5. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Remarks to reset relay
The duration of the over- or undervoltage pulses determines the enable- and reset outputs. A
pulse duration shorter than the debounce time has no effect on the outputs. A pulse longer than
the debounce time results in the first reset delay. If a pulse appears during this delay, a second
delay time is triggered. Therefore, the total reset delay time can be longer than specified in the
data sheet.
