UTC US2076 is a dual integrated high-side power switch particularly designed for self-powered and bus-powered Universal Serial Bus (USB) applications. The UTC US2076 meets the requirements of the USB. The low on-resistance of the switch satisfies USB voltage drop requirements. Fault current is limited to typically 750mA, well below the UL 25VA safety requirement. Flag outputs are available to indicate fault conditions to the local USB controller. In addition, soft start can eliminate the momentary voltage drop which is generated on the upstream port that may occur when the switch is enabled in bus-powered applications.
