TP5100 4.2v 8.4v Single Double Lithium Battery Charge Management Lion Battery Compatible 2A Charging Board 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 for large current charging management applications. TP5100 has 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. TP5100 with a frequency of 400kHz switching mode makes it possible to use a smaller outer Suo device, and the large current charging still maintains a smaller amount of heat. TP51OO built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection, and another external Schottky diode.
