CAT1024YI-28-GT3

Supervisors Overview

The CAT1024YI-28-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 2K-bit EEPROM. It operates within a supply voltage range of 2.7 V to 5.5 V and features a manual reset input. The device provides an open collector/drain output type and includes a reset delay time of 200 ms. It does not incorporate a watchdog timer. The component is housed in a TSSOP-8 package suitable for surface mount installation. Operating temperatures range from -40°C to +85°C, with a maximum power dissipation of 1 W.

Supervisors Feature Summary

• Integrates CPU supervision functionality with non-volatile memory storage
• Supports manual reset input for system control
• Provides open collector or drain output configuration

Supervisors Applications

• CPU voltage monitoring in embedded systems
• System reset generation for microcontrollers
• Data storage in low-power electronic devices

Supervisors Procurement Notes

Verify the exact part number against official datasheets as suffixes may indicate specific packaging or temperature grades. Confirm availability status directly with the manufacturer or authorized distributors, as end-of-life notifications may affect current stock. Ensure compliance with RoHS directives and check for any recent product change notices that might impact design-in decisions.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and small data storage solution is required. Verify that the 2.7 V minimum operating voltage aligns with the system's power rails. Consider the TSSOP-8 package constraints for PCB layout. Ensure the 200 ms reset delay meets the timing requirements of the connected processor during power-up sequences.
