... An active low debounced manual reset input (MR). The ADM706R, ADM706S, ADM706T are identical except for the reset threshold monitor levels which are 2.63 V, 2.93 V, and 3.08 V respectively. The ADM706P is identical to the ADM706R in that the reset threshold is 2. differs only in that it has an active high reset output. ...

... V. This ensures that the microprocessor is held in a stable shutdown condition as the power supply starts up. The ADM706P provides an active high reset (RESET) signal; the ADM706R/S/T provides an active low (RESET) signal; while the ADM708R/S/T provides both RESET and RESET. REV.
