PACKAGE THERMAL CHARACTERISTICS (Note 2)
TQFN
Junction-to-Ambient Thermal Resistance (q_JA)...........36°C/W
Junction-to-Case Resistance (q_JA)....................................3°C/W
Note 1: When F1 and F2 are connected to a voltage higher than V_CC, some current will be sinked (see the Detailed Description).
Note 2: 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.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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
(V_CC = 5.0V Q 5%, T_A = -40NC to +85NC, unless otherwise noted. Typical values are at V_CC = 5.0V and T_A = +25NC.) (Note 3)
