Abstract
An electronic system (6) has a power management logic circuit (920). A first power supply connector (1902) is electrically coupled to the power management logic circuit (920) and a second power supply connector (1904) is also electrically coupled to the power management logic circuit (920). The power management logic circuit (920) has a first logic section (920A) connected to the first power supply connector (1902), and the first logic section (920A) has a suspend output (SUSPEND#). A second logic section (920B) is connected to the second power supply connector (1904) for operation independent of the first logic section (920A) when power is available at the second power supply connector (1904, RTCPWR) and suspended at the first power supply connector (1902, VCC).
