JAJSU29 March 2024 ISOUSB211-Q1
ADVANCE INFORMATION
Until all power supplies on both sides of ISOUSB211-Q1 are above their respective UVLO thresholds, the device ignores any activity on the bus lines on both upstream and downstream side. Once the power supplies are above their UVLO thresholds, the device is ready to respond to activity on the bus lines. When the power supplies on side 1 are up, this is indicated on side 2 by V1OK = High. Similarly, V2OK = High indicates that Side 2 is fully powered up.
