Latest Patents

Utani holds a patent for a drive circuit for semiconductor devices. This drive circuit is designed with an input terminal for receiving input signals and an output terminal that generates drive signals from these inputs. It also includes a control power supply terminal for receiving a control power supply voltage, an output terminal for output signals, and a reset terminal for receiving reset signals. The output signal is directed to the gate of a MOSFET. The circuit functions as a step-down chopper circuit, which reduces voltage through duty ratio control of the gate drive signal, thereby generating a control power supply voltage. Upon receiving a reset signal, the drive circuit ceases outputting the drive signal and adjusts the output signal to lower the control power supply voltage VCC. This innovation showcases Utani's ability to enhance semiconductor device functionality.
