D.C.
D.C.
1. for 4.5 V ≤ VS < 6.5 V, IO ≤ 2 A diag. table is valid.
2. If one diag. status shows the overtemperature recognition, in parallel this output will be switched OFF internally. The
corresponding channel should be switched OFF additional by its Input or ENABLE signal, otherwise the overload latch will
be set after tDOL is passed. This behavior will be related to the overdrop sensing which will be used as over load
recognition.
