Power Supply Supervisors

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 +3.3 V or

5.0 V 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). Both require a pull−up resistor on the RESET output.

Fast transients on the power supply are ignored and the output is
