Product Summary
The MAX824SEUK+T microprocessor (μP) supervisory circuit combines reset output, watchdog, and manual-reset input functions in a 5-pin SOT23-5 package. It significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX824SEUK+T is specifically designed to ignore fast transients on VCC. Five preprogrammed reset threshold voltages are available, designated by the following package suffixes: L = 4.63V, M = 4.38V, T = 3.08V, S = 2.93V, and R = 2.63V. The MAX824SEUK+T has an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. The MAX824SEUK+T also has an active-high reset output.
