4 / 20 page LB8503V No.A0366-4/20 Pin Assignment Pin Functions Pin No. Pin Description RC 1 One-shot multivibrator pulse width setting. Connect a resistor between this pin and VREG, and a capacitor between this pin and ground. SOFT 2 Soft start time setting. Connect a capacitor between this pin and VREG. VREG 3 6V regulator output. Connect a capacitor between this pin and ground for stabilization. VCC 4 Power supply. Connect a capacitor between this pin and ground for stabilization. CVI 5 Control voltage input CVO 6 Duty pulse signal smoothed voltage output CTL 7 Duty pulse signal input. The speed is controlled by the duty of this pulse signal. C 8 Duty pulse signal smoothing. Connect a capacitor between this pin and VREG. LIM 9 Minimum speed setting. Normally, the 6V regulator level is resistor divided to set this pin's input level. FGIN 10 FG pulse input FGOUT 11 FG pulse output GND 12 Grand pin NC 13 NC pin EI 14 One-shot multivibrator output and integrating amplifier input. A capacitor must be connected between this pin and EO for this integration. EO1 15 Integrating amplifier output. (For use with an accelerating driver IC if the command voltage becomes low (single-phase systems).) EO3 16 Integrating amplifier inverting output. (For use with an accelerating driver IC if the command voltage becomes high (three-phase systems).)
