1. A system, comprising:
- at least one power supervisor coupled to a power supply voltage and including a processing element configured by instructions stored in a memory to assert at least one output signal in response to at least one comparator output, at least one comparator having a first input coupled to a programmable threshold voltage and a second input coupled to a reference voltage, and configured to provide the at least one comparator output, and at least one programmable voltage divider coupled to the first input of the comparator and configured to vary a voltage divided output in response to the processing element.

Abstract
A system can include at least one power supervisor coupled to a power supply voltage and including a processing element configured by instructions stored in a memory to assert at least one output signal in response to at least one comparator output, at least one comparator having a first input coupled to the power supply voltage and a second input coupled to a reference voltage, and configured to provide one comparator output, and at least one programmable voltage divider coupled to one input of the comparator and configured to vary a voltage divided output in response to the processing element.

10. A method, comprising:
-
dynamically asserting at least one output signal with a processing element in response to at least a comparison between a reference voltage and a threshold voltage programmable by the processing element, and a state of a system containing the processing element, wherein the threshold voltage is programmed into a memory by the processing element; and applying the output signal to circuitry coupled to a power supply voltage. - View Dependent Claims (11, 12, 13, 14, 15)
