In applications as a high side driver the OMNIFET’s source is connected to the ASIC ground,
which switches together with the load circuit. Changes in the ASIC’s ground potential of up to
58V, and rise and fall speeds of up to 58V/μs are permitted.

Description
From the functional view the chip can be divided into the following units:
A driving circuit, which implements a current-controlled switching of the OMNIFET with current
pulses of approximately +30 mA, and makes the following further functions available:
Detection of the operating condition of the OMNIFET and generation of an error status
signal (Output of a current of approximately 0.5 mA in the event of an error)
Defined delay of the switching-on-impulse of approximately 2.0μs and implementation of a
delay of the switch-off-impulse of smaller than 0.5μs
Defined (current-controlled) rise/fall times of approximately. 2.0μs/1,0μs
Disconnection of the switching-on-impulse after approximately 5,0μs and connecting a cur-
rent source of approximately 3 mA whilst the OMNIFET is switched on for the supply of the
OMNIFET’s protective circuits and error recognition
Current sinking at the OMNIFET drive pin of up to 30 mA during the off state ensures a
safe off status.
