CAT1024YI-45-GT3

Supervisors Overview

The CAT1024YI-45-GT3 is a supervisory circuit integrating a 2k-bit serial EEPROM with manual reset functionality. It operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 4.5 V. The device utilizes an I²C bus interface for memory access and provides open collector/drain outputs. It includes a reset delay time of 200 ms and supports industrial temperature ranges from -40°C to +85°C. Packaged in TSSOP-8, it offers low power CMOS technology with 1 mA typical operating current.

Supervisors Feature Summary

• Integrates a 2k-bit serial EEPROM with I²C interface and system power supervisor
• Provides precision brown-out protection with manual reset input capability
• Features open drain outputs for active high or low reset signal generation

Supervisors Applications

• Microcontroller-based system memory and supervision
• Brown-out protection for ASICs and peripherals
• Data retention systems requiring manual reset control

Supervisors Procurement Notes

Verify component authenticity through authorized onsemi channels due to end-of-life status. Confirm package integrity and pin alignment against TSSOP-8 specifications. Validate datasheet revisions for electrical parameter consistency. Ensure compliance with RoHS directives before integration. Cross-reference manufacturer part numbers to avoid counterfeit substitutions.

Supervisors Selection Notes

Select this component for applications requiring combined memory storage and voltage monitoring. Verify that the 4.5 V threshold aligns with system voltage requirements. Confirm I²C bus compatibility with the host controller. Assess thermal performance within the specified operating temperature range. Evaluate manual reset necessity versus automatic watchdog alternatives.
