Overview
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.
FApplications Speed control of various motors including capstan motors, drum head motors, and reel motors FFeatures 1) S / H system F / V converter allows speed setting with a stable external CR.
2) High hysteresis FG amplifier with high noise resistance.
3) Start-up circuit allows quick and precise motor starting.
FAbsolute maximum ratings (Ta = 25_C) 4) Motor speed can be controlled at different levels by installing an FG program counter.
5) Low current dissipation.
(VCC=9V, IQ=2.
3mA Typ.
) 6) Stable operation with either 5, 9, or 12V supply voltage.
7) Two versatile inverters are built in.
