General Description
ADM708 General Description
The ADM705ADM708 are low cost P supervisory circuits. They are suitable for monitoring the 5 V power supply/battery and can also monitor microprocessor activity.The ADM705/ADM706 provide the following functions: 1.Power-On Reset output during power-up, power-down and brownout conditions. The RESET</a> output remains opera-tional with VCC as low as 1V.2.Independent watchdog timeout, WDO</a>, that goes low if thewatchdog input has not been toggled within 1.6 seconds.3.A 1.25 V threshold detector for power-fail warning, low battery detection or to monitor a power supply other than 5V.4.An active low debounced manual reset input (MR</a>).The ADM707/ADM708 differ in that:1.A watchdog timer function is not available.2.An active high reset output in addition to the active low output is available.
Two supply-voltage monitor levels are available. The ADM705/ADM707 generate a reset when the supply voltage falls below 4.65 V, while the ADM706/ADM708 require that the supply fall below 4.40 V before a reset is issued.
All parts are available in 8-lead DIP and SOIC packages. The ADM707 and ADM708 are also available in space-saving microSOIC packages.
