TP5100 2A Lithium Ion 18650 Battery Charger Module
The TP5100 2A Lithium Ion 18650 Battery Charger Module is a highly efficient dual-switch buck charge management chip designed for 8.4V or 4.2V lithium-ion batteries. Its compact QFN16 package and straightforward external circuit make it ideal for portable devices requiring high-current charging capabilities.
Equipped with comprehensive built-in features, the TP5100 ensures robust protection including input overcurrent, undervoltage, overtemperature, short circuit, battery temperature monitoring, and reverse battery protection.
Operating with an input voltage range of 5V to 18V, the TP5100 charges batteries in three stages: trickle charge, constant current, and constant voltage. The module allows for adjustment of trickle and pre-charge currents via external resistors, supporting a maximum charge current of 2A. Utilizing a 400kHz switching frequency, it minimizes the size of external components and reduces heat generation, particularly advantageous during high-current charging.
With an integrated power PMOSFET and anti-reverse circuitry, the TP5100 eliminates the need for additional external Schottky diodes or reverse protection components, simplifying design and enhancing reliability.
