Product details

Description

The CAT803, CAT809, and CAT810 are supervisory circuits that monitor power supplies in digital systems.The CAT803, CAT809, and CAT810 are direct replacements for the MAX803, MAX809 and MAX810 in applications operating over the industrial temperature range.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.The underlying floating gate technology
