GENERAL DESCRIPTION

The ADM6710 output remains valid as long as IN₁or IN₂

exceeds 1V, while for the ADM6710Q the output remains valid

as long as V_CCexceeds 2 V.

The ADM6710 is a low voltage, high accuracy supervisory

circuit. This device monitors up to four system supply voltages.

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 IN₂supply (or to V_CCin the case of the

ADM67109Q) 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 incorporates a variety of internally pretrimmed

undervoltage threshold options for monitoring 5.0 V, 3.3 V, 3.0

V, 2.5 V and 1.8 V supply voltages. The device offers up to three

adjustable thresholds for monitoring voltages down to 0.62 V.

The ADM6710 is available in a 6-lead SOT-23 package and is

suitable for use in a variety of voltage monitoring applications.
