... 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 ...

... Once this current-limit thresh- old is exceeded the device enters constant-current mode. This constant current is specified as the short-circuit current- limit in the “Electrical Characteristics” table important to note that the MIC2536 will deliver load current up to the current-limit threshold before entering current-limited opera- tion. Fault Flag FLGx is an open-drain N-channel MOSFET output ...

... This “soft-start” feature effec- = 6V) even for a short tively isolates power supplies from highly capacitive loads by reducing inrush current. Figure 2 shows how the MIC2536 may be used in a hot-plug card application. Overcurrent Transients The MIC2536 incorporates an internal circuit designed to prevent FLG from being asserted due to transient inrush current. Overcurrent events < ...

... MIC2536 Universal Serial Bus (USB) Power Distribution Applications The MIC2536 is ideally suited for USB (Universal Serial Bus) power distribution applications. For Bus-Powered hubs, USB requires that each downstream port be switched on or off under control by the host four downstream ports each capable of supplying 100mA at 4.4V minimum are allowed. In ...
