Continuous Load Current 500mA per port Max. ON-Resistance 140mW Max. Short Circuit Current Limit 1.25A Individual Open-Drain Fault Flag Pins ON-State Supply Current 110µA (typ.) OFF-State Supply Current 0.75µA (typ.) Thermal Shutdown Undervoltage Lockout (UVLO) Typically 2.4V 1ms Turn-ON (soft-start) and Fast Turn-OFF Active-High or Active-Low Enable Versions Description GM2526 is a dual high-side integrated power switch with independent enable and flag functions, designed for selfpowered and bus-powered Universal Serial Bus (USB) applications. GM2526 requires few external components. Each of the two switch channels supply up to 500mA as required by USB downstream devices. Each switch’s low on-resistance meets USB voltage drop requirements. Fault current is 750mA (typical). A flag output indicates fault conditions to the local USB controller. The soft-start feature prevents the transient voltage drop on the upstream port that can occur when the switch is enabled in bus-powered applications. Thermal shutdown protection prevents switch failure from high-current loads. Undervoltage lockout (UVLO) hold GM2526 off unless there is a correct input voltage. GM2526 has 3.3V and 5V logic-compatible Enable inputs. GM2526 is available in Active-High and Active-Low versions, and comes in 8-p...
