| 20120026633 | DECREASING VOLTAGE DETECTION WITH CONTROL SIGNALING - 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. | 2012-02-02 |
| 20120026634 | VOLTAGE DETECTION CIRCUIT DEVICE - A voltage detection circuit device acquires a predetermined compare voltage through a voltage acquisition circuit by a power source of a power supply circuit. After a voltage step-down circuit steps down a voltage, the compare voltage acts as a voltage reference, and high and low potential comparators of the compare circuit compare the voltage of a power source of the power supply circuit. If the voltage of the power source of the power supply circuit falls within a normal range, the high potential comparator will output a high potential signal, while the low potential comparator will output a low potential signal. After an electronic circuit supplied with electric power receives the electric potential signals, the electronic circuit starts its operation. By determining whether or not the voltage of the power supply falls within the normal range, damages to the electronic circuit by abnormal power supply can be prevented. | 2012-02-02 |
