Following equation simplifies under the assumption of
The energy, which is converted into heat, is limited by the thermal design of the component. See
maximum allowed energy dissipation as function of the load current.
5.1.4
In case of inverse current, meaning a voltage V
I
the IN pin is HIGH, the power DMOS is already activated and keeps ON. In case, the input goes from “L” to “H”,
the DMOS will be activated. Under inverse condition, the device is not overtemperature / overload protected. The
IS pin is high impedance. Due to the limited speed of INV comparator, the output voltage slope needs to be limited.
