Description
TP5100 is a dual 8.4 V buck switch, a single cell 4. 2 V battery management chip for lithium battery. its ultra-compact QFN16 package and simple external circuitry, making TP5100 ideal for equipment management applications such large portable charging current. While that, TP5100 built-in overcurrent protection input, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.
TP5100 has 5 V-18 V of wide input voltage, dual battery slow charge in pre-charge, constant current, constant voltage three-phase, pre-adjustment of trickle charge current load current through an external resistor, maximum load current up to 2A. TP5100 with a frequency of 400 kHz switching mode makes it possible to use a smaller Suo outer device and the large load current still maintain a lower amount of heat.
TP51OO internal PMOSFET power, anti-intrusion circuit, so there is no anti-intrusion protection and other external Schottky diode.
