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 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 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.

I contacted the manufacturer due to failures. The Circuit when used with DC adapters must have a series 0.1 Ohm resistor and a 100uF capacitor to prevent surge currents from damaging the IC. Haven’t had any failure since. Just a tip in case you see this going up in smoke.

Not sustaining for more than three days. it is going out of order very fast. Please arrange other reliable 8.4V charger module in future.
