CBM811-3T A microprocessor monitoring circuit with logic low-level RESET output

The CBM811/CBM812 are reliable voltage monitoring devices suitable for use in most voltage monitoring applications. The CBM811/CBM812 are designed to monitor six different voltages.These voltages have been selected for the effective monitoring of 2.5 V, 3 V, 3.3 V, and 5V supply voltage levels. 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 CBM811/CBM812 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.
