Definition of the logic signals

Symbol Logic meaning

Level meaning

IN Control input for the driver, the input

is current controlled, i.e.:

a) According to to a current from IIN= -0,1 mA Ü

0,1mA to DGND externally pro-

duced

b) According to no current (< 5 mA) IIN = 0

Ü

STAT

Accumulated error status signal for

the controlled OMNIFET,

the output is

current controlled, i.e.:

a) fault condition according to a

current from 0,35 mA to 0.5 mA

from the ASIC to DGND

b) normally operation according to

no current

ISTAT = -0,5mA Ü

ISTAT = 0

Ü

a) appropriate driver output goes

high (according to VOUT = VTR)

b) appropriate driver output goes

low (according to VOUT = VSOURCE)

Error at the OMNIFET during the on-

status (signal is valid after termina-

tion of the switch-on procedure)

a) an error of the OMNIFET during

the on-status,

b) normal operation or off-status of

the OMNIFET
