TCA9416: The power up order of VCCA and VCCB

David Huang

Part Number: TCA9416

Hi team

Does the part have a specific power up order for VCCA and VCCB? (Which one should be powered up first)

Also there's a specification in the datasheet for IREF Reference-transistor current 5uA, is this the current consumption for the device?

Also is the IPASS Pass switch current 6 mA IO current limit?

Regards

    Hi David,

    There is not a supply restriction for this device. It will operate once there is power on both VCCA and VCCB. The recommended operating condition is to keep these supplies between 1.08 V and 3.6 V.

    Best,

    Danny
