TCAN1057A-Q1: Input capacitance

Part Number: TCAN1057A-Q1


Hi team,

are there any concerns about having a 1uF decoupling capacitor instead of the recommended 100nF at the Vcc pin?

Best regards

Felix

    Hi Felix,

    No major concerns for the device if close to the VCC pin. And system engineers would have to decide based on their respective systems.

    I.e., what is typically common with larger caps is insufficiency in filtering high frequency, slowing down VCC rise or increase inrush current in systems sensitive to POR or UVLO timing. Hence, no concerns if there are no system sensitivities, thanks.

    Best Regards,

    Michael.
