CAT1026ZI-30-GT3

Supervisors Overview

The CAT1026ZI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed threshold voltage of 3 V with an overvoltage threshold of 3.15 V. The device monitors a single input and provides an open-drain output without manual reset or watchdog timer functionality. It is housed in an MSOP-8 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision for CPU systems with a fixed 3 V threshold
• Features open-drain output configuration for flexible interfacing
• Operates reliably across industrial temperature ranges

Supervisors Applications

• CPU power supply monitoring
