  • 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.
