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 pin23.
The input signal through the pin3 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 drives the power TR of the output stage according to 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 pin3 is below the V
REF
, the motor rotates in forward direction.
When the input voltage through the pin3 is above the V
REF
, the motor rotates in reverse direction.
To change the gain, pin4 or 24 can be used.
5. Connect a by-pass capacitor, 0.1
μ
F between the supply voltage source.
6. Radiation fin is connecting to the internal GND of the package.
Connect the fin to the external GND.
