Description:

Dual voltage supervisory circuits.

CAT1026, Dual Voltage Supervisory Circuits

The CAT1026 and CAT1027 are complete memory and supervisory solutions for microcontroller-based systems.

A 2k-bit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS techno * logy.

Memory interface is via a 400kHz I2C bus.

The

CAT1026 Features

* Precision VCC Power Supply Voltage Monitor

* 5V, 3.3V and 3V systems

* Five threshold voltage options Additional voltage monitoring

* Externally adjustable down to 1.25V Watchdog timer (CAT1027 only) Active High or Low Reset

* Valid reset guaranteed at VCC = 1V 400kHz
