Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

2. The timer can be reset if there are 4 DRV cycles without overload or short circuit conditions.

3. The value is not subjected to production test, verified by design and characterization. The thermal shutdown temperature refers to the

junction temperature of the controller in order to keep the junction temperature of the power MOSFET below its maximum rating junction

temperature. Thermal Shut Down level will be adjusted after the Silicon evaluation.

4. Guaranteed by Design.
