CAT140049SWI-GT3

Supervisors Overview

The CAT140049SWI-GT3 is a supervisory circuit manufactured by onsemi, designed to monitor system voltage levels and provide reset signals. It integrates an 8k I2C serial EEPROM for non-volatile data storage. The device operates within a supply voltage range of 2.93V to 5.5V and features a threshold voltage of 2.93V. It utilizes an active low, push-pull output configuration and is housed in an 8-pin SOIC package. The component supports I2C communication with a maximum clock frequency of 0.4 MHz and offers 1 million write/erase cycles for the embedded memory.

Supervisors Feature Summary

• Integrates supervisory monitoring with embedded I2C serial EEPROM for combined reset and data retention functions
• Provides active low push-pull output for reliable microprocessor reset signaling
• Supports standard I2C interface for efficient serial data access and configuration

Supervisors Applications

• Microprocessor system supervision requiring integrated data storage
• Industrial control systems needing voltage monitoring and non-volatile parameter retention

Supervisors Procurement Notes

Verify current availability status as the component may be subject to end-of-life restrictions or limited distribution channels. Confirm package integrity and RoHS compliance upon receipt. Cross-reference ordering suffixes to ensure exact functional match with design specifications. Consult official distributor catalogs for updated lifecycle information before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a design requires both voltage supervision and small-scale non-volatile memory in a single package. Ensure the operating voltage range aligns with the target system rails. Verify that the I2C address configuration meets the bus topology requirements. Consider the thermal performance within the SOIC-8 package for the intended ambient temperature conditions.

Supervisors Part Context

This part belongs to onsemi's standard product portfolio, specifically within the supervisory circuits category. It combines power management functionality with memory capabilities, catering to designs seeking component consolidation. The series is engineered for industrial and consumer applications requiring reliable voltage monitoring alongside simple data logging or configuration storage.

Supervisors Replacement Considerations

Direct substitutes include the CAT140049TWI-GT3 variant. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement maintains the same I2C interface protocol and memory density requirements.
