TP5100 Dual/Single 8.4V/4.2V Li-ion Battery Charging Module

TP5100 is a step down double 8.4V/4.2V single lithium battery charge management module. It has in-built overcurrent, under voltage, short circuit protection. Along with this it also provides over temperature, and reverse battery shutdown protection.

The TP5100 Module can charge either single or double lithium ion cell battery. It has wide input voltage range of 5V to 18V. It has Maximum charging current of 2A.

The TP5100 Module has frequency of 400Khz switching mode. So it becomes possible to use smaller capacitors, and peripherals. And also enables maintaining of smaller amount of heat in high current charging. It has charging indicator LED.

The default charging mode is for 4.2V. To enable the 8.4V Charging mode, the SET pin needs to be soldered.
