20090116159 | OUTPUT VOLTAGE INDEPENDENT OVERVOLTAGE PROTECTION - One embodiment of the invention includes a power regulation system. The system comprises a power regulator configured to periodically generate a switch signal that regulates a current flow through an inductor to set a magnitude of an output voltage. The system further comprises an overvoltage protection circuit configured to monitor a peak voltage magnitude of the switch signal and to generate an overvoltage indication signal in response to the peak voltage magnitude of the switch signal exceeding a predetermined limit. | 05-07-2009 |

20130120890 | TRANSISTOR PROTECTION CIRCUIT - Provided is a transistor protection circuit capable of appropriately protecting a transistor even when a switching frequency is high. A transistor protection circuit according to an embodiment of the present invention is a transistor protection circuit for protecting a voltage-driven transistor that is switch-controlled by the application of a high-potential-side voltage or low-potential-side voltage of a power supply to a gate terminal of the transistor by a drive circuit. The transistor protection circuit has a power supply controller that gradually lowers the high-potential-side voltage of the power supply upon receiving a protection command for executing protection of the transistor. | 05-16-2013 |
20140347775 | BATTERY PROTECTION CIRCUIT - A battery protection circuit includes a control module, a first switch, and a loading module. The control module includes a second switch. A base terminal of the second switch is connected to a positive terminal of a battery, and an emitter terminal of the second switch is grounded. The first switch includes a gate terminal, a source terminal, and a drain terminal. The gate terminal is connected to the control module and further connected to a collector terminal of the second switch, and the source terminal is grounded. The drain terminal is connected to a first capacitor, and the first capacitor is grounded. The loading module is connected to the battery. When the loading module is abnormal, the gate terminal receives a control signal to switch off the first switch. | 11-27-2014 |
