... 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 ...

... CC Figure 11. Ensuring a Valid RESET Output Down to V ENSURING A VALID RESET/RESET OUTPUT DOWN TO V falls below 0.8 V, the RESET /RESET of the ADM811/ When V CC ADM812 no longer sinks current. Therefore, a high impedance CMOS logic input connected to RESET /RESET can drift to undetermined logic levels. To eliminate this problem, a 100 kΩ ...
