Device Overview
(3) Current Requirements and Power Dissipation
Table 1.3 lists the current and power dissipation.

*1 Current at starting spindle motor.
*2 Power requirements reflect nominal values for +5V power.
*3 At 30% disk accessing.
(4) Current fluctuation (Typ.) at +5V when power is turned on
Figure 1.1 Current fluctuation (Typ.) at +5V when power is turned on
(5) Power on/off sequence
The voltage detector circuit monitors +5 V. The circuit does not allow a write signal if either voltage is abnormal. This prevents data from being destroyed and eliminates the need to be concerned with the power on/off sequence.
