CAT809 - 3-Pin Microprocessor Power Supply Supervisors

Download the CAT809 datasheet PDF. This datasheet also covers the CAT803 variant, as both devices belong to the same 3-pin microprocessor power supply supervisors family and are provided as variant models within a single manufacturer datasheet.

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.

CAT803, CAT809, CAT810 3-Pin Microprocessor Power Supply Supervisors Features ■ 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, AE2(TM) used by Catalyst Semiconductor, makes it possible to offer any custom reset threshold value. Seven industry standard threshold levels are offered to support +5.0V, +3.3V, +3.0V and +2.5V systems.
