Note 1: SHDN may be forced to 12V for the purpose of debugging prototype boards using the no-fault test mode, which disables
fault protection and overlapping operation.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
