... FAULT2 is asserted LOW when channel thermal shutdown state or overcurrent condition for more than 5ms. MIC2070 latches this output in it's asserted state upon overcurrent condition. Toggling EN2 or removing load will reset the circuit breaker latch, and deassert FAULT2. 3 Micrel MIC2010/2070 ...

... The MIC2010/2070 are designed to support the power distri- bution requirements for 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 500m MOSFET switch from the AUX input to each of its two outputs ...
