VP
A voltage, VREF is the reference voltage driven by the external bias voltage on pin#23. The input signal(Vin) on pin#12 and #20 is uplifted by 10K/10K times and then fed to the level shift. The level shift provides a current as +I and -I due to the difference between the input signal and the arbitrary reference signal. The current can be fed into the driver Amp, so it drives the power TR on the output stage. The output can be shown 2 times as much as the input signal. (gain = 1 + 10K/10K).
VV IN = V REF + VI = ---------10K 10K DO + = V P + I * 10K * 1 + ---------- = V P + 2V 10K 10K DO - = V P - I * 10K * 1 + ---------- = V P - 2V 10K V OUT = ( DO+ ) - ( DO- ) = 4V V OUT GAIN = 20 log ------------- = 12dB V
Pin#3 or #25 can be used to modify the gain. The output stage is the balanced transformerless(BTL) driver. The bias voltage VP is described as follows.
62K V P = ( VCC - V BE - V CE ( SAT ) ) x --------------------------- + V CE ( SAT ) 60K + 62K VCC - V BE - V CE ( SAT ) = ------------------------------------------------------------ + V CE ( SAT ) 1.97

2. Thermal Shutdown
VCC
The TSD circuit turns activated when the junction temperature becomes over 175C. It cuts off the bias current on the output driver and keeps all the output drivers off. Meanwhile, the junction temperature begins to decrease. The TSD circuit can be deactivated when the unction temperature falls under 150C, so the output driver begins operating in normal condition The TSD circuit has the hysteresis temperature of 25C.

3. Power Save Function
When the pin22 is high, the TR Q3 is turned on and Q4 is off, so the bias circuit is enabled. On the other hand, when the pin22 is Low (GND) , the TR Q3 is turned off and Q4 is on, so the bias circuit is disabled. that is, it will make all the circuit blocks except for variable regulator off, so low power quiescent state can be established. Truth table is as follows. Pin#22 High Low FAN8039BD3 Power Save Off Power Save On

4. Variable Regulator
A 33uF capacitor is used as a ripple eliminator in the external circuit. Therefore, output voltage, Vout can be calculated as follows.

In order to reduce the heating problem on regulator output TR,Q1, a resistor R3 can be used and calculated as follows.

* Rotational direction control The forward and reverse rotational direction is controlled by FWD (pin10) and REV (pin11) , so the conditions are as follows. INPUT FWD H H L L REV H L H L OUT 1 Vp H L Vb OUTPUT OUT 2 Vp L H Vb State Short Brake. Forward Reverse High Impedance
* Vp(Power Bias voltage) can be approximately 3.75V where Vcc1and Vcc are 8V. * Vb(Brake Bias voltage) can be approximately 1.7V where Vcc1and Vcc are 8V. * Motor speed control (Where VCC=VCC1=8V) - The maximum torque can be obtained when the pin 9(CTL) is open. - If the voltage on pin 9(CTL) is 0V, the motor will not be operating.
