ABSOLUTE MAXIMUM RATINGS
V DD to V SS ..........................................................-0.3V to +100V
DET, RTN, WAD, PG, 2EC to V SS ....................... -0.3V to +100V
CLS to V SS ..............................................................-0.3V to +6V
Maximum Current on CLS (100ms maximum) .................100mA
Continuous Power Dissipation (T A = +70 N C) (Note 1)
10-Pin TDFN (derate 24.4mW/ N C above +70 N C)
Multilayer Board ........................................................1951mW
Package Thermal Resistance (Note 2)
B JA .................................................................................4 N C/W
B JC ................................................................................9 N C/W
Operating Temperature Range .......................... -40 N C to +85 N C
Maximum Junction Temperature.....................................+150 N C

Note 1: Maximum power dissipation is obtained using JEDEC JESD51-5 and JESD51-7 specifications.
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
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
(V IN = (V DD - V SS ) = 48V, R DET = 24.9kω, R CLS = 619ω. RTN, WAD, PG, and 2EC unconnected, all voltages are referenced to V SS,
unless otherwise noted. T A = T J = -40 N C to +85 N C, unless otherwise noted. Typical values are at T A = +25 N C.) (Note 3)
