TP5100 2A Lithium Battery Charging Module Specification

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 TP5100 ideal for portable equipment so large current charging management applications. Meanwhile, TP5100 built—in input over-current, under-voltage protection, over temperature protection, short
circuit protection, battery temperature monitoring, reverse battery protection.
 TP5100 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. TP5l00 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.
TP5100 built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection and other external Schottky diode.
