Bo Mạch Sạc Pin Lithium Tp5100 Tp5000 1a 2a 4.2v 8.4v

TP5100 Description:
TP5100 is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. Its ultra-compact QFN16 package and simple external circuit, making TP5100 ideal for portable equipment so large current charging management applications.Meanwhile, TP5100 built-in input overcurrent, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.

TP5100 have 5V-18V wide input voltage, dual battery trickle charge into pre-charge, constant current, constant voltage three phase, pre-charge current trickle charge current through an external resistor adjustment, the maximum charge current up to 2A. TP5100 with a frequency of 400kHz switching mode makes it possible to use a smaller outer Suo device and the large current charging still maintain a smaller amount of heat.

TP51OO built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection and other external Schottky diode.

TP5000 Product parameters:

TP5000 lithium ion battery lithium iron phosphate battery 1A current 4.2/3.6V
Function: Charge lithium battery and lithium iron phosphate battery. Full of self-stop. Red and green double lights indicate.

Usage: TP4056 4057 charging board usage is the same.
1. The lithium battery only needs to be connected to the 5V power supply, and the output B+B- can be connected to the battery. The red light is on during charging, and the battery is fully charged. The green light is on after charging.
2, for lithium iron phosphate battery 3.6V, just soldering iron to open the tin point between the two pads. The power battery connection method is unchanged as described above. If you need to change the charge to a 4.2V lithium battery, use the pad to solder it
