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. In addition, it allows for a lesser quantity of heat to be maintained during high-current charging. It is equipped with a charging indication LED.
The TP51OO has a built-in power PMOSFET, no anti-intrusion circuit, and another external Schottky diode. With a maximum charging current of 2A, the TP5100 Module can charge either a single or double lithium ion cell battery. The charging mode is set to 4.2V by default. The SET pin must be soldered to enable the 8.4V Charging mode.
