HW-370 TP5100 2A Li Ion Battery Charger Module

HW-370 TP5100 2A Li Ion Battery Charger Module
Description
TP5100 charger module is a 2A Lithium-Ion 18650 Battery Charger Module is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. TP 5100 module is ultra-compact QFN16 package and simple external circuit, making it ideal for portable equipment so large current charging management applications. Meanwhile, it’s built-in input overcurrent, under voltage protection, over-temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.

TP5100 have 5V-15V wide input voltage, dual battery trickle charge into pre-charge, constant current, constant voltage three phases, pre-charge current trickle charge current through an external resistor adjustment, the maximum charge current up to 2A. 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.

It has a built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection and other external Schottky diode.
