*1: If the power supply voltage fluctuates within the time less than the detection delay time (t
d
), there is a
possibility that the low voltage detection will occur or stop after the power supply voltage passes the
detection range.
*2: In order to perform the low voltage detection at the detection voltage (V
DLX
), be sure to suppress fluctuation
of the power supply voltage within the limits of the change ration of power supply voltage.
