본 발명은 배터리 관리 장치용 충격 감지 회로에 관한 것으로, 차량으로부터 출력된 충격신호가 배터리 관리 장치에 입력되면, 지정된 기준전압(Vref)을 생성하는 기준전압생성부; 및 상기 기준전압생성부에서 생성되는 기준전압(Vref)과 충격신호를 비교하여, 충격신호가 지정된 최소 유지시간 이상이면서 지정된 기준전압(Vref) 이상이면 충격감지신호(Vo_com)를 출력하는 비교기를 포함하는 것을 특징으로 한다.

    A crash detection circuit of a battery management unit (BMU), includes a reference voltage generator configured to generate a reference voltage in response to a crash signal output from a vehicle being input to the BMU; and a comparator configured to compare the reference voltage generated from the reference voltage generator with a processed crashed signal corresponding to the crash signal and to output a crash detection signal in response to the processed crash signal having a duration greater than or equal to a minimum retention time and at a voltage greater than or equal to the reference voltage.
