  • Sampled reference supply voltage supervisor
    Patent number: 8836377
    Abstract: A power supervisor circuit is provided. The circuit includes a first sample circuit that periodically samples a first reference voltage derived from a high output rail of a voltage source and generates a first sampled output voltage. The circuit includes second sample circuit that periodically samples a second reference voltage associated with a low output rail of the voltage source and generates a second sampled output voltage. A voltage supervisor in the circuit generates a trip point signal when a combination of the first and second sampled output voltage crosses a predetermined threshold indicating that the voltage source output voltage has fallen below a desired output voltage.

  • System and method for protecting IC components
    Patent number: 7359173
    Abstract: One embodiment provides a system for protecting at least one component in an integrated circuit (IC). The system includes a disconnect element that is electrically connected in series between a terminal of the IC and the at least one component. The disconnect element is configured to have a first state to permit an electrical signal to propagate from the terminal to the at least one component and a second state corresponding to a high impedance condition that electrically disconnects the terminal relative to the at least one component. A control system is configured to cause the disconnect element to transition from the first state to the second based on at least one predetermined activation condition.
