HW-370 TP5100 2A Li-Ion Battery Charger Module 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, make TP5100 ideal for portable equipment and large current charging management applications. Meanwhile, TP5100 has built-in input overcurrent, under voltage protection, over-temperature protection, short circuit protection, battery temperature monitoring, and reverse battery protection.

TP5100 has 5V-18V 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, and 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.

TP5100 built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection, and another external Schottky diode.
