CAT853, CAT863 .. CAT859, CAT869 3-Pin Microprocessor Power Supply Supervisors Features - - - - - - - DESCRIPTION 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 +3.3V or 5.0V systems. The CAT859 and CAT869 feature a RESET push-pull output (active low) for the two pinout options. The CAT853 and CAT863 feature an open drain RESET output (active low)....
