Description

The SP2526DS23RG is an IC chip that belongs to the USB Supervisory Power Control Switch category, and it is suitable for self-powered and bus-powered Universal Serial Bus (USB) applications. This dual device has two independent power switches, with each switch having low on-resistance and being able to supply 500mA minimum. The fault currents of each switch are limited, and the flag output pin is available to indicate fault conditions to the USB controller. The device has soft start, thermal shutdown, and undervoltage lockout features that prevent damage and ensure the validity of input voltage.
