Operating voltage of sense filter capacitor of LTC3877

Hello,

The maximum voltage across the 220nF filter capacitors will be well below 0.2V. The actual voltage will be limited by the current sense thresholds. For ILIM=INTVCC:

• The maximum voltage across the 220nF capacitor from SNSD+ to SNS- will be 34mV.
• The maximum voltage across the 220nF capacitor from SNSA+ to SNS- will be 158mV.

The current sense thresholds from the EC table are inserted below for reference.

Best regards,

Mike
