Gamma GM2526
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. 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.| Part No. | GM2526 |

FEATURES
Compliant to USB Specifications Two Independent Switches Input from 3V to 5.5V Min. 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 VersionsDESCRIPTION
GM2526 requires few external components. 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-pin DIP and SOIC packages.
