... USB wakeup from the ACPI S3 state. It integrates two independent channels under control of input S3#. When S3# is asserted LOW (ACPI S3 state) the MIC2010/ 2070 will switch a 500mΩ MOSFET switch from the AUX input to each of its two outputs. In addition the current-limit threshold will be set to a value specified by a resistor connected to the RSET inputs ...
