The CAT853, CAT863, CAT859, and CAT869 are supervisory circuits that monitor power supplies in digital systems.These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140 ms after the power supply level has risen above that level.Industry standard threshold levels are offered to support +3.3 V or 5.0 V systems.The CAT859 and CAT869 feature a RESET push pull output (active low) for the two pinout options
