GENERAL DESCRIPTION The MIC2010 is a dual-channel USB power switch designed to support USB wake-up power distribution requirements from ACPI S3 states. The MIC2010 will switch directly to a 5V-style power supply between the two main supplies and the 5V auxiliary output where the ATX power supply typically provides. The MIC2010 will adjust its current l...

The LTC®4413 contains two monolithic ideal diodes, each capable of supplying between 2.5V and 5.5V from the input voltage to 2.6a. Each uses a 100mΩ ideal diode P-channel MOSFET to connect VTA to OUTA and IBA to OUTB. In normal forward operation the voltage drop across these diodes is as low as 28mV per regulator. Diode currents up to 1A with quiescent current les...
