Final Information
General Description
The MIC2536 is a cost-effective high-side power switch, with
two independently controlled channels, optimized for bus-
powered Universal Serial Bus (USB) applications. Few exter-
nal components are necessary to satisfy USB requirements.
Each switch channel of the MIC2536 will supply up to 100mA
as required for USB bus-powered downstream devices. Fault
current is limited to typically 275mA by fast-acting current-
limit circuitry which minimizes voltage droop on the upstream
port during fault conditions. A flag output with transient filter
indicates fault conditions to the local USB controller but will
ignore short flag signals resulting from inrush current during
hot plug-in events.
Soft start eliminates the momentary voltage droop on other
ports that may occur when the switch is enabled in bus-
powered applications. Additional features include thermal
shutdown to prevent catastrophic switch failure from high-
current loads and 3.3V and 5V logic compatible enable
inputs.
The MIC2536 is available in active-high and active-low ver-
sions in 8-lead SOP and MSOP.
