3. OP-AMP
OP-amp is integrated in the IC for user’s convenience.
4. DRIVER
• The voltage, V
• 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
• 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
• When the input voltage through the pin3 is below the V
• When the input voltage through the pin3 is above the V
• To change the gain, pin4 or 24 can be used.
5. Connect a by-pass capacitor, 0.1 F between the supply voltage source.
6. Radiation fin is connecting to the internal GND of the package.
