摘要： An apparatus for controlling an electric current of a solenoid in a vehicle is provided to control a solenoid current regardless of a temperature change by applying a constant current to the solenoid without using a high performance MCU(Micro Control Unit). An apparatus for controlling an electric current of a solenoid in a vehicle includes an electronic control unit, a digital/analog converter(110), a solenoid driver(120), a solenoid voltage detector(130), a comparator(140), and a current controller(150). The electronic control unit outputs a target voltage so that a constant current flows to a solenoid coil of the solenoid driver. The digital/analog converter converts the target voltage from the electronic control unit into an analog target voltage. The solenoid voltage detector detects a voltage across a resistor of the solenoid driver supplied from a battery. The comparator compares an output voltage of the solenoid voltage detector with the target voltage from the electronic control unit, and outputs a comparison result signal. The current controller allows a constant current to flow through a solenoid coil or cuts off the current flowing through the solenoid coil.

摘要： A level shifting and scaling circuit is provided to enable a microcomputer to recognize a change of a sensor output value by scaling and inputting a level of a resolution output to the microcomputer. A level shifting and scaling circuit includes a voltage follower, an offset remover unit, and a level shifting unit. The voltage follower scales a current value from an output of a current measurement sensor. The offset remover unit removes the offset value of the current measurement sensor from the output of the voltage follower. The level shifting unit shifts a level of the signal of which an offset value is removed. The voltage follower has an operational amplifier which receives an output of the current measurement sensor through a non-inverse terminal and feedbacks an output signal to an inverse terminal. The offset remover unit is composed of a zener diode coupled to the output terminal of the operational amplifier.
