BQ25703A: bq25703A / Resistor value in VBUS, SRN and VSYS

Part Number: BQ25703A

Hi,

The customer is asking the resistor value in VBUS, SRN and VSYS. They are asking it because they'd like to estimate rough leakage current into these pins. I know that it should be adjusted by register setting so let me know rough value like around 10k ohm or 100k ohm totally.

Best Regards,

    Those resistor leakage current could be just part of the pin leakage current. VBUS quiescent current is listed on the datasheet spec table.

    SRN and SRP mismatch leakage current is listed on the spec table.

    Please don't put a series resistor on VSYS pin because it could be internal LDO's input source.
