Self-Test and Alarm Conditions
If an alarm occurs just prior to or just after the self-test pulse is
initiated, the alarm causes the self-test to fail. The time span for
Self-Test Timing and Monitoring Strategy
When monitoring the signals for self-test on the AD8280, note
the following items:
this condition depends on the deglitch time.
?
After initiating a self-test of the AD8280 with a rising edge
?
Deglitch time = 0.0 sec. The part fails self-test if an alarm
occurs in the time period from 20 ms before the leading

pin remains valid up to t RE max.
edge of the self-test pulse to 20 ms after the leading edge
of the self-test pulse.
?
When the rising edge of the TESTI pulse occurs, the user
should monitor the AVOUTxx pin to make sure that it is

occurs in the time period from 120 ms before the leading
edge of the self-test pulse to 120 ms after the leading edge
of the self-test pulse.
Therefore, in the unusual circumstance that the part fails self-
test and there is an alarm condition state after the self-test, it
is recommended that the user retest the part to ensure that
an alarm did not occur just prior to or just after initiating the
self-test.
The self-test works when the part is in the shared alarm mode
?
?
After the t ST max time has elapsed, the user can verify that
the AVOUTxx pin has changed to the low state, indicating
that the part or parts passed the self-test. The user must
also ensure that the minimum length of the TESTI pulse
is greater than t ST max. The status of the self-test on the
AVOUTxx pin is valid until t STV min after the trailing edge
of the TESTI pulse.
The alarm state is valid again t FE max after the trailing edge
of the pulse.
or in the separate alarm mode. When the part is in the separate
alarm mode, the self-test status on an output pertains only to
that portion of the internal circuit relevant to the condition being
monitored: overvoltage, undervoltage, or overtemperature.
