3. REGULATOR
The V
REF BG
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, KSB772 and a capacitor, 100
μ
F, and the capacitor is used as a ripple filter
and should have a good temperature characteristics.
The output voltage, V
OUT
is determined as follows.

4. LOADING MOTOR DRIVER
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
V, [V
REF1
+ (I
×
R)] - [V
REF1
-(I
×
R)], 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.
When the rotation speed control of the loading motor is desired, refer to the follows.
