Abstract
In some embodiments, a power supply slew rate detector may include a filter circuit having a capacitive element operably coupled to a power supply output provided to a flash memory circuit and a resistive element operably coupled to the capacitive element and to ground, and a Schmitt trigger including an input operably coupled to a node between the capacitive element and the resistive element, the Schmitt trigger further including an output configured to indicate a slew rate of the power supply output.
