CAT1024WI-45-GT3

Supervisors Overview

The CAT1024WI-45-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 2K EEPROM. It operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 4.5 V. The device utilizes an SOIC-8 surface-mount package and provides an open collector/drain output type. It supports manual reset functionality without a watchdog timer or battery backup switch. The component ensures reliable operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates 2K EEPROM for data storage alongside voltage supervision
• Provides manual reset capability for system control
• Features open collector/drain output configuration

Supervisors Applications

Supervisors Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited distribution. Confirm RoHS compliance details through official datasheets. Check for specific ordering suffixes that may affect packaging or performance characteristics. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and non-volatile memory solution is required. The 4.5 V threshold suits standard 5 V logic systems. Consider the SOIC-8 package for space-constrained designs. Verify that the open-drain output aligns with the target microcontroller's input requirements.

Supervisors Part Context

This part belongs to the CAT1024 series of supervisory circuits from onsemi. It combines power management IC functions with EEPROM storage. The series is designed for applications requiring both system reset generation and persistent data storage in compact packages.

Supervisors Replacement Considerations

Check for direct substitutes within the CAT1024 family with different thresholds or packages. Verify pinout compatibility before replacing. Consult manufacturer documentation for any recommended upgrades or alternative parts with similar specifications.
