Latest Patents

Okumura holds a patent for a switching device control circuit. This invention offers a solution that can accurately estimate the temperature of a power device, enabling thermal shutdown without the need for additional terminals. The control circuit features an output unit that regulates the operating current flowing through an Insulated Gate Bipolar Transistor (IGBT) based on an input signal. It also includes a temperature detection unit that outputs a detection signal when the temperature exceeds a second preset threshold, which is set in relation to the first preset temperature of the IGBT after it begins operation. The output control unit then manages the output unit to turn off the IGBT in response to this detection signal.
