13 / 17 page LB11850VA www.onsemi.com 13 <LIM Pin> The minimum speed is determined by the voltage of the LIM pin. Figure 13. (RPM) CTL Duty(%) Maximum speed 0% 5 V 100% 2 V Minimum speed setup CVO pin voltage (V) 2000 4000 6000 8000 10000 1) Obtain the ratio of the minimum speed required to the maximum speed. Ra = Minimum speed/maximum speed .... <1> In the example shown in the figure above, Ra = minimum speed/maximum speed = 3000/10000 = 0.3. 2) Obtain the product of the duty ratio at which the maximum speed is obtained and the value in equation <1>. Ca = Duty ratio at maximum speed × Ra .... <2> In this example, Ca = duty ratio at maximum speed × Ra = 0.8 × 0.3 = 0.24. 3) Obtain the required LIM pin voltage. LIM = 5 − (3 × Ca) .... <3> In this example, LIM = 5 − (3 × Ca) = 5 − (3 × 0.24) ≈ 4.3 V. 4) Divide the resistance of 5VREG, and generate the LIM voltage. In this example, the voltage is 4.3 V so the resistance ratio is 1 : 6. The resistance is 10 k W between 5VREG and LIM and 62 kW between LIM and GND. Figure 14. 5VREG VREF CVI SOFT LIM |
