■ APPLICATION SUMMARY - Reference & CH1 ~CH4 mute When you want to control output bias current of the S30011, u se pin #23 as follows - Mute When you want to control output bias current of the S30011, you can also use pin#7 as follows

■APPLICATION SUMMARY(Continued) - Thermal Shutdown The S30011 has a thermal protection against the abnormal ope ration, 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.

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(21K) converts current into voltage with the DC offset of Pref. The power amp has unity gain. So the total differential voltage gain of the S30011 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 amp. 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 INPUT OUTPUT FWD(PIN9) REV(PIN14) DO5+(PIN15) DO5-(PIN16) STATUS High High Vp Vp Brake High Low High Low Forward Low High Low High Reverse Low Low Vp Vp Brake

■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 sho wn 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 S30011 has a temperature independent voltage source internally. So in the figure 7, the reference vo ltage (2.5V) is generated by the internal circuit (bandgab reference),
