  • Publication number: 20180097398
    Abstract: In one example, a circuit includes an input, an output, and a control module. The input is configured to receive a control signal indicating whether to activate or deactivate a load. The output is configured to supply current to activate the load. The control module is configured to determine whether a state of the circuit is a low current consumption mode (LCCM). In response to determining that the state of the circuit is not the LCCM, the control module is configured to determine whether the control signal indicates to activate the load and output, at the output, the current to activate the load. In response to determining that the state of the circuit is the LCCM, the control module is configured to ignore the control signal indicating whether to activate or deactivate the load and output, at the output, the current to activate the load.
