PWM IC METHOD FOR CONTROLLING PEAK TIME DURATION OF SUPPLY CURRENT OF PULSE WIDTH MODULATION SOLENOID DRIVE INTEGRATED CIRCUIT

摘要

A method of controlling the supply current peak duration of a PWM solenoid driver IC according to an embodiment of the present invention is characterized in that the TCU has a maximum peak duration Max Max allowed to the PWM solenoid driver IC, Comparing the mutual magnitudes of the calculated peak calculated by the TCU and the on-duty duration commanded by the TCU to the PWM solenoid driving IC based on the voltage, And the TCU instructs an ISR (Interrupt Service Routine) including information on a period and a duty to the PWM solenoid driving IC according to the comparison result to calculate a peak duration of a current supplied by the PWM solenoid driving IC .
