CIRCUIT AND METHOD FOR MONITORING THE INTEGRITY OF A POWER SUPPLY |
摘要 |
Circuits and methods are provided herein for monitoring the integrity of a power supply, the circuits and methods providing additional resources/information for diagnosing a cause behind a reset signal, and in some cases, a reason behind a power failure. A first method described herein provides exemplary steps for monitoring a level of a power supply voltage supplied to one or more system components. A second method describes exemplary steps for monitoring an electrical connection between the power supply (or ground supply) and one or more supply pins. Each of the methods involves monitoring a state of one or more bits stored, e.g., within a status register. The methods may be used separately, or in conjunction with one another, for detecting the occurrence of a power abnormality. |
