Application Information
1. Driver (Except For Loading Motor Driver)
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).
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.

2. Thermal Shutdown
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
.
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.
4. Variable Regulator
A 33uF capacitor is used as a ripple eliminator in the external cir-
cuit. 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

5. Loading Motor Driver
Rotational direction control
The forward and reverse rotational direction is controlled by FWD (pin10) and REV (pin11) , so the conditions are as
follows.
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.
