Dual USB Host/Hub Output with Constant Current Limit/Protection
This project has 2 outputs that enable us to power up 2 USB devices simultaneously from an input supply of 12-30V DC. The idea of this project is to have safe power for USB powered devices. The circuit is designed to simplify USB port power delivery based on self-powering 2 port USB HOST/HUB. IC provides two constant current outputs each of 1.1Amp 5V DC, and when any of USB port is overload/short circuit, the fault flag goes from high to low, and the outputs are in constant current mode. The project can be used as a dual-port USB charger in cars or trucks.
