TP5100 kettős egylítium akkumulátor töltéskezeléssel kompatibilis 2A újratölthető lítiumlemez
TP5100 double single lithium battery charge management compatible 2A rechargeable lithium plate
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.
