APPLICATION INFORMATION
1. MUTEM
When the mute pin #7 is open or the voltage of the mute pin #7 is below 0.5V, the mute circuit is activated so
that the output circuit will be muted.
When the voltage of the mute pin is above 2V, the mute circuit is stopped and the output circuit is operated
normally.
If the chip temperature rises above 175
C, then the TSD (Thermal shutdown) circuit is activated and the output
circuit is muted.
2. TSD (THERMAL SHUTDOWN)
The V
REF BG
is the output voltage of the band-gap-referenced bias in circuit and acts as the input voltage of the
TSD circuit.
The base-emitter voltage of the TR, Q11 is designed to turn-on at below voltage.
V
BE
= V
REF
BG
R12 / (R11 + R12) = 460mV
When the chip temperature rises up to 175
C, then the turn-on voltage of the Q11 would drop down to 460mV.
(Hysteresis: 25
C) Hence, the Q11 would turn on so the output circuit will be muted.

3. OP-AMP
Op-amp is integrated in the IC for user's convenience.
4. DRIVER
The voltage, V
REF
, is the reference voltage given by the bias voltage of the pin #23.
The input signal through the pin #3 is amplified by 10k/10k times and then fed to the level shift.
The level shift produces the current due to the difference between the input signal and the arbitrary reference
signal. The current produced as +
I and
-
I is fed into the driver buffer.
Driver buffer operates the power TR of the output stage according to the state of the input signal.
The output stage is the BTL driver and the motor is rotating in forward direction by operating TR Q1 and TR
Q4. On the other hand, if TR Q2 and TR Q3 is operating, the motor is rotating in reverse direction.
When the input voltage through the pin #3 is below the V
REF
, then the direction of the motor in forward
direction.
When the input voltage through the pin #3 is above the V
REF
, then the direction of the motor in reverse
direction.
If it is desired to change the gain, then the pin #4 can be used.
The gain (A
V
) of the drive circuit is as follows.
