Abstract
A chip includes a first pin coupled to a signal line and a controller to detect a state of the signal line using the first pin. The controller controls output of first power to the signal line through the first pin based on a first state of the signal line and prevents output of the first power to the signal line through the first pin based on a second state of the signal line. The signal line may be coupled to provide second power from a power source to a data storage device.
