Abstract
An apparatus may include first circuitry coupled to one or more platform components, the first circuitry operative to receive an unfiltered input voltage signal, compare a first voltage level of the unfiltered input voltage signal to a first reference voltage level, and generate a control signal operative to lower operation power of one or more of the one or more platform components when the first voltage level is less than the first reference voltage level.
Claims23
An apparatus, comprising:
- first circuitry coupled to one or more platform components, the first circuitry operative to:
- receive an unfiltered input voltage signal;
- compare a first voltage level of the unfiltered input voltage signal to a first reference voltage level;
- and
- generate a control signal operative to lower operation power of one or more of the one or more platform components when the first voltage level is less than the first reference voltage level;
- and
- second circuitry coupled to one or more platform components, the second circuitry operative to:
- filter the input voltage signal;
- compare a second voltage level of the filtered input voltage signal to a second reference voltage level that is less than the first voltage level;
- and
- disable the control signal when the second voltage level is below a second reference voltage.
A method, comprising:
- receiving an unfiltered input voltage signal;
- comparing a first voltage level of the unfiltered input voltage signal to a first reference voltage level;
- and
- generating a control signal to lower operation power of one or more platform components when the first voltage level is below the first reference voltage level;
- filtering the input voltage signal;
- comparing a second voltage level of the filtered input voltage signal to a second reference voltage level that is less than the first reference voltage level;
- and
- disabling the control signal when the second voltage level is below a second reference voltage.
An apparatus, comprising:
