The ADM705/ADM706/ADM707/ADM708 microprocessorsupervisory circuits are suitable for monitoring 5 V powersupplies/batteries and microprocessor activity.
The ADM705/ADM706 provide power-supply monitoringcircuitry that generate a reset output during power-up, powerdown,and brownout conditions. The reset output remainsoperational with VCC as low as 1 V. Independent watchdogmonitoring circuitry is also provided. This is activated if thewatchdog input has not been toggled within 1.60 sec.
In addition, there is a 1.25 V threshold detector to warn ofpower failures, to detect low battery conditions, or to monitor anadditional power supply. An active low, debounced manual resetinput (MR) is also included.
The ADM705 and ADM706 are identical except for the resetthreshold monitor levels, which are 4.65 V and 4.40 V, respectively.
The ADM707 and ADM708 provide a similar functionality tothe ADM705 and ADM706 and only differ in that a watchdogtimer function is not available. Instead, an active high resetoutput (RESET) is available as well as the active low reset output(RESET). The ADM707 and ADM708 are identical except forthe reset threshold monitor levels, which are 4.65 V and 4.40 V,respectively.
All devices are available in narrow 8-lead PDIP and 8-lead SOICpackages.
