Description



Features:

1) Low vibration/low noise by 180° PWM driving
2) Charge-pump circuit is not necessary for output due to complement power MOSFET.
3) Low power consumption due to low ON resistance Spindle driver output: 0.5W (Typ.) Slide/Focus/Tracking driver output: 1.2W (Typ.)
4) 1 phase/3 phase FG output can be switched by FG switching pin.
5) VQFP48C contributes to make the set smaller and thinner.
