KSI-8030-003 6 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. KSI-8030-003 7 S3001 ■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 FWD(PIN9) High High Low Low REV(PIN14) High Low High Low DO5+(PIN15) Vp High Low Vp OUTPUT DO5-(PIN16) Vp Low High Vp STATUS Brake Forward Reverse Brake KSI-8030-003 8 S3001 ■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), × KSI-8030-003 9 S3001 TEST CIRCUIT KSI-8030-003 10 S3001 TIPICAL APPLICATION CIRCUIT KSI-8030-003 11 S3001 INTERNAL CIRCUIT Pin no Pin name Internal circuit 1,2, 11,12, 15,16 17,18 26,27 DO1DO1+ DO2+ DO2DO5+ DO5DO3DO3+ DO5+ DO5- 3, 4, 10, 19, 23, 24, 25, IN1 IN1A IN2 IN3 REF IN4A IN4 KSI-8030-003 12 S3001 INTERNAL CIRCUIT(Continued) Pin no Pin name Internal circuit 6 REO 7 MUTE 9,14 FWD REV KSI-8030-003 13 S3001 INTERNAL CIRCUIT(Continued) Pin no Pin name Internal circuit 20 CTL KSI-8030-003 14 S3001 Electrical Characteristic Curves Fig. 1.
