External Capacitor for Charge Pump
= 13 V and 1.5 A, the logical values for Ccp 1 and Ccp 2 are as shown in the graph below:
10:1 or more. (If our recommended values (Ccp1 = 0.22 μ F, Ccp 2 = 0.022 μ F) are used, the drive conditions
in the specification sheet are satisfied. (There is no capacitor temperature characteristic as a condition.)
set the constants with a margin (the larger Ccp 1 and Ccp 2, the more the margin).
capacitance is obtained under the usage environment temperature.
When driving the stepping motor with V
Choose Ccp 1 and Ccp 2 to be combined from the above applicable range. We recommend Ccp 1:Ccp 2 at
When setting the constants, make sure that the charge pump voltage is not below the specified value and
Some capacitors exhibit a large change in capacitance according to the temperature. Make sure the above
