| 20090128106 | Power supply controller and semiconductor device - A voltage-dividing circuit | 05-21-2009 |
| 20090167272 | Power Supply Controller - A first current corresponding to the drain-to-source voltage of a power MOSFET can pass through an FET; and a second current corresponding to a constant voltage can pass through an FET; a third current corresponding to the difference determined by subtracting the first current from the second current can pass into threshold setting resistors from the connecting point between FETs. Consequently, divided voltages at the connecting points between the threshold setting resistors varies directly with a voltage corresponding to the difference determined by subtracting the drain-to-source voltage of the power MOSFET from the constant voltage. | 07-02-2009 |
| 20100134939 | POWER SUPPLY CONTOLLER - A second forcing shutoff operation is performed for a power MOSFET | 06-03-2010 |
| 20110193414 | ELECTRIC POWER SUPPLY CONTROL CIRCUIT - An electric power supply control circuit includes a bypass circuit connected in parallel with a semiconductor switch. Upon a control circuit being in an inactive state while a load being in a non-electrifying state or in a standby state, the bypass circuit connects a power source to the load. The bypass circuit includes a electrifying decision circuit that generates an activation signal for activating the control circuit in accordance with the load being put in an operation state. The electrifying decision circuit supplies the activation signal to the control circuit so as to turn on the semiconductor switch and allow electric power supply to the load through an electrifying line. | 08-11-2011 |
