*1. The recommended range of the resistance (Rosc) for oscillation frequency is Rosc
= 120 k to 510 k (fOSC = 286 kHz to 1.133 MHz).
This range of oscillation frequency is the typical value when an ideal resistor is connected externally. In actual use, it is necessary to
take account the dispersion of an IC (
±10%) into this value.
*2. Set max. duty; Between 47 and 88.5 % (RDuty/ROSC = 0.5 to 3.2); the oscillation frequency is 500 kHz or more
Between 47 and 80 % (RDuty/ROSC = 1.0 to 3.2); the oscillation frequency is less than 500 kHz
This range of max. duty is the typical value when an ideal resistor is connected externally. In actual use, it is necessary to take
account the dispersion of an IC (
±5%) into this value.
*3. The short-circuit protection time can be set by the external capacitor. Although the maximum set value by the external capacitor is
unlimited under the ideal condition, set CSP
= approx. 0.47 F as a target maximum value due to discharge time of the capacitor.
