TP5000 2000MA Single Section Switch Type
Description:
TP5000 is a switch step-down single-cell lithium manganese battery / lithium iron phosphate battery charge management chip. Its QFN16 ultra-small package and simple peripheral circuits make the TP5000 ideal for high-current charging management applications in portable devices. At the same time, TP5000 has built-in input overcurrent, undervoltage protection, chip overtemperature protection, short circuit protection, battery temperature monitoring, battery reverse connection protection.
The TP5000 has a wide input voltage. The battery charging is divided into three stages: trickle precharge, constant current, and constant voltage. The trickle precharge current and constant current charging current are adjusted by external resistors, and the maximum charging current is 2 A. TP5000 mining
The switching operating mode with a frequency of 800 kHz makes it possible to use smaller peripheral devices and still maintain a small amount of heat generation during high-current charging. TP5000 has built-in power PMOSFET and anti-backflow circuit, so no external protection such as anti-backflow Schottky diode is needed. The constant current function of TP5000 can also be used in the input of 2 strings of lithium batteries or 4 strings of dry batteries. The constant current drives 0.5-7W white LEDs.
