■ APPLICATION SUMMARY
- Reference & all mute
When you Want to control output bias current of the S3001, use pin #23 as follows
- Mute
When you want to control output bias current of the S3001, you can also use pin#7 as follows

■APPLICATION SUMMARY(Continued)
- Thermal Shutdown
The S3001 has a thermal protection against the abnormal operation, and the detailed operation of the TSD circuit is as follows
- BTL drive part (Focus, Tracking, Spindle, Sled drive park)
BTL drive park is composed of V-I converter, level shifter and output power amp.
KSI-8030-003

S3001
The level shift changes the direction of the current(lconv) as the same amount, and then supply it to the power AMP.
The resistor Ra(10.6K) converts current into voltage with the DC offset of Pref.

The power amp has unity gain.
So the total differential voltage gain of the S3001 is as follows.

×
×
If you want to reduce the total gain of the BTL drive part, use additional series resistor into the input pin(pin#3, 10, 19, 25)
You can also increase or decrease the voltage gain of the CH1, CH4 using adjustable pin(pin#4, pin24) by inserting an external
series resistor.

■APPLICATION SUMMARY(Continued)
- Tray motor drive part
CH5 is a forward-reverse control DC motor driver and it is composed of logic control part, level shifter, and output power
The forward and reverse rotation is controlled by pin9(fwd), pin14(rev) and the amplitude of the output voltage is controlled
by pin20(CTL).
The output status due to the input conditions are as follows

■APPLICATION SUMMARY(Continued)
- Tray motor speed control
The amplitude of the output voltage is controlled by pin20(CTL).
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
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),
