CAT1026LI-30-G

Supervisors Overview

The CAT1026LI-30-G 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 includes a 2K-bit CMOS EEPROM for data storage and utilizes the I²C bus interface. It is housed in an 8-pin PDIP package suitable for through-hole mounting. The component supports industrial temperature ranges from -40°C to +85°C and consumes 3 mA of operating current.

Supervisors Feature Summary

• Integrates dual voltage supervision with reset output generation to protect systems during power anomalies
• Includes serial 2k-bit CMOS EEPROM with hardware write protection mechanisms
• Supports I²C communication interface for reliable data access

Supervisors Applications

• CPU system monitoring
• Voltage supervision in embedded controllers
• Data retention in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and confirm the 'LI' designation corresponds to the PDIP-8 through-hole package variant. Ensure the '30' suffix matches the required 3V threshold for your design. Cross-reference the manufacturer's latest datasheet revision to confirm active status and any pinout updates before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a through-hole solution is required for voltage supervision combined with non-volatile memory storage. The 3V threshold makes it suitable for 3.3V or 3V logic systems. Consider the PDIP-8 package constraints regarding PCB space and thermal dissipation compared to surface-mount alternatives like SOIC or TSSOP variants within the same series.

Supervisors Part Context

This part belongs to the CAT1026 series of dual voltage supervisory circuits with integrated I²C serial EEPROM. The series provides robust power management solutions for microprocessor systems. The LI-30-G variant specifically denotes the through-hole PDIP package, 3V threshold, and lead-free construction, distinguishing it from surface-mount or different threshold options in the broader product family.

Supervisors Replacement Considerations

Check for CAT1026WI-30-G for a surface-mount SOIC alternative with identical electrical characteristics. Verify CAT1026PI-30 if a legacy PDIP version without the green (lead-free) suffix is acceptable. Ensure substitute parts maintain the same I²C addressability and EEPROM capacity.
