Engine control device

摘要

In order to provide an output voltage adjustment circuit (150) which is able to perform the screening of the semiconductor integrated circuit (111, 112) mounted as the bear chip status on the circuit board, and to plan reduction of the mounting area size and improvement of the electrical characteristic nature and reduction of the manufacturing cost by a simple constitution thereof, an engine control device (107) having a control device of the integrated circuit of the arithmetic processing unit for operating the control program is provided, and said engine control device (107) has an output voltage adjustment circuitry (150) to switch the rated voltage to screen the integrated circuit (112, 113), and said output voltage adjustment circuitry (150) has plural resistors (101, 102) between the output side power line of the rated voltage and the gland sides. <IMAGE>
