An integrated circuit includes a comparison circuit that is arranged to trip based on a power supply signal reaching a trip point. The integrated circuit also includes an analog-to-digital converter that is arranged to convert the power supply signal into a digital signal. The integrated circuit also includes a storage component that stores a digital value associated with the digital signal, and provides the power supply value at an output pin of the integrated circuit. The integrated circuit includes a latch that is coupled between the analog-to-digital converter and the storage component. The latch is arranged to open when the comparison circuit trips, such that, when the comparison circuit trips, the storage component continues to store a digital value such that the digital value corresponds to the voltage associated with the power supply signal when the comparison circuit tripped. | 2015-02-26 |
