Note :
1. When the voltage at pin 39 goes below 0.5V, the power save circuit makes the main bias current sources stop operating. As
a result, the whole circuits are disable. ( The whole circuits mean the driver circuit, the input OP amp circuit, and the normal
OP amp circuit.)

Application Information
1. Thermal Shutdown
SVCC
• The TSD circuit is activated at the junction temperature of 160°C and
deactivated at 135°C with the hysteresis of 25°C. During the thermal
shutdown, the TSD circuit keeps all the output driver off.

Q0
R2
Hysteresis
Ihys

2. CH Mute Function
• When the mute pin is high, the TR Q1 is on and Q2 is off, so the bias
circuit is enabled. When the mute pin is low (GND), the TR Q1 is off
and Q2 is on, so the bias circuit is disabled.
• During the mute on state, all the circuit blocks except for the variable
regulator remain off, and the low power quiescent state is established.
• Truth table is as follows;

3. Power Save Function
• When the pin21 is high, the TR Q3 becomes on and Q4 off, so the bias
circuit is enabled. When the pin21 is low (GND) , the TR Q3 becomes
off and Q4 is on, so the bias circuit is disabled.
• During the power save on state, this function keeps all the circuit
blocks off, and the low power quiescent state is established.
• Truth table is as follows;

4. TDS Monitor Function
• Pin 22 is TSD monitor pin, which detects the state of the TSD block
and generates the TSD-monitor signal.
• In the normal state Q5 is on, and Q6 is off. When the TSD block is
activated Q5 becomes off, and thus the voltage of pin22 keeps low.
• Truth table is as follows;

• The Vref at pin 43 is for eliminating the dc components from the input signals and can set by an exteranl circuit.
• The voltage gain from Vin to output is as follows ;
Vin = Vref + ∆V
DOP = V D + 4 ∆V
DON = V D – 4 ∆V
Vout = DOP – DON = 8 ∆V
Vout
Gain = 20 log ------------- = 20 log 8 = 18dB
∆V
•
•
•
•
Where ∆V means just ac component.
The total input to output voltage gain is the sum of the input OP amp network gain and 18dB.
The output stage is the balanced transformerless (BTL) driver.
The bias voltage Vp is expressed as ;
62k
V P = ( PVCC1 – V DP – V CESAT Q P ) × -------------------------- + V CESAT Q P

Hign impedance
• Where Vp(Power reference voltage) is approximately 3.75V at PVCC2=8V according to equation (1).
• Motor speed control (When SVCC=5V, PVCC2=8V)
- The maximum torque is obtained when the pin15(CTL) is open.
- If the voltage of the pin15 (CTL) is 0V, the motor will not operate.
- When the control voltage (pin15) is between 0 and 3.0V, the differential output voltage V(out1,out2) is about two times
of control voltage. The output gain is 6dB.
- When the control voltage is greater than 3.0V, the output voltage is saturated at the 6.0V because of the output swing
limitation.
