Note:

1)

The maximum driver voltage VTR at full function it is VTR = 42V. At VTR = 60V in the load dump case all

defined functions are staying valid (function state A). In this state it is possible that some times some parame-

ters are different from the specified value, but in every time the switch off delay is shorter then the switch on

delay.

3)

4)

This is the input current of the OMNIFET in the on-state

5)

This is a chip internal dynamical limitation of the output voltage.

6)

< 1 pF). The tolerance of this current controls the switch timing.
