6. POWER REQUIREMENTS
6.1Supply Voltage
| Allowable voltage | 3.3V + 5% |
|
| Allowable noise/ripple | 70 mV |
|
(note | 1) When DC power is interrupted,+3.3V voltage drop must be greater than or equal to 0V. | ||
6.2 Power Consumption
| Average(note 1) |
| MK3006GAL／MK6006GAH／MK4006GAH |
Start (note 2) | 1.8 W Maximum |
Seek (note 3) | 1.1 W Typical |
Read / Write(note 4) | 1.1 W Typical |
Active idle (note 5 ) | 0.4 W Typical |
Low power idle (note 6) | 0.3 W Typical |
Stand- by (note 7) | 0.12 W Typical |
Sleep | 0.07 W Typical |
(note 1) Under normal condition ( 25oC, 101.3 kPa ( 1,013 mb ) ) and 3.3V + 0%.
(note 2) This is the maximum current value between power on to ready and the maximum value is the RMS(Root Mean Square) of 10 ms.Dose not include rush current.(more information Figure 1)
(note 3) The seek average current is specified based on three operations per 100 ms.
(note 4) The read/write current is specified based on three operations of 63 sector read/write per 100 ms.
(note 5) Motor is rotating at normal speed but none of Read, Write or Seek is executed.
(note 6) Motor is rotating at normal speed but heads are unloaded on the ramp.
(note 7) Motor is not rotating and heads are unloaded on the ramp.
