TP5100 double single lithium charge management compatible 2A rechargeable lithium plate 18650 4.2V 8.4V
Product Parameters
Size: 25*17*5mm ultra small size
Input voltage: 5-18V DC power supply
Charging status: full and no-load blue light, red during charging
The voltage setting should be operated in the power-off state. When the switching switch is installed, the input should be disconnected and then switched.
Can also be used for white LED constant current drive: set a single lithium drive, set up a dual lithium drive 2 strings
Detailed 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.
