OPERATING MODES
The iC-DXC can be operated in high-side (PNP), low-
side (NPN) and push-pull (PP) switch mode. Figure 4
shows the high-side operation where NIN pin must be
kept low and the OE pin controls the switch. Figure 5
shows the low-side operation where NIN pin must be
kept high and the OE pin controls the switch. Figure
be kept high and the NIN pin controls the switch. If
the OUT signal differs from what declared in tables 4,
(cf. Electrical Characteristics No. 510), this event will
be signalled by a low level at MON output. In case of
a short circuit at OUT and resulting temperature shut-
down, logic level of MON will be undefined.
