EMW3166
2. Electrical Parameters
Operating Ratings 2.1
EMW3166 enters an unstable condition whenever the input voltage dips below the minimum value of supply
voltage. This condition must be considered during design of the power supply routing, especially if operating from a
battery.

Absolute maximum ratings (voltage) 2.2
Stresses above the absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these conditions is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
