ADM708 Datasheet (Analog Devices) - Low Cost Microprocessor Supervisory Circuits

ADM708, Low Cost Microprocessor Supervisory Circuits

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.
