Device description

DocID030766 Rev 2.0

31/41

Depending on the status of the OC_SEL signal (see Table 11: "OC protection selection")

the OC event is acting directly on the control logic of the gate driver switching off all high-

side gate outputs, and consequently the external high-side power switches.

When the overcurrent condition disappears, the latched overcurrent signal is released only

after all the high-side outputs are kept low for at least tOCrelease time. (Refer to Figure 16:

"Driver logic overcurrent management signals").
