Regulator & Reset function REGVCC Vref 2.5V 6 REGX KSB772 5 REGOX 4 RESX R1 8K 33uF R2 • • • • Vout 25K The external circuit is composed of the transistor, KSB772 and a capacitor, about 33uF. The capacitor is used as a ripple eliminator. The capacitor must have a good temperature characteristics. The regulator output voltage is decided as follows. V out = V ref × (1 + = 2 .5 × 8K 25 K R1 ) R 2 = 3.3V • When the voltage of the pin 4(RESX) is high, the regulator circuit operates normally. When the voltage of pin 4(RESX) is low, the regulator circuit is disabled. 9 FAN8047G3 3. TSD Function • When the chip temperature reaches to 160°C by abnormal condition, the TSD circuit is activated. • This makes the bias current of the output drivers shut down, and all the output drivers are on cut-off state. Therefore the chip temperature begins to decrease. • When the chip temperature falls to 140°C, the TSD circuit is deactivated and the output drivers start to operate normally. • The TSD function does not affect regulator operation. SVCC IREF Output driver bias R1 Q0 R2 Hysteresis Ihys R3 4. Notice • When REF1(pin1) or REF2(pin25) is lower than 0.7V, BTL output is off. • Under Voltage Protecton Function. ( If SVcc is lower than 3.8V, Chip is disable. Hysterisis is 0.2V) • Mute on BTL output voltage is as followed: - Mute ON BTL Output (CH1,2) = (PVcc1 ) / 2 - Mute ON BTL Output (CH3,4) = ((PVcc2-0.6) / 2 Each output to output and output to GND short should be kept away. 10 FAN8047G3 Typical performance characteristics Total circuit Icc(mA) Icc(mA) <Temp vs Icc1> <Vcc vs Icc1> 25 25 20 20 15 15 10 10 5 5 SV cc=12V PV cc2=12V PV cc1=5V Temp=25 OC 0 0 4.5 5.5 6.5 7.5 8.5 -35 -25 -15 -5 9.5 10.5 11.5 12.5 13.5 14.5 5 15 25 35 45 55 65 75 85 Temp(°C) Vcc(V) BTL Drive part Vom(V) Vom(V) <Vcc vs Vom2> <Vcc vs Vom1> 14 14 12 12 10 10 8 8 6 6 4 4 V in=0V RL=8 Ω 2 V in=0V RL=8 Ω 2 0 0 4 5 6 7 8 9 10 11 12 13 4 14 5 6 7 8 9 10 11 12 Vcc(V) 14 Vcc(V) Vom(V) Vom(V) 13 <Vcc vs Vom4> <Vcc vs Vom3> 14 14 12 12 10 10 8 8 6 6 4 4 V in=0V RL=24 Ω 2 Vin=0V RL=24Ω 2 0 0 4 5 6 7 8 9 10 11 12 13 14 Vcc(V) 4 5 6 7 8 9 10 11 12 13 14 Vcc(V) 11 FAN8047G3 Typical performance characteristics (Continued) Avf(dB) Avf(dB) <Vcc vs Avf2> <Vcc vs Avf1> 26 26 24 24 22 22 20 20 18 18 16 14 12 14 12 10 10 4 5 6 7 8 9 10 11 12 13 Temp=25 O C V in=0.3V Freg=1KHz RL=8 Ω 16 Temp=25 C V in=0.3V Freg=1KHz RL=8 Ω O 4 14 5 6 7 8 9 10 11 12 Avf(dB) Avf(dB) <Vcc vs Avf4> <Vcc vs Avf3> 26 26 24 24 22 22 20 20 18 18 16 16 Temp=25 O C V in=0.3V Freg=1KHz RL=24 Ω 14 12 5 6 7 8 9 10 11 12 13 Temp=25 O C V in=0.3V Freg=1KHz RL=24 Ω 14 12 10 10 4 14 5 6 7 8 9 10 11 12 Avf(dB) 14 Avf(dB) <Temp vs Avf1> <Temp vs Avf2> 24 24 22 22 20 20 18 18 16 SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=8 Ω 14 12 V in=+0.3V 10 V in=-0.3V 8 16 SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=8 Ω 14 12 V in=+0.3V 10 V in=-0.3V 8 -20 0 20 40 60 80 Temp(°C) 12 13 Vcc(V) Vcc(V) -40 14 Vcc(V) Vcc(V) 4 13 -40 -20 0 20 40 60 80 Temp(°C) FAN8047G3 Typical performance characteristics (Continued) Avf(dB) Avf(dB) <Temp vs Avf4> <Temp vs Avf3> 26 26 24 24 22 22 20 20 18 SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=24 Ω 16 14 V in=+0.3V 12 V in=-0.3V 10 -40 -20 0 20 40 60 80 18 SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=24 Ω 16 14 V in=+0.3V 12 V in=-0.3V 10 -40 -20 0 20 40 60 Temp(°C) 80 Temp(°C) Regulator part Temp vs V reg 3.45 3.40 3.38 3.35 3.33 3.30 3.28 3.25 3.23 3.20 3.4 Vreg(V) VREG(V) V CC vs V reg 3.35 3.3 3.25 3.2 4.5 6.5 8.5 10.5 V CC(V ) 12.5 3.15 -45 -20 5 30 55 80 Temp 13 14 25 24 23 22 4 MUTE3 IN5 REF2 IN4 IN3 SVCC 5 6 7 33uF FIN A KSB772 A Vout A 18 8 9 10 11 REGVCC 16 V 12 13 DO4+ 17 DO4- 19 DO3+ SW4 SW3 20 DO3- 21 GND MUTE4 FIN DO1+ 26 DO1- 27 A SW1 28 A DO2+ A DO2- A GND A MUTE12 A PVCC2 A PVCC1 A SW45 V A SW2 RESX 3 GND IN2 2 REGX IN1 1 REGOX REF1 FAN8047G3 Test circuits V 15 FAN8047G3 V 14 FAN8047G3 Typical application circuit DO1+ 14 16 DO4- DO1- 13 17 DO3+ DO2+ 12 18 DO3- DO2- 11 Focus Actuator Tracking Actuator GND 10 19 GND 20 MUTE4 MUTE12 21 PVCC2 PVCC1 9 5V 12V 0.1uF GND 7 23 IN3 REGX 6 24 IN4 REGOX 5 22 SVCC 0.1uF 8 FIN FIN 0.1uF FAN8047G3 12V REGVCC KSB772 Vout PVCC1 RESX 4 26 IN5 IN2 3 27 MUTE3 IN1 2 25 REF2 VREF1 MUTE3 SLED SPINDLE SW45 VREF2 LOADING MUTE4 FOCUS REF1 1 28 SW45 MICOM 33uF MUTE12 Spindle M Motor 15 DO4+ TRACKING Sled & Loading M Motor SERVO 15 FAN8047G3 Package dimension 28-SSOPH-375-SG2 Unit : mm 16 FAN8047G3 DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
