Figure 1.1 Current fluctuation (Typ.) at +5V when power is turned on

(5) Power on/off sequence
The voltage detector circuits (the MHR Series) monitor +5 V. The circuits do not
allow a write signal if either voltage is abnormal. These prevent data from being
destroyed and eliminates the need to be concerned with the power on/off
sequence.
