CAT1026WI-45-GT3

Supervisors Overview

The CAT1026WI-45-GT3 is a dual voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 2k-bit CMOS EEPROM with I2C serial interface capabilities within an SOIC-Wide-8 package. The device operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 4.5 V. It supports active high, active low, open drain, and CMOS output types. The component functions without manual reset or watchdog timer features, ensuring reliable power management in industrial and consumer electronics environments.

Supervisors Feature Summary

• Integrates dual voltage supervision with a 2k-bit I2C serial EEPROM for data retention
• Supports multiple output configurations including active high, active low, open drain, and CMOS
• Operates reliably across extended temperature ranges from -40°C to +85°C

Supervisors Applications

• CPU voltage monitoring in embedded systems
• Industrial control system power management
• Consumer electronics power supply supervision

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape and reel packaging when sourcing this component. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-Wide-8 footprint matches your PCB design requirements. Check current lifecycle status as distribution availability may vary by region.

Supervisors Selection Notes

Select this part when dual voltage supervision combined with non-volatile memory storage is required. The I2C interface allows for efficient communication with microcontrollers. Consider the 4.5V threshold specifically for 5V logic systems. Verify that the absence of a watchdog timer meets your system safety requirements.

Supervisors Part Context

This component belongs to the CAT1026 series of supervisory circuits from onsemi. The series provides integrated power management solutions combining voltage monitoring with EEPROM storage. The WI-45 designation specifies the wide SOIC package and 4.5V threshold variant within this product family.

Supervisors Replacement Considerations

CAT1026WI-45-G is available as a tube-packaged alternative with identical electrical specifications. CAT1026ZI-45-T3 offers the same functionality in an MSOP-8 package for space-constrained designs.
