VP
The voltage, VREF is the reference voltage given by the external bias voltage of the pin #23. The input signal (VIN) through
pin #12,20 is amplified by 10k/10k times and then fed to the level shift. The level shift produces the current due to the differ-
ence between the input signal and the arbitary reference signal. The current produced as + ∆I and -∆I is fed into the driver
Amp. The driver Amp. operates the power TR. of the output stage as the 2 times gain(1+10k/10k) according to the state of the
input signal.
∆V
VIN = VREF + ∆V∆I = ----------

DO + = VP + ∆I • 10K • 1 + ---------- = VP + 2∆V

GAIN = 20log
= 12dB
∆V
If it is desired to change the gain, then the pin #3 or 25 can be used.
The output stage is the balanced transformerless (BTL) driver.
The bias voltage VP is expressed as
62K
VP = (VCC – VBE – VCE(SAT)) × --------------------------- + VCE(SAT)
60K + 62K
VCC – VBE – VCE(SAT)
= ------------------------------------------------------------ + VCE(SAT)

2. Thermal Shutdown
VCC
When the chip temperature reaches to 175°C, then the TSD circuit is
activated.
I
REF
Output driver
bias
This shuts down the bias current of the output drivers, and all the output
drivers are in cut-off state. Thus the chip temperature begins to decrease.
R1
Q0
R2
when the chip temperature falls to 150°C, the TSD circuit is deactivated
and the output drivers are normally operated.
Hysteresis
Ihys
R3
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.
VCC
Main Bias
(except for
variable reg.)
That is, this function will cause all the circuit blocks of the chip except
for the variable regulator to be in the off state. thus the low power quies-
cent state is established

4. Variable Regulator
The VREF is the output voltage of the referenced biasing circuit
and is the reference voltage of the regulator. (VREF=2.5V) The
external circuit is composed of a capacitor, 33uF, which is used
as a ripple eliminator The output voltage, VOUT is decided as
follows.

• Where Vp(Power reference voltage) is approximately about 3.75V at VCC1,VCC = 8V
• Motor speed control (When VCC=VCC1=8V)
- The almost maximum torque is obtained when the pin 9,(CTL) is open.
- If the voltage of the pin 9,(CTL) is 0V, the motor will not operate.
