The capacitor is used as a ripple eliminator. The capacitor must have a good temperature characteristics. The regulator output voltage is decided as follows. out =V ref × (1 + 8K 25 K R1 ) R2 = 3.3V = 2 .5 × • 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.

( 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) 25 20 15 10 5 Temp=25 OC 0 4.5 5.5 6.5 7.5 8.5 9.5 10.5 11.5 12.5 13.5 14.5 0 -35 -25 -15 -5 5 15 25 20 15 10 5 SV cc=12V PV cc2=12V PV cc1=5V 25 35 45 55 65 75 85 Icc(mA) Vcc(V) Temp(°C) BTL Drive part Vom(V) Vom(V) 14 12 10 8 6 4 2 0 4 5 6 7 8 9 10 11 12 13 14 V in=0V RL=8 Ω 14 12 10 8 6 4 2 0 4 5 6 V in=0V RL=8 Ω 7 8 9 10 11 12 13 14 Vcc(V) Vom(V) Vom(V) Vcc(V) 14 12 10 8 6 4 2 0 4 5 6 7 8 9 10 11 12 13 14 V in=0V RL=24 Ω 14 12 10 8 6 4 2 0 4 5 6 7 Vin=0V RL=24Ω 8 9 10 11 12 13 14 Vcc(V) Vcc(V) 11 FAN8047G3 Typical performance characteristics (Continued) Avf(dB) Avf(dB) 26 24 22 20 18 16 14 12 10 4 5 6 7 8 9 10 11 12 13 14 Temp=25 C V in=0.3V Freg=1KHz RL=8 Ω O 26 24 22 20 18 16 14 12 10 4 5 6 7 8 9 10 11 12 13 14 Temp=25 O C V in=0.3V Freg=1KHz RL=8 Ω Vcc(V) Avf(dB) Avf(dB) Vcc(V) 26 24 22 20 18 16 14 12 10 4 5 6 7 8 9 10 11 12 13 14 Temp=25 O C V in=0.3V Freg=1KHz RL=24 Ω 26 24 22 20 18 16 14 12 10 4 5 6 7 Temp=25 O C V in=0.3V Freg=1KHz RL=24 Ω 8 9 10 11 12 13 14 Vcc(V) Avf(dB) Avf(dB) Vcc(V) 24 22 20 18 16 14 12 10 8 -40 -20 0 20 40 60 80 V in=+0.3V V in=-0.3V SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=8 Ω 24 22 20 18 16 14 12 10 8 -40 -20 V in=+0.3V V in=-0.3V 0 20 40 SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=8 Ω 60 80 Temp(°C) Temp(°C) 12 FAN8047G3 Typical performance characteristics (Continued) Avf(dB) Avf(dB) 26 24 22 20 18 16 14 12 10 -40 -20 0 20 40 60 80 V in=+0.3V V in=-0.3V SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=24 Ω 26 24 22 20 18 16 14 12 10 -40 -20 V in=+0.3V V in=-0.3V 0 20 40 SV cc=12V PV cc1=5V PV cc2=12V Freq=1KHz RL=24 Ω 60 80 Temp(°C) Temp(°C) Regulator part V CC vs V reg 3.40 3.38 3.35 3.33 3.30 3.28 3.25 3.23 3.20 4.5 6.5 8.5 10.5 12.5 V CC(V ) 3.45 3.4 Vreg(V) 3.35 3.3 3.25 3.2 3.15 -45 -20 5 30 Temp 55 80 Temp vs V reg VREG(V) 13 14 A REF1 A 27 IN1 MUTE3 A IN2 IN5 A REF2 A IN4 24 IN3 23 RESX 25 SW45 28 1 A 2 26 3 4 5 REGX 22 GND SVCC 6 7 REGVCC REGOX A A KSB772 FAN8047G3 Test circuits FAN8047G3 33uF Vout FIN 8 SW2 11 DO2DO2+ DO1V DO1+ 14 V SW1 A 9 MUTE12 GND A 10 12 13 PVCC1 FIN PVCC2 A 21 20 MUTE4 GND DO3DO3+ DO4DO4+ 19 SW3 18 V 17 SW4 16 V 15 A FAN8047G3 Typical application circuit 15 DO4+ Sled & Loading M Motor 16 DO417 DO3+ Spindle M Motor 18 DO319 GND 20 MUTE4 12V 21 PVCC2 0.1uF FIN DO1+ 14 DO1- 13 DO2+ 12 DO2- 11 GND 10 MUTE12 PVCC1 9 5V 8 0.1uF FIN Tracking Actuator Focus Actuator 12V 0.1uF 22 SVCC 23 IN3 24 IN4 25 REF2 26 IN5 27 MUTE3 28 SW45 FAN8047G3 GND REGX REGOX RESX IN2 IN1 7 6 5 PVCC1 4 3 2 REGVCC KSB772 Vout 33uF REF1 1 MICOM SERVO TRACKING LOADING SPINDLE MUTE12 SW45 MUTE4 VREF1 MUTE3 FOCUS VREF2 SLED 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.
