A double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip is used in the TP5100 4.2v 8.4v Single Double Lithium Battery Charge Management Lion Battery Compatible 2A Charging Board. The TP5100 is ideal for portable equipment and large current charging management applications due to its ultra-compact QFN16 package and simple external circuit. Meanwhile, the TP5100 has built-in input overcurrent, undervoltage, over-temperature, short circuit, battery temperature monitoring, and reverse battery protection.
The TP5100 has a wide input voltage range of 5V-15V, dual battery trickle charge into pre-charge, constant current, constant voltage three-phases, pre-charge current trickle charge current through an external resistor adjustment, and a maximum charge current of 2A. The TP5100 switching mode with a frequency of 400kHz allows for the use of a smaller outer Suo device while maintaining a lower amount of heat.
The TP51OO has a built-in power PMOSFET, no anti-intrusion circuit, and another external Schottky diode.
