Description

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 IN2supply (or to VCCin the case of the ADM6710Q) of typically 10 μA. After 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 IN1or IN2exceeds 1 V, whereas for the ADM6710Q, the output remains valid as long as VCCexceeds 2 V.Unused monitored inputs must not be allowed to float or to be grounded, instead they must 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 +125°C.APPLICATIONSTelecommunicationsMicroprocessor systemsDesktop and notebook computersData storage equipmentServers/workstations
