Description
GM2526 is a dual high-side integrated power switch with in-
dependent enable and flag functions, designed for self-
powered and bus-powered Universal Serial Bus (USB) ap-
plications. 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-pin DIP and SOIC packages.
