The ADM812 series reliable voltage Supervisory Circuit suitable for use in most voltage monitoring applications. The ADM811/ADM812 is designed to monitor six different voltages, each allowing a 5 or 10% degradation of standard PSU voltages before a reset occurs. Included in this circuit is a debounced manual reset input. Reset can be activated using an electrical switch or an input from another digital device or by a degradation of the supply voltage. The manual reset function is very useful, especially if the circuit in which the ADM811/ADM812 is operating enters into a state that can only be detected by the user. Allowing the user to reset a system manually can reduce the damage or danger that could otherwise be caused by an out-of-control or locked system.
