Description

General part information

CAT853 Series

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 aRESETpush-pull output (active low) for the two pinout options.The CAT853 and CAT863 feature an open drain RESET output (active low). Both require a pull-up resistor on theRESEToutput.Fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at VCC levels as low as 1.0 V.
