TP5100 2A Lithium Ion 18650 Battery Charger Module
The TP5100 2A Lithium Ion 18650 Battery Charger Module is a dual-switch buck charge management chip for 8.4V or 4.2V lithium batteries. It has a compact QFN16 package and a simple external circuit, making it suitable for portable devices that require large current charging. The TP5100 also has built-in features such as input overcurrent, undervoltage, overtemperature, short circuit, battery temperature monitoring, and reverse battery protection.
The TP5100 can accept an input voltage range of 5V-18V and charge the battery in three stages: trickle, constant current, and constant voltage. The trickle and pre-charge currents can be adjusted by an external resistor, and the maximum charge current can reach 2A. The TP5100 uses a 400kHz switching frequency, which allows it to use smaller external components and generate less heat during high current charging.
The TP5100 has an integrated power PMOSFET and an anti-reverse circuit, so it does not need any external Schottky diode or anti-reverse protection.
