Battery Charger and Power Bank Project Using IP5306

This project is a versatile, beginner-friendly power bank and battery charger based on the IP5306 integrated circuit. It is designed to provide efficient battery management, USB power output, and user-friendly operation, making it an ideal project for students starting in electronics.

Features:

• Power Input: The circuit is powered through the USB Type-C connector (J1) with a 5V DC input, ensuring compatibility with modern charging standards.
• Power Output:
• USB Output: The USB-A female connector (J2) provides a standard 5V DC output for charging USB devices.
• Terminal Block Output: The terminal block (J3) offers an additional 5V DC output for direct connection to other devices or circuits.
• Battery Charge Indicators: The LEDs (D1, D2, D3, and D4) display the battery's charge status:

1. D1: 25% charge
2. D2: 50% charge
3. D3: 75% charge
4. D4: 100% charge

• Push Button Functionality (SW1):
• A single press powers on the power bank.
• A double press powers off the power bank.
• A long press activates LED D5, which functions as a small flashlight.

Educational Benefits:

This project is perfect for students new to electronics, as it introduces fundamental concepts like:

Battery charging and power management using the IP5306 IC.

Understanding USB power input/output and terminal block connections.

Implementation of multi-function buttons for user control.
