4. Tsd Monitor Function
PIN22 is TSD monitor pin which detects
the state of the TSD block and generates the TSD-monitor signal.
In normal state Q5 is turned on, so Q6 is turned off. on the otherhand, When the TSD block is is activated then Q5 is turned
off, so the voltage of pin22 is low.
Truth table is as follows

5. Focus, Tracking Actuator, Spindle, Sled Motor Drive Part
The voltage, Vref is the reference voltage given by the external bias voltage of the pin 43.
The input signal (Vin) through pins 1,4,7, 10 and 13 is amplified one time and then fed to the output stage.
(assume that input opamp was used as a buffer)
The total closed loop voltage gain is as follows
If you want to change the total closed loop voltage gain, you must use the input opamp as an amplifier
The output stage is the balanced transformerless (BTL) driver.
The bias voltage Vp is expressed as ;
