TSD Function • When the chip temperature reaches to 167°C by abnormal condition, the TSD circuit is activated • During TSD Function is activated, OP-AMP Output (pin 6) remains below 0.5V. (TSD monitoring function). • 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 63°C, the TSD circuit is deactivated and the output drivers start to operate normally. SVCC IREF R1 Q0 R2 Hysteresis Ihys R3 Output driver bias 3. Notice • If 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. 9 FAN8045G3 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) 10 FAN8045G3 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) 11 FAN8045G3 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) OP-AMP Part Isink(mA) Isou(mA) 60 50 40 30 20 10 0 4 5 6 7 8 9 10 11 12 13 14 4 2 0 4 5 6 7 10 8 6 8 9 10 11 12 13 14 Vcc(V) Isink(mA) Isou(mA) Vcc(V) 60 50 40 6 10 8 30 20 10 0 -40 -20 0 20 40 60 80 4 2 0 -40 -20 0 20 40 60 80 Vcc(V) Vcc(V) 12 FAN8045G3 Test Circuits SW3 A A A A A A A A A V 28 SW45 27 MUTE3 26 IN5 25 REF2 24 IN4 23 IN3 22 SVCC FIN 21 PVCC2 20 MUTE4 19 GND 18 DO317 DO3+ 16 DO4DO113 SW4 V 15 DO4+ V SW1 DO1+ 14 DO211 V DO2+ 12 FAN8045G3 REF1 MUTE12 9 A OPOUT PVCC1 OPIN+ OPIN- GND 1 2 3 4 IN+ 5 6 7 FIN 8 10 IN- OUT SW2 A A OP-AMP IN+ SW6 v OP-AMP INSW7 OUT SW8 SW9 GND IN1 IN2 13 FAN8045G3 Typical Application Circuit 15 DO4+ Sled & Loading M Motor 16 DO417 DO3+ Spindle Motor M 18 DO319 GND 20 MUTE4 12V 21 PVCC2 0.1uF FIN DO1+ DO1DO2+ DO2GND MUTE12 PVCC1 14 Focus Actuator 13 12 Tracking Actuator 11 10 9 5V 8 0.1uF FIN 12V 0.1uF 22 SVCC 23 IN3 24 IN4 25 REF2 26 IN5 27 MUTE3 FAN8045G3 GND OPOUT OPINOPIN+ IN2 IN1 REF1 7 6 5 4 3 2 1 28 SW45 MICOM SERVO 14 TRACKING LOADING SPINDLE MUTE12 MUTE4 SW45 MUTE3 FOCUS VREF2 VREF1 SLED FAN8045G3 Package Dimension 28-SSOPH-375-SG2 15 FAN8045G3 DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
