TP5000 (2A Switching Charger IC for 4.2V Lithium-Ion Battery & 3.6V LiFePO4 Battery)

2024-01-12
▲Description
■TP5000 is a switching buck single manganese lithium battery / LiFePO4 battery charge management chip. Its QFN16 ultra-compact package with simple peripheral circuit, making the TP5000 is ideal for portable equipment 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, divided into three stages Trickle pre- charge, constant current, constant voltage trickle charge the battery pre-charge current, constant current charging current adjusted through an external resistor, the maximum charging current of 2A. TP5000 switching frequency of 800kHz operating mode so that it can use smaller external components and smaller heat remains in the high current charging. TP5000 Built-power the PMOSFET, anti-intrusion circuit, so there is no need anti-intrusion perimeter protection Schottky diodes. TP5000 constant current function can also be used dry batteries in 2 strings of lithium batteries or 4 string input, constant current drive 0.5-7W white LED.
