Latest Patents

Yoshimura's latest patents include a semiconductor device and a control system. The detection transistor in his control system flows a detection current to a current path when an output voltage generated in a load terminal exceeds a ground voltage. This system utilizes a current mirror circuit to transfer the detection current, and a detecting resistor element converts the mirror current into a detection voltage. A control transistor is activated when this detection voltage surpasses a predetermined value, allowing for precise control of the output transistor.

Another notable patent is a power control device designed to reliably disconnect the current path of a failed output transistor. This device includes output transistors, an output terminal, and bonding wires that connect the transistors to the terminal. It also features output transistor driving circuits and a failure detection circuit that identifies any failures in the output transistors. Upon detection of a failure, the driving circuits adjust the outputs to ensure a larger current flows through the bonding wires, enhancing the device's reliability.
