Datasheet
6 Characteristics
6.1 Absolute Maximum Ratings
Stresses beyond those listed in Table 1 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 in Section 5
Electrical Characteristics is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

As the AS3691 is not directly connected to this supply. Only the parameters V INVREG , V IN5V and
V IN15V have to be guaranteed by the application
All pins except CURR1, CURR2, CURR3 and CURR4
Depending on actual PCB layout and especially number of vias below the exposed pad – see layout
recommendations; can be improved e.g. with Al-PCB or airflow
