... ADM705 and ADM706 and only differ in that a watchdog timer function is not available. Instead, an active high reset output (RESET) is available as well as the active low reset output ( RESET ). The ADM707 and ADM708 are identical except for the reset threshold monitor levels, which are 4.65 V and 4.40 V, respectively. ...

... V being below the reset threshold low signal on the CC manual reset input (MR). RESET remains low whenever V threshold (4. ADM705/ADM707, 4. ADM706/ADM708). It remains low for 200 ms after V goes above the reset threshold or MR goes from low to CC high. A watchdog timeout does not trigger RESET unless WDO is connected to MR. ...

... CC cessor is held in a stable shutdown condition as the power supply voltage ramps up. In addition to RESET , an active high RESET output is also available on the ADM707/ADM708. This is the complement of RESET and is useful for processors requiring an active high reset signal. MANUAL RESET The manual reset input ( MR ) allows other reset sources, such as a manual reset switch, to generate a processor reset ...
