Application Information
1. Mute Function
When the mute (pin 7) is high level, the bias circuit of BTL driver is activated. On the other hand, when the mute (pin7) is
open or low level, the bias circuit of BTL driver is disabled. So that the 4-channels BTL driver output circuit will be muted.
2. TSD (Thermal Shutdown) Function
The V
REFBG
is the output voltage of the band-gap-referenced biasing circuit and acts as the input voltage of the TSD
circuit.
The base-emitter voltage of the transistor, Q11 is designed to turn-on at below voltage.
If the chip temperature rises above 175
C, then the TSD circuit is activated and the output circuit is muted. The TSD circuit
has the hysteresis temperature of 25
C.

The V
REFBG
is the output voltage of the band-gap-referenced biasing circuit and is the reference voltage of the regulator.
The external circuit is composed of the transistor(PNP), KSB772 and a capacitor(C1), 100
F, and the capacitor is used as a
ripple eliminator and should have a good temperature characteristics.
The output voltage, V
OUT
is decided as follows.
4. Loading Motor Driver
4.1 Truth table and Operation
The input voltages of (5V and 0V) or (0V and 5V) pairs are applied to the input pin #9 and #14 respectively.
When the input voltages are applied to the input pin #9 and #14, then the output of the comparator is decided depends on the
input voltage status.
As shown in the above diagram, the difference voltage,
V, is applied to the both terminals of the motor. The direction of
the motor is decided by the voltage difference, +
V and -V.
The output characteristics is as follows,
- If pin # 9=5V and #14=0V, then pin # 15=+
V and #16= -V, hence the motor turn in forward direction.
- If pin # 9=0V and #14=5V, then pin # 15=
-V and #16=+V, hence the motor turn in reverse direction.
- If pin # 9=5V and #14=5V, then
V=0V, hence the motor stop.
- If pin # 9=0V and #14=0V, then
V=0V, hence the motor stop.
4.2 Loading Motor Speed Control
If the torque of the loading motor is too low when it is used with the pin #20 open, then it should used as the above diagram.
The desired torque could be obtained by selecting the appropriate resistor R as shown in the left diagram.
If it is necessary, the zener diode can be used as in the right diagram.
The maximum torque is obtained when the applied voltage at pin #20 is about 6.8V (at V
CC
=8V).

6. BTL Driver (CH1, CH2, CH3 and CH4)
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 Transistor 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 transostor Q1 and Q4. On the
other hand, if transistor Q2 and 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.
When the bias voltage of the pin #23 is below 1.4V, then the output circuit is muted.
Hence for the normal operation, the bias voltage should be used in 1.6V~6.5V.
7. Connect a by-pass capacitor, 0.1
F between the supply voltage source.
1. Radiation FIN is connecting to the internal GND of the package.
2. Connect the FIN to the external GND.
