Description

The ADM706P/R/S/T and the ADM708R/S/T microprocessor supervisory circuits are suitable for monitoring either 3 V or 3.3 V power supplies.

The ADM706P/R/S/T and the ADM708R/S/T  provide the following functions: 1. Power-supply monitoring circuitry which generates a Reset output during power-up, power-down and brownout condi- tions. The reset output remains operational with VCC as lowas 1 V. 2. Independent watchdog monitoring circuitry which is acti- vated if the watchdog input has not been toggled within 1.6 seconds. 3. A 1.25 V threshold detector for power fail warning, low bat-tery detection, or to monitor an additional power supply. 4. An active low debounced manual reset input (MR).

The ADM706P/R/S/T and the ADM708R/S/T  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 2.63 V. It differs only in that it has an active high reset output.

The ADM706P/R/S/T and the ADM708R/S/T provide the same functionality as the ADM706R/S/T and only differ in that: 1. A watchdog timer function is not available. 2. An active high reset output (RESET) in addition to the active low (RESET ) output is available. All parts are available in 8-lead DIP and narrow SOIC packages.
