4.5-12V 3A Lithium Battery Charging Module Type-C Interface Charging and Protection Integrated Power Module for DIY

4.5-12V 3A Lithium Battery Charging Module Type-C Interface Charging and Protection Integrated Power Module for DIY Description

This module adopts the TI-specific battery charging chip BQ25606 step-down solution, featuring high output efficiency, stable performance, and overcharge and overdischarge protection.
Type-C interface input, the input voltage range is 4.5-12V, and the maximum output current can reach 3A.
It is very suitable for charging lithium batteries with a nominal 3.7V. The board is equipped with a red LED charging indicator light and a LED status indicator light, allowing for a direct observation of the charging status of the module and the battery.

Introduction to Parameters

Module type: Step-down power supply

Input voltage: DC4.5-12V

Charging cut-off voltage: 4.2V 1%

MAX charging current: 3000mA

Battery over-discharge protection voltage: 3V

Battery overcharge protection voltage: 4.2 0.05V

Module interface: Pad (2.54mm pin headers can also be connected)

1. When connecting the battery for the first , there may be no voltage output at the U terminal. It is necessary to connect a 5V battery to the power input terminal to charge it and activate the protection circuit. When using a mobile phone charger for power supply, it must be able to output more than 1A; otherwise, the charging may not be normal.

2. The module is not designed for high power, but it is suitable for charging most of the nominal 3.7V lithium batteries of jue. Therefore, when in use, do not exceed the limit values tested below, especially for the load current. It is recommended to operate below 2A. If it exceeds 2A, a heat sink needs to be added for heat dissipation.

3. Regarding the status of indicator lights:
