CAT1026WI-28-GT3

Supervisors Overview

The CAT1026WI-28-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 2-kilobit EEPROM within the supervisory logic. The device operates with a single monitored input and features an active high, active low, or open drain output configuration. Key electrical parameters include a threshold voltage of 2.8 V, a reset delay time of 200 ms, and a maximum supply voltage of 5.5 V. It utilizes a SOIC-wide-8 surface mount package and supports operation down to -40°C.

Supervisors Feature Summary

• Integrates 2-kilobit EEPROM with voltage supervisory logic
• Provides flexible output options including active high, active low, and open drain
• Designed for single-input CPU power monitoring applications

Supervisors Applications

• CPU power supply supervision
• Embedded system voltage monitoring
• Data retention management via integrated EEPROM

Supervisors Procurement Notes

This component has reached end-of-life status and will be discontinued by the manufacturer. Procurement should focus on verifying final availability through authorized channels or exploring qualified replacement alternatives. Verify RoHS compliance details and confirm package specifications against current design requirements before ordering.

Supervisors Selection Notes

Select this part when a combined supervisory function and non-volatile data storage are required in a compact form factor. Ensure the 2.8 V threshold aligns with the target system voltage. Consider the 200 ms reset delay timing constraints and verify that the SOIC-wide-8 package fits the PCB layout. Evaluate lifecycle status due to discontinuation.

Supervisors Part Context

Part of the CAT1026 series from onsemi, which combines voltage monitoring with embedded memory. This specific variant uses a 2.8 V threshold and wide-body packaging. The series targets applications needing both system integrity checks and small-scale data logging without external components.
