Analog Devices Inc. ADM6710DARJZ-REEL7

Description
The ADM6710 is a low voltage, high accuracy supervisory circuit that monitors up to four system supply voltages. It 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.
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: supply (or to Vcc in the case of the 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; or IN: exceeds 1 V, whereas for the ADM6710Q, the output remains valid as long as Vcc 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.
