Protections and Safety

• Overvoltage protection prevents battery overcharging
• Overcurrent protection limits charging current to protect battery and circuit
• Thermal protection reduces charge or shuts down when the module overheats
• Automatic recharge restarts charging when battery voltage falls below a threshold

Typical Applications

• Power banks and portable battery packs
• Battery management and charging circuits for single-cell devices
• Robotics, drones, and remote-controlled devices
• IoT devices and energy storage modules
• DIY electronics and hobbyist projects that require fast, safe charging

Integration and Wiring Tips

• Use a stable 5V DC supply (USB or adapter) capable of delivering the desired charging current plus margin.
• Place the module away from heat sources and allow airflow for best thermal performance.
• Route battery and input wires carefully to minimize voltage drop; use thicker wires for higher currents up to 3A.
• Verify polarity before connecting the battery to avoid damage to the module and battery.
• Consult the IP2312 datasheet for exact pinout and recommended external components when designing into a custom PCB.
