7 / 10 page LB11920 No.7229-7/10 Continued from preceding page. Pin No. Pin name Function Equivalent circuit 11 S/S Start/stop control pin. Start with L and stop with H or in the open condition. VCC 3.5k Ω 11 12 VCC Control circuit power pin. 13 GND1 GND pin (control circuit block). 14 PWM Pin to set the PWM oscillation frequency. Connect a capacitor between this pin and GND. VCC 200 Ω 14 15 TOC PWM waveform comparator pin. Normally use with “L” or open. To control the output duty by applying the voltage to this pin without using the PWMIN pin, set the PWMIN pin to “L”. VCC 15 16 CSD Pin to set the operation time of motor lock protection circuit. Insertion of a capacitor (about 10 μF) between CSD and GND enables setting of the protection operation time of about 3.5sec. VCC 300 Ω 16 Continued on next page. |
