CAT1026YI-42-GT3

Supervisors Overview

The CAT1026YI-42-GT3 is a dual voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates an I2C serial 2k-bit CMOS EEPROM within the package. The device operates with a maximum supply voltage of 5.5 V and features a threshold voltage of 4.2 V. It utilizes a TSSOP-8 surface-mount package and supports a manual reset function without a watchdog timer. The component functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual voltage supervision capability for critical system monitoring
• Integrated I2C serial 2k-bit CMOS EEPROM for data storage
• Manual reset functionality for user-initiated system recovery

Supervisors Applications

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

Supervisors Procurement Notes

Verify current availability status as this component may be subject to specific ordering requirements or lifecycle restrictions. Confirm package type and electrical parameters against the official datasheet before integration. Ensure compatibility with existing PCB footprints and design specifications. Contact authorized distributors for precise procurement details and lead times.

Supervisors Selection Notes

Select this component when dual voltage supervision combined with non-volatile memory storage is required. The integrated EEPROM allows for configuration data retention during power cycles. Verify that the 4.2 V threshold aligns with the target system's voltage levels. Consider the TSSOP-8 package constraints for board layout and thermal management requirements.

Supervisors Part Context

This part belongs to the CAT1026 series of supervisory circuits from onsemi. These devices are engineered to provide reliable power management solutions for embedded systems. The series combines voltage monitoring with data storage capabilities, offering a compact solution for applications requiring both system integrity checks and persistent memory access.

Supervisors Replacement Considerations

CAT1026WI-42-GT3: Similar supervisory circuit with SOIC-8 package instead of TSSOP-8. Verify pinout compatibility and package dimensions before substitution.
