TP5100 double single lithium battery charge 2A

SKU: SLY3402 Category: Lipo Batteries

Product Description

TP5100 is a 8.4V dual buck switch, single cell 4.2V lithium battery charging management chip. Its ultra-compact QFN16 package and simple external circuitry, making TP5100 ideal for portable equipment, hence large current load management applications. Meanwhile, TP5100 built-in input over current, under voltage protection, over temperature protection, short circuit protection, battery temperature monitoring, battery reverse protection.

TP5100s have 5V-18V wide input voltage, dual battery pre-charge, constant current, three-phase constant voltage, pre-charge current trickle charge current through external resistance adjustment, the current of maximum load up to 2A. TP5100 with a frequency of 400kHz switching mode makes it possible to use a smaller external Suo device, and the large current load still maintains a smaller amount of heat.
TP51OO built-in power supply PMOSFET, anti-intrusion circuit, so no anti-intrusion protection and other external Schottky diode.
