USB HIGH-SIDE POWER SWITCH ADVANCE INFORMATION
- DESCRIPTION
The UTC US1528 is an integrated high-side power switch. It is designed particularly for self-powered and bus-powered USB (Universal serial bus) applications.
The UTC US1528 meets the requirements of the USB. The low on-resistance of the switch meets USB voltage drop requirements. When the output load bees higher than the current-limit threshold, the UTC US1528 switches into constant- current mode and limits the output current at 1.4A (TYP).
An open-drain flag, playing a role as the MOSFET output, is included to indicate error conditions to the local USB controller. A...
