DRV8818: how the select the capacitor for VCP and CP1, CP2

Part Number: DRV8818

Dears

DRV8818 for 24V supply, customer have a confuse about he capacitor on VCP and CP1, CP2.

one is the capacitance, the 0.22uf is a typical value, is there a min to max?

the other one is the voltage rating, for 24V supply, will 16V capacitor works?

thanks

  • Hi Jun,

    one is the capacitance, the 0.22uf is a typical value, is there a min to max?

    >>> +/- 20% is acceptable (180nF to 270nF)

    the other one is the voltage rating, for 24V supply, will 16V capacitor works?

    >>> 16V works because the voltage across the VCP capacitor is ~12V.
