RESET
The ADM6710 is a low voltage, high accuracy supervisory
circuit. The device monitors up to four system supply voltages.
The ADM6710 incorporates a variety of internally pretrimmed
undervoltage threshold options for monitoring 1.8 V, 2.5 V,
3.0 V, 3.3 V and 5.0 V supply voltages. The ADM6710Q offers
three adjustable thresholds for monitoring voltages down to
0.62 V. See the Ordering Guide section for a list and description
of all available options.
If a monitored power supply voltage falls below the minimum
voltage threshold, a single active low output asserts, triggering a
system reset. The output is open drain with a weak internal
pull-up to the monitored IN 2 supply (or to V CC in the case of the
Rev. A

ADM6710Q) of typically 10 μA. Once all voltages rise above the
selected threshold level, the reset signal remains low for the
reset timeout period (200 ms typical).
The ADM6710 output remains valid as long as IN 1 or IN 2
exceeds 1 V, whereas for the ADM6710Q, the output remains
valid as long as V CC exceeds 2 V.
Unused monitored inputs should not be allowed to float or to
be grounded, instead they should be connected to a supply
voltage greater than their specified threshold voltages.
The ADM6710 is available in a 6-lead SOT-23 package. The
device operates over the extended temperature range of ?40°C
to +85°C.
