Abstract
A smart power management unit (SPMU) apparatus and method of intelligently switching from a “disconnect mode” to a “connect mode” in regards to power-supplying to a paired downstream load device by programmatically monitoring whether there is change in state of the manual switch of the load device, is provided. The SPMU comprises relay module configured to operate in either operation mode (connect mode) or monitor mode (disconnect mode), and controller module configured to determine the operating mode of relay module. When in monitor mode, relay module is configured to disconnect the power supply from the load device while simultaneously enable a monitoring means configured to monitor a change in state of the manual switch. Upon monitoring a change in state of the manual switch based on a response signal supplied from the monitoring means, the controller module switches the relay module from monitor mode to operation mode.
