Latest Patents

One of her latest patents is an electronic control device that provides a highly versatile and reliable power supply device (power supply ASIC). This device supports electronic devices with a wide range of drive currents while minimizing cost increases. The electronic control device includes a first power supply circuit that outputs a first voltage, a second power supply circuit that generates a second voltage from the first voltage, and a first MOSFET arranged independently of both power supply circuits. The second power supply circuit features a reference power supply that outputs a reference voltage, an amplifier that amplifies this reference voltage, and a voltage detection unit that detects the voltage value of the gate terminal of the first MOSFET. The switching unit connects an output from the amplifier to either the gate terminal of the first MOSFET or the gate terminal of the second MOSFET, controlled based on the voltage value detected.

Another significant patent is an electronic control device and diagnosis method that includes a timer operating during a key-off time period. This device is designed to diagnose whether the timer operates normally even during the key-off time period. It features a first power supply unit that is always supplied with battery voltage, including a first timer that measures the key-off time period, a diagnostic timer, and a first timer diagnosis unit that compares the timer values during the key-off time period.
