still maintain a smaller amount of heat. Its built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection and other external Schottky diode.
