The TP5100 IC is a step-down switching double 8.4V / 4.2V single lithium battery charge management chip. QFN16 ultra small package with its simple external circuit, so that the large current charging management application TP5100 ideal for portable devices. Meanwhile, TP5100 built-in input overcurrent, under voltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.

The TP5100 IC has a wide input voltage 5V-18V, the battery trickle charging into pre-charge, constant current, constant-voltage three phase, pre-charge current trickle charge current is adjusted through an external resistor, the maximum charging current of 2A. TP5100 using frequency of 400kHz switching mode makes it possible to use a smaller peripheral devices, and still maintain a smaller amount of heat in the large current charging. TP5100 built-in power of the PMOSFET, anti-intrusion circuit, there is no need peripheral anti-intrusion protection Schottky diode.
