G526 - Dual USB High-Side Power Switch
The G526 is a dual integrated high-side power switch with independent enable and flag functions, optimized for self-powered and Universal Serial Bus Powered Bus (USB) applications. The G526 meets the following USB requirements: The switch's low on-resistance meets USB voltage drop requirements; fault current is limited to typically 750mA, well below UL25VA safety requirements; a flag output can indicate fault conditions to the local USB controller. Soft-start eliminates transient voltage drops on upstream ports that can occur when switching is enabled in bus-powered applications. Additional features include thermal shutdown to prevent catastrophic switching failure from high current loads, undervoltage lockout (UVLO) to ensure the device remains off unless a valid input voltage is present, and enable input, both 3.3 compliant V and 5V logic. The G526 is available in active-high and active-low versions in an 8-pin SOIC package.
