TP5100 4.2v 8.4v Single Double Lithium Battery Charge Management Lion Battery Compatible 2A Charging Board designed as a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. This charging board comes in an ultra-compact QFN16 package and simple external circuit. This makes TP5100 ideal for portable equipment with so large current charging management applications. Meanwhile, TP5100 features built-in input overcurrent, under voltage, short circuit protection. Along with this it also provides over temperature, and reverse battery shutdown protection.
TP5100 operates at a wide voltage range of 5V-15V, dual battery trickle charge into pre-charge, constant current, constant voltage three-phases, 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 to use smaller capacitors, and peripherals. And also enables maintaining of smaller amount of heat in high current charging. It has charging indicator LED.
TP51OO features built-in power PMOSFET, anti-intrusion circuit, so no anti-intrusion protection and another external Schottky diode. The TP5100 Module is capable of charging either single or double lithium ion cell battery with a maximum charging current of 2A. The default charging mode is for 4.2V. To enable the 8.4V Charging mode, the SET pin needs to be soldered.
