4. TSD (THERMAL SHUTDOWN)
When the chip temperature rises up to about 175C(degree), the Q2 turns on and the output driver shuts down. When the chip
temperature falls off to about 150C(degree), then the Q2 turns off and the driver operates normally. TSD has the temperature
hysteresis of about 25C(degree).
-- The TSD circuit shuts down all the power drives(spindle and BTL power drives) excluding both CH1 and CH2 power
drives(actuator part).
5. ROTATIONAL DIRECTION DETECTION
1) The forward and the reverse rotations of the CD are detected by using the D-F/F and the truth table is shown in the above.
2) The rotational direction of the CD can be explained by the output waveform of the Hall sensors. Let the three outputs of
Hall sensors be H1, H2 and H3 respectively.
When the spindle rotates in reverse direction, the Hall sensor output waveform are shown in Fig.(a). Thus the phases
