Battery Charger Charging Module TP5100 For 18650–OKY3399-6

This charger module, based on the TP5100 IC, provides a complete and efficient solution for charging single-cell (4.2V) or dual-cell (8.4V) Li-Ion and Li-Po batteries.
Its high-frequency (400 kHz) switching design ensures low heat generation and allows for a compact footprint, making it ideal for integration into custom electronics projects.


Key Features

- Versatile Charging: Configurable for charging either one Li-Ion/Li-Po cell to 4.2V or two cells in series to 8.4V.

- Wide Input Voltage: Operates on a flexible input voltage range from 5V to 18V.

- Stable Output: Delivers a regulated charging current of up to 1.5A for this module.

- Intelligent Charging: Utilizes a three-stage process (trickle, constant current, constant voltage) to safely and fully charge batteries.

- Comprehensive Protection: Integrated safety features protect against overcurrent, undervoltage, over-temperature, short circuits, and reverse battery connection.

- Status Indicator: An onboard dual-color LED provides instant visual feedback on the charging status.
