CAT1024YI-30-GT3

Supervisors Overview

The CAT1024YI-30-GT3 is a supervisory circuit manufactured by onsemi, integrating a 2k-bit serial CMOS EEPROM with an I²C interface and a manual reset function. It operates within a supply voltage range of 2.7 V to 5.5 V and features a 3 V under-voltage threshold. The device includes a precision power supply monitor with a 200 ms reset delay, ensuring system stability during power transitions. Packaged in an 8-pin SOIC, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates 2k-bit serial EEPROM memory with I²C bus interface
• Provides precision power supply monitoring with brown-out protection
• Includes manual reset input for system control
• Features built-in inadvertent write protection mechanisms

Supervisors Applications

• Microcontroller-based system supervision
• Data storage in embedded systems
• Brown-out protection circuits
• Industrial control system memory backup

Supervisors Procurement Notes

Verify the specific suffix 'GT3' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead-free finish details directly with onsemi or authorized distributors. Check for any recent product discontinuance notifications or lifecycle changes that may affect long-term availability and sourcing strategies.

Supervisors Selection Notes

Select this component when a combined memory and supervision solution is required for microcontroller applications. Ensure the 3 V threshold aligns with the target system voltage requirements. Verify that the I²C interface speed and open-drain outputs are compatible with the host controller logic levels and bus configuration constraints.

Supervisors Part Context

This part belongs to the CAT1024 family of supervisory circuits, which combines EEPROM memory with voltage monitoring. It is designed for low-power CMOS applications requiring reliable data retention and system reset capabilities. The family supports various threshold voltages to accommodate different system architectures.

Supervisors Replacement Considerations

CAT1024WI-30-T3: Similar SOIC-8 package and 3V threshold but verify if the reel packaging matches requirements. CAT1024VI-30: Alternative SOIC-8 variant; confirm pinout and electrical parameter equivalence. Always validate functional compatibility with the original design before substitution.
