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.
Applications
Speed control of various motors including capstan motors, drum head motors, and reel motors
Features
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.
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.
Absolute maximum ratings (Ta = 25 C)
