6. POWER REQUIREMENTS
6.1 Supply Voltage
Allowable voltage 3.3V + 5%
Allowable noise/ripple 70 mV p-p or less
(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.
