Absolute Maximum Ratings
These are stress ratings only and functional
operation of the device at these ratings or any other
above those indicated in the operation sections of the
specifications below is not implied. Stresses beyond
those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to
any Absolute Maximum Rating condition for extended
periods may affect device reliability and lifetime.

Electrical Characteristics
Specifications are for Operating Junction Temperature of TJ = 25°C only; limits applying over the full Operating
Junction Temperature range are denoted by a “•”. Typical values represent the most likely parametric norm at TJ =
25°C, and are provided for reference purposes only. Unless otherwise indicated, VIN=12V
