关于接地检测比较器，请告知在BA8391G、BA2903、BA2901系列中，当电源电压(VCC)小于输入端子电压时流过输入端子的电流值。

接地检测比较器从VEE到输入端子具有静电保护二极管。在电源电压(VCC)小于输入端子电压时，只有二极管的反向漏电流流入输入端子，其参考值为在25℃下数10pA左右。

关于接地检测比较器，请告知在电源接通时序中，当电源电压(VCC)小于输入端子电压时的情况及注意点。

关于输入电压高于电源电压时的IC情况，如果一个输入端子的施加电压在同相输入范围内，则为与正常输入时相同的输出逻辑，如果两个输入端子的施加电压在同相输入范围外，则输出固定为Low。有关注意事项，由于接地检测比较器从输入端子到电源端子基本上都没有静电保护二极管，因此即使电源电压(VCC)小于输入端子电压，也不会有电流流入，只要输入电压不超过“绝对最大额定同相输入电压”，就不会发生劣化和损坏。但是，部分型号（BA10393F、BA10339F、BA10339FV）由于元件耐压方面的原因，有可能会发生劣化和损坏，因此要将“绝对最大额定同相输入电压”限制到VCC。
