Analog Devices ADM705
The ADM705/ADM706/ADM707/ADM708 microprocessor supervisory circuits are suitable for monitoring 5 V power supplies/batteries and microprocessor activity. The ADM705/ADM706 provide power-supply monitoring circuitry that generate a reset output during power-up, powerdown, and brownout conditions. The reset output remains operational with VCCFEATURES
