fan8001d 7 application information 1. mute ? when the mute pin #7 is open or the voltage of the mute pin #7 is below 0.5v, the mute circuit is activated so that the output circuit will be muted. ? when the voltage of the mute pin is above 2v, the mute circuit is stopped and the output circuit is operated normally. ? if the chip temperature rises above 175 c, then the tsd (thermal shutdown) circuit is activated and the output circuit is muted. 2. tsd (thermal shutdown) ?the v ref bg is the output voltage of the band-gap-referenced biasing circuit and acts as the input voltage of the tsd circuit. ? the base-emitter voltage of the tr, q11 is designed to turn-on at below voltage. v be = v ref bg r12 / (r11+r12) = 400mv ? when the chip temperature rises up to 175 c, then the turn-on voltage of the q11 would drop down to 400mv. hence, the q11 would turn on so the output circuit will be muted. pin #7 mute circuit high turn-off low turn-on 7 output driver bias v ref bg r11 r12 q11 output driver bias
fan8001d 8 3. regulator ?the v ref bg is the output voltage of the band-gap-referenced biasing circuit and is the reference voltage of the regulator. ? the external circuit is composed of the transistor, ksb772 and a capacitor, 100 m f, and the capacitor is used as a ripple filter and should have a good temperature characteristics. ? the output voltage, v out is determined as follows. v out = v ref bg 2 = 2.5 2 = 5v (r2 = r3) r2 = r3 4. loading motor driver ? the input voltages of (5v and 0v) or (0v and 5v) pairs are applied to the input pin #9 and #14 respectively. ? when the input voltages are applied to the input pin #9 and #14, then the output of the comparator is decided depends on the input voltage status. ? as shown in the above diagram, the difference d v, [ v ref1 + (i r)] - [v ref1 -(i r)], is applied to the both terminals of the motor. the direction of the motor is decided by the voltage difference, + d v and -d v. ? the output characteristics is as follows, - if pin # 9=5v and #14=0v, then pin # 15=+ d v and #16= -d v, hence the motor turn in forward direction. - if pin # 9=0v and #14=5v, then pin # 15= -d v and #16=+ d v, hence the motor turn in reverse direction. - if pin # 9=5v and #14=5v, then d v=0v, hence the motor stop. - if pin # 9=0v and #14=0v, then d v=0v, hence the motor stop. ? when the rotation speed control of the loading motor is desired, refer to the follows. 5 6 + - i vref bg d1 r1 d2 ksb772 v out (5v) ce 100 m f + r2 r3 + - + - buffer buffer q1 q3 m q2 q4 -d v+ d v 9 15 + - 14 20 16 + d v -d v v ref1 comp r i i r v ref1
fan8001d 9 5. loading motor speed control ? if the torque of the loading motor is too low with the pin #20 open, then use it as the above diagram. ? the desired torque could be obtained by selecting the appropriate resistor r as shown in the left diagram. ? if it is necessary, the zener diode can be used as in the right diagram. ? the maximum torque is obtained when the applied voltage at pin #20 is about 6.8v (at v cc =8v). 6. driver (except for loading motor driver) ? the voltage, v ref , is the reference voltage given by the bias voltage of the pin #23. ? the input signal through the pin #3 is amplified by 10k/10k times and then fed to the level shift. ? the level shift produces the current due to the difference between the input signal and the arbitrary reference signal. the current produced as + d i and -d i is fed into the driver buffer. ? driver buffer operates the power tr of the output stage according to the state of the input signal. ? the output stage is the btl driver and the motor is rotating in forward direction by operating tr q1 and tr q4. on the other hand, if tr q2 and tr q3 is operating, the motor is rotating in reverse direction. ? when the input voltage through the pin #3 is below the v ref , the motor rotates forward direction. ? when the input voltage through the pin #3 is above the v ref , the motor rotates reverse direction. ? if it is desired to change the gain, then the pin #4 or #24 can be used. 20 20 v cc (8v) 4v 50k r v cc d v cc r 50k 50k 50k 4v v cc (8v) + - + - + - 10k 100k vref (2.5v) 10k amp level shift -d i + d i buffer buffer q1 q3 m q2 q4 -d v+ d v 25 19 10 3 24 4 11 1 17 27 12 2 18 26
fan8001d 10 7. when the bias voltage of the pin #23 is below 1.4v, then the output circuit will be muted. hence for the normal operation, the bias voltage should be used in 1.6v~6.5v. 8. connect a by-pass capacitor, 0.1 m f between the supply voltage source. 9. radiation fin is connecting to the internal gnd of the package. connect the fin to the external gnd. 22 21 104 v cc2 v cc1
