ADI ADM708ARZ

简单复位/加电复位4.4V1

Overview

The ADM708ARZ series Supervisory Circuit that can be suitable for monitoring 5V power supplies/batteries and microprocessor activity. The ADM705/ADM706 provides power-supply monitoring circuitry that generates a reset output during power-up, power-down and brownout conditions. The reset output remains operational with VCC as low as 1V. Independent watchdog monitoring circuitry is also provided. This is activated if the watchdog input has not been toggled within 1.60 seconds. In addition, there is a 1.25V threshold detector to warn of power failures, to detect low battery conditions or to monitor an additional power supply. An active low, debounced manual reset input (MR) is also included.
