BQ2947: CD pin Voltage

Part Number: BQ2947

HI Team,

How much voltage will apply at CD pin during OV condition? DS mentioned CD pin will be charged by VCD, however VCD value isn't clear on DS.

Regards,

    Hi Kotara,
    VCD is approximately 1.5V. Its value is not expected to be used by any external circuit, but its absence from the data sheet does not allow guidance for selecting an appropriate voltage capacitor. Please use the 1.5V nominal maximum to select an appropriate capacitor. I have flagged the data sheet for a future update to include VCD level. Thank you for bringing this to our attention.
