The G525A satisfies the USB standards. The switch's low on-resistance meets USB voltage drop requirements. When the output load exceeds current-limit threshold, G525A switches into constant mode and limit the output current to a safe level, which is typically 1.4A, well below the UL 25VA safety requirements. An open-drain flag output is also available to indicate fault conditions to the local USB controller. Soft start eliminates the momentary voltage drop on the upstream port that may occur when the switch is enabled in bus-powered applications.
