D.C. (*) for 4.5V ≤ VS < 6.5V, IO ≤ 2A diag. table is valid. (**) If one diag.status shows the overtemp. 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 behaviour will be related to the overdrop sensing which will be used as over load recognition. 5V t t UI IO SC 5V t 5A td OL UD IO IO UC Figure 1: Diagnostic overload delay time L9386MD 4/10 |
