SEMICONDUCTOR DEVICE, IN-VEHICLE VALVE SYSTEM AND SOLENOID DRIVER |
摘要 |
An output driving circuit outputs an output current to a solenoid incorporated in a vehicle through an output terminal. A detection resistor connected between the output terminal and the output driving circuit. An amplification unit configured to output an analog detection signal generated by amplifying a voltage between both ends of the detection resistor. A current generation circuit configured to output a reference current. A reference resistor connected between the current generation circuit and a ground and configured to output a reference voltage according to the reference current. An A/D converter configured to convert the analog detection signal into a digital detection signal using the reference voltage as a reference. A control circuit configured to control the output current output from the output driving circuit according to the digital detection signal. |
