Figure 1.2 Current fluctuation (Typ.) at +5 V when power is turned on
(6) Power on/off sequence
The voltage detector circuits (the MHT 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.
