Abstract

본 발명은 구동전압 검출회로에 관한 것으로서 호스트로부터 입력되는 구동신호의 레벨에 따라 제1 및 제2전압 동작셀과 이 제1 및 제2전압 동작셀을 선택하는 스위치와, 구동전압단에 상기 구동신호와 동일한 레벨의 구동전압이 인가되어 노드에서 제1기준전압을 발생하는 제1기준전압발생부와, 구동전압단에 상기 구동신호와 동일한 레벨의 구동전압이 인가되어 노드에서 제2기준전압을 발생하는 제2기준전압발생부와, 상기 제1 및 제2기준전압을 비교하여 제1 또는 제2통로를 활성화시켜 ‘하이’또는 ‘로우’ 상태의 셀선택신호를 상기 스위치로 출력하는 비교부를 포함한다. 따라서, 구동전압의 레벨에 따라 해당되는 동작셀을 칩의 외부에서 기계적으로 선택하지 않고 회로적으로 선택할 수 있다.The present invention relates to a driving voltage detecting circuit, and more particularly, to a driving voltage detecting circuit comprising switches for selecting first and second voltage operating cells and first and second voltage operating cells according to a level of a driving signal input from a host, A first reference voltage generator for generating a first reference voltage at a node to which a driving voltage of the same level as the signal is applied and a second reference voltage generator for applying a driving voltage of the same level as the driving signal to the driving voltage terminal, And a comparator for comparing the first and second reference voltages and activating the first or second channel to output a cell selection signal in a 'high' or 'low' state to the switch . Therefore, depending on the level of the driving voltage, the corresponding operating cell can be selected in a circuit manner without mechanically selecting the outside of the chip.
