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
6 shows the push-pull operation where OE pin must
be kept high and the NIN pin controls the switch. If
the OUT signal differs from what declared in tables 4,
5 and 6 (due to external forcing) for more than 14 µs
(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.
