TP 5100 4.2v and 8.4v Dual One/Two Battery Protection Board

Meanwhile, TP5100 built-in input overcurrent, under-voltage protection, over-temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.

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.
