Abstract
Illustrative circuits and methods are provided. Circuitry is configured to detect a decrease in a monitored voltage at greater than a threshold rate. A fuse is deliberately blown in response to the detection. Power control circuitry is disabled and prevented from resuming normal operations by way of control signaling. The blown fuse ensures that at least one control signal is maintained until the blown fuse is replaced by service personnel. Shunt circuitry optionally discharges storage capacitors of the power control circuitry. Sensitive electronic components are protected against over-voltage or overcurrent damage in accordance with the present teachings.
