CAT1026WI-30-GT3

Supervisors Overview

The CAT1026WI-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 threshold voltage of 3 V with an overvoltage threshold of 3.15 V. The device monitors a single input and does not include manual reset or watchdog timer functions. It consumes 3 mA of operating current and dissipates up to 1 W of power. The component is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage supervision with 2K EEPROM storage capabilities
• Provides active high, active low, and open drain output options
• Supports CMOS logic interface compatibility

Supervisors Applications

• CPU system monitoring
• Voltage supervision in embedded systems
• Data retention management via integrated EEPROM

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the manufacturer part number matches exactly to avoid pinout or functional mismatches. Check for any recent product change notices affecting availability or specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a combined supervisor and non-volatile memory solution is required in a compact SOIC-8 package. The 3V threshold suits 3.3V logic systems. Verify that the absence of a watchdog timer meets system safety requirements. Consider the 2K EEPROM capacity against application data storage needs.

Supervisors Part Context

This part belongs to the CAT1026 series of supervisory circuits from onsemi. It combines power management IC functionality with EEPROM storage. The WI-30 designation specifies the wide-body SOIC package and 3V threshold variant. The GT3 suffix typically denotes reel packaging for automated assembly processes.

Supervisors Replacement Considerations

CAT1026WI-30-G is a compatible tube-packaged alternative from the same series.
