The MIC2012-2PZQS from Microchip Technology is a dual-channel USB power switch. It is engineered to support power distribution requirements for USB Wakeup from the ACPI S3 state. This device can switch its two outputs between a 5V main supply and a 5V auxiliary supply, commonly found in ATX power supplies.
The MIC2012-2PZQS adjusts its current-limit threshold based on the ACPI state. In the active S0 state, the current-limit is set at a minimum of 500mA per channel, meeting USB continuous output current specifications. In the S3 state, the current-limit can be reduced to 100mA per channel to minimize auxiliary supply current and maintain voltage regulation during fault conditions.
This USB power controller provides make-before-break switching for glitch-free transitions between S3 and S0 states. Its thermally isolated channels ensure that a fault in one channel does not affect the other. Fault status outputs signal overcurrent and thermal shutdown conditions. The device is available in a 16-QSOP package and operates within a temperature range of 0°C to 70°C.
Applications include desktop PCs, notebook PCs, notebook docking stations, LAN servers, and PC motherboards.
