G525A General Description

The G525A is an integrated high-side power switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

The G525A satisfies the USB standards. The switch's low on-resistance meets USB voltage drop require-ments. 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 elimi-nates the momentary voltage drop on the upstream port that may occur when the switch is enabled in bus-powered applications.

Besides, a thermal shutdown circuit is included to pre-vent catastrophic switch failure caused by increasing power dissipation when continuous heavy loads or short circuit occurs. A under-voltage lockout (UVLO) circuit ensures that the device remains off unless there is a valid input voltage present, and an enable input that is compatible with both 3.3V and 5V logic.

The G525A is a UL recognized component and is available in active-high and active-low versions in 8-pin SOP packages.
