Motor driver ICs
FG system speed servo controller
BA6302A / BA6302AF / BA6303 / BA6303F
The BA6302A /A F and BA6303 / F are FG-system servo control ICs suitable for controlling the speed of VCR motors. They contain a hysteresis FG amplifier section, an S / H system F / V conversion section, an error amplifier section, and an inverter section. Motor speed can be set with a high degree of freedom by an external CR. The start-up circuit allows quick and precise motor starting. Motor speed can be controlled precisely at different levels by installing an FG program counter between the FG amplifier output and the F / V conversion input.
