• Manufacturer Part Number: S3001
• Description: 15 V, 5-ch motor drive IC
• Manufacturer: AUK Corp.

■APPLICATION SUMMARY(Continued)
- Tray motor speed control
Normally, the differential output voltage is 3.1V when the pin20(CTL) is open.
If you want to control differential output voltage of the tray drive part, insert external resistor R and zener diode ZD as shown
in figure 6.
Zener diode ZD is only needed when you want to obtain a precision output voltage, In other case you only insert an external
resistor R.
- Regulator part
The amplitude of the output voltage is controlled by pin20(CTL).
S3001 has a temperature independent voltage source internally.
So in the figure 7, the reference voltage (2.5V) is generated by the internal circuit (bandgab reference),
