Abstract: One example includes a power control system. The power control system includes an activation controller that is powered via a first power voltage generated via a first power supply and is configured to provide an enable signal. The activation controller can assert the enable signal in response to an input activation signal to control activation of a second power supply. The second power supply can generate a second power voltage in response to the enable signal being asserted. The second power voltage can be provided to regulate power associated with ancillary electronic circuitry. The system also includes a deactivation controller that is powered via the second power voltage and is configured to generate a disable signal to de-assert the enable signal in response to one of a plurality of predetermined deactivation conditions.
