... The manual reset function is very useful, especially if the circuit in which the ADM811/ADM812 are 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 ...

... This allows time for the power supply and microprocessor to stabilize. The ADM811 provides an active low reset output ( RESET ) while the ADM812 provides an active high output (RESET). During power-down of the ADM811, the RESET output remains valid (low) with V the microprocessor is held in a stable shutdown condition as the supply falls and also ensures that no spurious activity can occur via the microprocessor as it powers up ...

... ADM811/ADM812 INTERFACING TO OTHER DEVICES OUTPUT The ADM811/ADM812 are designed to integrate with as many devices as possible. One feature of the ADM811/ADM812 is the reset output, which is directly proportional to V anteed only while V is greater than 1 V). This enables the part used with both 3 V and any nominal voltage within ...
