Abstract
Example implementations relate to determining a failure event of a power supply. In some examples, an apparatus may comprise logic circuitry coupled to a signal line, the logic circuitry to receive a monitor signal via the signal line, where the monitor signal corresponds to an internal voltage of a power supply that is consumed wholly by the power supply, compare the monitor signal to a reference signal, and determine, based on the comparison, whether a failure event has occurred in the power supply.
Claims19
An apparatus, comprising:
- logic circuitry coupled to a signal line, the logic circuitry to:
- receive a monitor signal via the signal line, wherein the monitor signal corresponds to an internal voltage output from a first component of a power supply and consumed by a second component of the power supply;
- compare the monitor signal to a reference signal, which corresponds to a reference voltage, to generate a comparison result;
- and
- determine that a failure event has occurred in the power supply, when the comparison result indicates that the internal voltage is less than the reference voltage.
A controller, comprising:
- a memory;
- and
- logic circuitry coupled to a signal line, the logic circuitry to:
- receive a monitor signal including a monitor voltage via the signal line, wherein the monitor voltage comprises an internal voltage of a power supply, the internal voltage comprises a voltage generated by a bias converter of the power supply and received by another component of the power supply;
- compare the monitor voltage of the monitor signal to a threshold voltage of a reference signal;
- determine, based on the monitor voltage of the monitor signal being lower than the threshold voltage, that a failure event has occurred;
- and
- store the failure event in the memory.
A method, comprising:
- receiving, by a signal line of an apparatus, a monitor signal including a monitor voltage internal to a power supply, wherein the monitor voltage comprises a voltage generated by a component of the power supply and received by another component of the power supply;
- comparing, by logic circuitry of the apparatus coupled to the signal line, the monitor voltage of the monitor signal to a threshold voltage of a reference signal;
- determining, by the logic circuitry, a failure event in the power supply has occurred in response to the monitor voltage being lower than the threshold voltage;
- and
- storing, in memory of the apparatus, the failure event.
