There is a good new that DIN LP8866-Q1
For all integrated circuits (IC's, e.g. HSD, LSD, Others), the device will not lose control of the Gate/input signal when exposed to a negative gate to source bias. This can generally occur if the device has an open circuit (gate/input is near zero volts (commanded OFF) and the source is pulled high via a current source on the output used for open circuit detection, or if the source/output is shorted to battery). Can ion-migration occur resulting in a Vt shift, which may allow the device to be partially ON when the gate/input is OFF?
