ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

((VIN = 2.75V to 13.2V and VAUXIN = 0V) or (VIN = 1V and VAUXIN = 2.75V to 13.2V), RSTH = open, RFTH = 0, VUVLO = 1V, VOVI = 0V,

TA = -40°C to +85°C, unless otherwise noted. Typical values are at VIN = 12V and TA = +25°C. See the Typical Operating Circuit.) (Note 1)

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.
