TP5100 4.2V And 8.4V 2A 18650 Lithium Battery Charging Protection

TP5100,TP5100 module ,TP5100 charger or TP5100 charger module is 2A Lithium-Ion 18650 Battery Charger Module is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. TP5100,TP5100 module ,TP5100 charger or TP5100 charger module is 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 overcurrent, 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 phases. Pre-charge current trickle charge current through an external resistor adjustment, the maximum charge current up to 2A. TP5100 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.
