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.

ELECTRICAL CHARACTERISTICS

(VCC = +1.7V to +3.6V, VL = +1.1V to +3.6V, VCC > VL, EN = VL, CVCC = 1FF, CVL = 1FF, TA = -40NC to +85NC, unless otherwise

noted. Typical values are at VCC = +2.8V, VL = +1.8V and TA = +25NC.) (Notes 2, 3)

ABSOLUTE MAXIMUM RATINGS

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-

layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
