ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(+3V ≤ V

≤ +5.5V, T

A =

-55°C to +125°C, unless otherwise noted.)

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.

OT, SCL, SDA to GND.............................................-0.3V to +6V

ADD to GND .................................................-0.3V to (V

+ 0.3V)

Current into Any Pin............................................................±5mA

OT Sink Current.................................................................. 20mA

Continuous Power Dissipation

6-Pin SOT23 (derate 9.1mW/°C above +70°C)............727mW

Junction Temperature......................................................+150°C

Storage Temperature Range .............................-60°C to +150°C

Lead Temperature .............................................................Note 1

ESD Rating (Human Body Model)......................................2000V

Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device

can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recom-

mended in the industry-standard specification, IPC/JEDEC J-STD-020A, paragraph 7.6, Table 3 for IR/VPR and Convection

Reflow. Preheating is required. Hand or wave soldering is not allowed.
