... CDELAY Figure 1. MAX6895/MAX6899 Functional Diagram Detailed Description The MAX6895–MAX6899 is a family of ultra-small, low- power, sequencing/supervisory circuits. These devices provide adjustable voltage monitoring for inputs down to 0.5V. They are ideal for use in power-supply sequenc- ing, reset sequencing, and power-switching applica- tions. Multiple devices can be cascaded for complex sequencing applications ...
