[Retired]Li-MnO2, LiFePO4 (LFP) Charger Board 1A(2A) TP5000 IC

Description

• Size: 18*26 mm
• Default version on 1A current, could modify to 2A
• Note: Input do not support reverse protection, please read the direction carefully before you, otherwise it will burn the board, but not burn like fire. Reverse projection on battery end can only protect IC but not related resistor.

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.
