On the other hand, when the mute pin is high , the TR Q1 is turned off and the bias circuit is disabled. It will make all the circuit blocks except CH1 off, so low power quiescent state can be established. • Truth table is as follows Pin 23 High Low FAN8026 Mute-On Mute-Off 23 Bias Current CH2,3,4,5 Q1 2. TSD Function • When the chip temperature reaches to 175°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 155°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 REF(pin23) 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(CH2,3,4,5) = VM / 2 - Mute on BTL output CH1 = ((PVcc2-0.6) / 2 • Each output to output and output to GND short should be kept away. 10 FAN8026G3 Typical Application Circuit Spindl e Motor 1 5 DO2- DO3- 1 4 M 1 6 1 7 DO2+ DO1DO3+ VM1 1 3 1 2 M S led Motor Loadin g Motor M 1 8 DO1+ IN1 1 1 5V 8V 2 0 OUT3 FAN8026G3 1 9 SVCC OUT2 1 0 IN2 9 2 1 IN3 GND 8 FIN 2 2 REF OUT4 IN4 2 3 2 4 MUTE VM2 OUT5 5V Focus Actuat or 2 5 DO4+ IN5 2 6 DO4- OPOUT Trackin g Actuato r 2 7 DO5+ DO5- OPIN- 2 8 OPIN+ VREF FIN 7 6 5 4 3 2 1 7 TRACKING SERVO LOADING FOCUS MUTE SLED SPINDLE 11 FAN8026G3 Test Circuits SW3 SW5 SW4 A V A A A A A V 28 DO527 DO5+ 26 DO4- V 25 DO4+ 24 VM2 23 MUTE 22 REF FIN 21 IN3 20 OUT3 19 SVCC 18 DO1+ 17 DO116 DO2+ DO3+ 13 SW2 V 15 DO2V DO314 11 IN1 A VM1 12 SW1 A FAN8026G3 OPIN+ OPIN- OPOUT OUT5 OUT4 IN4 1 IN+ 2 IN- 3 OUT 4 5 6 7 FIN 8 IN2 9 10 OP-AMP A A A A A IN+ SW6 v OP-AMP INSW7 OUT SW8 SW9 12 OUT4 A IN5 GND FAN8026G3 Package Dimension 28-SSOPH-375-SG2 13 FAN8026G3 DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
