Voltage droop control

A method for controlling voltage droop, the method comprising:

• receiving a first voltage at a first input of a first component of a device;
• charging a first internal power supply of the first component using an external power supply in response to the first voltage corresponding to a first logical value;
• receiving a voltage at an input of a voltage detector from the first internal power supply in response to the first voltage corresponding to the first logical value,
• coupling the input of the voltage detector to a ground voltage in response to the first voltage corresponding to a second logical value;
• and
• providing a second voltage from a first output of the first component to a second input of a second component of the device, the second voltage corresponding to the first logical value in response to a first voltage level of the first internal power supply satisfying a second voltage level, wherein the first logical value of the second voltage causes a second internal power supply of the second component to charge.

An apparatus comprising:

• means for controlling voltage droop at a first component of a device configured to:
• receive a first voltage at a first input of the first component, to charge a first internal power supply of the first component using an external power supply in response to the first voltage corresponding to a first logical value,
• receive a voltage at a voltage detector of the first component from the first internal power supply in response to the first voltage corresponding to the first logical value,
• couple an input of the voltage detector to a ground voltage in response to the first voltage corresponding to a second logical value, and
• to provide a second voltage corresponding to the first logical value from a first output of the first component to a second input of a second component of the device in response to a first voltage level of the first internal power supply satisfying a second voltage level;
• and
• means for controlling voltage droop at the second component configured to charge a second internal power supply of the second component using the external power supply in response to the second voltage corresponding to the first logical value.
