The DIO7164HAST5 from Dioo Microcircuits is a Low Loss Power Distribution Switch that has been designed for applications where precision current limiting is required or heavy capacitive loads and short-circuits are encountered. It requires an input voltage of 2.7 - 5.5 V. This power switch can control rising and falling times to minimize current surges when turned ON or OFF. It limits the output current to a safe level by using a constant current mode when the output load exceeds the current limit threshold and offers reverse blocking and over-temperature protection functions to prevent abnormal conditions. This power switch IC is available in a surface-mount package and is ideal for USB ports/hubs, digital TV, set-top boxes, and VOIP phone applications.
