About TP5000 IC:
TP5000 is a switch voltage-down lithium manganese battery / lithium iron phosphate battery charge management chip. Its ultra-small QFN16 package and simple peripheral circuit, making it ideal for portable devices which need large current charging management applications.
Meanwhile, TP5000 built-in input overcurrent, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.
TP5000 has a wide input voltage into trickle charge the battery pre-charge, constant current, constant voltage three phase, Trickle pre-charge current, charge current is adjusted through an external resistor, the maximum charging current up to 2A.
TP5000 with a frequency 800kHz switching mode makes it possible to use a smaller peripheral devices, and high-current charging remains smaller heat. TP5000 built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection Schottky diodes, and other peripherals.
TP5000 constant current function, but also can be used in two series lithium batteries or four string input, constant current drive 0.5-7W white LED.
