FUJITSU DISK DRIVES MHM215OAT - Manual (Page 28)

1.4 Environmental Specifications
C141-E104-02EN 1-7
Figure 1.1 Current fluctuation (Typ.) at +5V when power is turned on
(5) Power on/off sequence
The voltage detector circuits (the MHL Series and MHM 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.
