REVISION HISTORY ................................................................................................................ 14 Nuvoton Confidential Publication Date: Jul., 2009 Revision A0 - II - NCT3012S 1. GENERAL DESCRIPTION The NCT3012S is Nuvoton’s advanced power control IC which is specifically designed for desktop, notebook and any embedded system applications. The NCT3012S provides a mechanism to further lower the total system power consumption while the system is in S5 state. The NCT3012S could block the entire system standby power that comes from the ATX power supplier while the system is in S5 state, and it is fulfilled via the control of the external transistor. The NCT3012S is the only active IC under that circumstance so the total system power consumption is minimized. The system standby power could be resumed by the pushing of the external power button. The NCT3012S is powered by the 5VSB from the ATX power supplier, and communicates with the system through 2-wire System Management Bus (SMBusTM) serial interface. The package is 8-pin ESOP green package. Nuvoton Confidential Publication Date: Jul., 2009 Revision A0 -1- NCT3012S 2.
