Summary of USB BATTERY CHARGER CIRCUIT WITH PIC16F629
The USB Battery Charger Circuit uses a PIC16F629 microcontroller to safely charge AAA batteries via a computer’s USB port. It includes a 7805 voltage regulator to provide stable 5V power from USB or an external adapter (9V-12V). The charging current allows the battery to fully charge in 1 to 14 hours, indicated by a dual-color LED and buzzer warning system. The circuit limits current draw to safe USB levels (100 mA) and protects against short circuits using a capacitor. Microcontroller assembly and hex files are provided for implementation.
Parts used in the USB Battery Charger Circuit with PIC16F629:
- PIC16F629 microcontroller
- 7805 voltage regulator IC
- Dual-color LED
- Buzzer
- Capacitor C1
- AAA battery (for charging)
- USB port connector
- 9V or 12V power adapter (optional)

Besleneeg from the USB port in the circuit diagram for the circuit in 7805 will use a 5 volt regulator IC that you do not want to use the USB port with an adapter 9v 12v going to use … 7805 should be installed .. USB battery charging circuit assembly prepared with the resources of the microcontroller software. Asm and. Hex file there.
PIC16F629 USB BATTERY CHARGER
USB devices may draw from the PC up to 100 mA. The larger current can subscribe only when it is requested in the configuration descriptor and Energy approves the operating system. That in this charger does not, and therefore may not work in any PC. For this reason, the mind staffed capacitor C1, which when turned on will draw a large current for a long time and fungi that can (and should) be evaluated as a short circuit and disconnect the USB port.
