본 개시는 ECU 보호회로, 전자 제어 유닛 및 조향 보조 시스템에 관한 것이다. 구체적으로, 본 개시에 따른 ECU 보호회로는 조향모터의 상전압이 미리 설정된 항복전압 이상인 경우, 역전류가 흐르도록 하는 제너 다이오드와, 역전류가 인가되면 턴온되어, 제1 전류가 흐르도록 하는 제1 스위치 및 제1 전류가 흐르면 턴온되어, 제2 전류가 흘러 배터리의 공급전압이 PCO 스위치로 도통되도록 하는 제2 스위치를 포함하며, PCO 스위치는, 공급전압이 인가되면 턴온되는 것을 특징으로 한다.

    The present disclosure relates to an ECU protection circuit, an electronic control unit and a steering assist system. Specifically, the ECU protection circuit according to the present disclosure includes: a Zener diode that allows a reverse current to flow when the phase voltage of a steering motor is more than a preset breakdown voltage; and a first switch that is turned on when the reverse current is applied and allows a first current to flow; and a second switch that is turned on when the first current flows and allows a second current to flow so that voltage supplied from a battery can be conducted to a PCO switch. The PCO switch is turned on when the supplied voltage is applied.
