MUTEM Pin #7 High Low Open Mute circuit Turn-off Turn-on Turn-on 7 Output driver bias * * * 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 175C, then the TSD (Thermal shutdown) circuit is activated and the output circuit is muted. 2. TSD (THERMAL SHUTDOWN) VREF BG Output driver bias R11 Q11 R12 * * * The VREF BG is the output voltage of the band-gap-referenced bias in 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. VBE = VREF BG x R12 / (R11 + R12) = 460mV When the chip temperature rises up to 175C, then the turn-on voltage of the Q11 would drop down to 460mV. (Hysteresis: 25C) Hence, the Q11 would turn on so the output circuit will be muted. 6 MIC-99D001 January 1999 CD-ROM PRODUCTS KA3010D 3. OP-AMP Op-amp is integrated in the IC for user's convenience.

DRIVER +I VREF (2.5V) 10k CH-I (3, 10, 19, 25 Pin) CH-GA (4, 9, 20, 24 Pin) 10k -I + - AMP Level shift + - Buffer Q1 -V M CH-O (1, 12, Q3 17, 27 Pin) CH-O (2, 11, 18, 26 Pin) +V Q2 + - Buffer Q4 * * * * * * * * * The voltage, VREF, 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 +I and -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 VREF, then the direction of the motor in forward direction. When the input voltage through the pin #3 is above the VREF, then the direction of the motor in reverse direction. If it is desired to change the gain, then the pin #4 can be used. The gain (AV) of the drive circuit is as follows. 4V IN A V = 20 log ----------- = 12 ( dB ) V IN MIC-99D001 January 1999 7 KA3010D CD-ROM PRODUCTS 5.
