Claim 0:
1. A controller having a mode of operation including one of an on mode and an off mode, the controller comprising:
a voltage supply node;
a mode of operation signal node;
a powered component;
a switching device coupled in series between the voltage supply node and the powered component; and
a power supply detector coupled to the switching device, the voltage supply node, and the mode of operation signal node, the power supply detector being configured to
receive a mode of operation signal indicative of the mode of operation of the controller from the mode of operation signal node,
determine that the controller is in the off mode based on the mode of operation signal, and
control the switching device to prevent a current from passing from the voltage supply node to the powered component responsive to determining that the controller is in the off mode.
