Soldered Li-ion Charger with Protection (USB-C)
Overview
The Soldered 333014 is a compact lithium-ion battery charging module featuring a modern USB Type-C interface and integrated protection circuitry. It utilizes CC/CV (Constant Current/Constant Voltage) charging logic to safely manage batteries with a maximum output current of 1000mA. The board simplifies power management in portable projects by combining a charging controller and safety features into a single 22mm x 38mm footprint.
Why Choose This Part
This module provides comprehensive safety features including short-circuit, over-voltage, and under-voltage protection to prevent battery damage. The inclusion of both a female USB Type-C port and a JST battery connector allows for rapid integration without custom soldering for the primary power path.
Applications
Getting Started
Connect a 4.5V to 5.5V source to the USB Type-C input and attach a compatible 3.7V Li-ion cell to the JST connector or the designated battery pads. Monitor the onboard status LEDs to determine charging state and ensure the input current capability matches the 1000mA demand.
