NOTE

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.

2) Valid for an input current IIN = 0A. This possibility of the output OUT is valid the off state.

3) Valid for an input current IIN = 100µA. This possibility of the output OUT is valid the on state.

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) Correspondent with the output current of the control circuit. The capacity on the pin IN has to be low (CPIN extern

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