The ADM6710 series low-voltage high-accuracy Supervisory Circuit for use with microprocessor system. The ADM6710Q offers three adjustable thresholds for monitoring voltages down to 0.62V. 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 IN2 supply (or to VCC in the case of the ADM6710Q) of typically 10μA. After all voltages rise above the selected threshold level, the reset signal remains low for the reset timeout period (200ms typical). The ADM6710 output remains valid as long as IN1 or IN2 exceeds 1V, whereas for the ADM6710Q, the output remains valid as long as VCC exceeds 2V.
Accurate monitoring of up to four power supply voltages
