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 + ∆V∆I = ---------10K 10K DO + = V P + ∆I • 10K • 1 + ----------- = V P + 2∆V 10K 10K DO – = V P – ∆I • 10K • 1 + ----------- = V P – 2∆V 10K V OUT = ( DO+ ) – ( DO- ) = 4∆V 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 ) ) × ---------------------------- + V CE ( SAT ) 60K + 62K VCC – V BE – V CE ( SAT ) - + V CE ( SAT ) = -----------------------------------------------------------1.97 8 5-CH MOTOR DRIVER 2. Thermal Shutdown VCC The TSD circuit turns activated when the junction temperature becomes over 175°C. 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 150°C, so the output driver begins operating in normal condition The TSD circuit has the hysteresis temperature of 25°C. IREF Output driver bias R1 Q0 R2 Hysteresis Ihys R3 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 FAN8039BD3 High Power Save Off Low Power Save On VCC Main Bias (except for variable reg.) Q4 22 Q3 4.
