A monolithic integrated circuit device may include a supply voltage glitch detector for detecting improper supply voltage conditions. Advantageously, a detection threshold of the supply voltage glitch detector is adaptively set based on an operation mode of the device or a particular part of the device, which is internally known to the device based on certain inputs received by the device, such as commands, interrupts, control signals, etc. A method for detecting a glitch in supply voltage provided to the monolithic integrate circuit device having various modes of operation, comprises the steps of: operating the device in a first mode of operation selected from the operation modes; configuring, in response to operating in the first operation mode, a configurable detection threshold as one of a plurality of detection thresholds respectively associated with one or more of the operation modes, in accordance with the first operation mode; and monitoring the supply voltage for a glitch that violates the configurable detection threshold as configured in the configurable detection threshold configuring step. |
