7 / 9 page LB11660RV www.onsemi.com 7 *5 <Hall input> Wiring need to be short to prevent carrying of the noise. The Hall input circuit is a comparator having a hysteresis of 20mV. It is recommended that the Hall input level be more than three times (60mVp-p) this hysteresis. *6 < PWM oscillation frequency setting capacitor > The oscillation frequency is 23kHz when CP = 200pF and 46kHz when CP = 100pF, and this serves as the PWM fundamental frequency. For the most part, the PWM frequency can be obtained from the following formula: f [kHz] (4.6106) ÷C [pF] *7 <RD output> This is the open collector type output, which outputs ''L'' during rotation. It is set to 'OFF' when a lock is detected. This output is left open when not in use. *8 <HB pin> This is a Hall element bias pin, that is, the 1.25V constant-voltage output pin. *9 <RMI pin> Lowest speed setting pin for speed control. The minimum output duty setting is made with R3 and R4. The R4 is left open to stop operation at a duty ratio of 0%.
