CAT1026YI-30-GT3

Supervisors Overview

The CAT1026YI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 2-kbit CMOS EEPROM with I²C serial interface capabilities within a single package. The device operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 3 V. It supports SMD/SMT installation in an MSOP-8 package. Key electrical parameters include a maximum power dissipation of 1 W, an operating current of 3 mA, and an overvoltage threshold of 3.15 V. The component functions without manual reset or watchdog timer features and is rated for industrial temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates dual functionality as a voltage supervisor and non-volatile memory controller
• Utilizes I²C serial interface for data communication with the EEPROM
• Provides hardware-based system reset generation upon voltage deviation

Supervisors Applications

• CPU supervision in embedded systems requiring voltage monitoring
• Data storage and retrieval in portable electronic devices
• Industrial control systems needing reliable power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status via official datasheets before integration. Check for obsolescence notices as this series may have discontinuation updates. Ensure packaging specifications match assembly requirements. Validate temperature ratings against operational environment constraints.

Supervisors Selection Notes

Select this component when both voltage supervision and small-scale data storage are required in a compact form factor. Consider the MSOP-8 package size for space-constrained designs. Verify that the 3V threshold aligns with the target system's voltage levels. Evaluate the I²C interface compatibility with existing microcontrollers. Assess power consumption requirements against the 3mA operating current specification.

Supervisors Part Context

This part belongs to the CAT1026 series of supervisory circuits produced by onsemi. The series combines voltage monitoring with integrated EEPROM functionality. Similar variants exist with different package types such as SOIC-8 and PDIP-8, and varying threshold voltages. The manufacturer provides comprehensive documentation including datasheets and ECAD models for design support.

Supervisors Replacement Considerations

CAT1026WI-30-T3 offers identical electrical characteristics in an SOIC-8 package instead of MSOP-8. CAT1026ZI-30-T3 provides the same functionality in an MSOP-8 package with reel packaging. Verify pinout compatibility and thermal performance when substituting these alternatives.
