CAT1024LI-30

Supervisors Overview

The CAT1024LI-30 is a supervisory circuit integrating a 2k-bit serial EEPROM and a voltage monitor in an SOIC-8 package. It operates within a supply voltage range of 2.7 V to 5.5 V with a threshold voltage of 3 V. The device features manual reset capability, supports I²C communication at 400 kHz, and includes a 16-byte page write buffer. It functions across temperatures from -40°C to +85°C, drawing 3 mA during operation.

Supervisors Feature Summary

• Integrates 2k-bit serial EEPROM memory with system power supervisor for microcontroller-based applications
• Provides brown-out protection via precision voltage monitoring with active high or low reset outputs
• Includes built-in inadvertent write protection and supports 1,000,000 program/erase cycles

Supervisors Applications

• Microcontroller system memory backup
• Brown-out protection circuits
• I²C bus data storage systems

Supervisors Procurement Notes

Verify the specific suffix 'LI' against official onsemi documentation to confirm lead frame material and package variant. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for end-of-life notices or alternative recommendations directly from the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a combined memory and supervision solution is required for 3 V systems. Ensure the I²C interface compatibility matches the host controller. Verify that the 3 V threshold aligns with the target application's voltage tolerance requirements and that the industrial temperature range meets environmental specifications.

Supervisors Part Context

Part of the CAT1024/CAT1025 family offering integrated EEPROM and supervisory functions. The CAT1024 variant specifically lacks the write protect pin found in the CAT1025 model. This series addresses space-constrained designs by combining two distinct components into a single low-power CMOS package.

Supervisors Replacement Considerations

CAT1024WI-30-T3 offers similar functionality in an SOIC-8 surface mount package with reel packaging.
