(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under Section 4.3 is not implied.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

If VBAT exceeds above rating a device to drop down the voltage before applied to the device.

(3)

If VBUS exceeds above rating an external voltage protection on the line is mandatory between the VBUS line and the TUSB1211.

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
