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. 750 Motor driver ICs FBlock diagram BA6302A / BA6302AF / BA6303 / BA6303F 751 Motor driver ICs BA6302A / BA6302AF / BA6303 / BA6303F FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC=9V) 752 Motor driver ICs FExternal dimensions (Units: mm) BA6302A / BA6302AF / BA6303 / BA6303F 753
