CAT1022YI-30-GT3

Supervisors Overview

The CAT1022YI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring system power integrity. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed under-voltage threshold of 3.0 V. The device provides manual reset functionality with a standard reset delay time of 200 ms. It utilizes an open collector or drain output type and is housed in an 8-pin TSSOP package suitable for surface mount applications. The component supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage supervision with manual reset control for reliable system management
• Features open collector/drain output configuration for flexible interface compatibility
• Supports operation across a wide industrial temperature range for robust performance

Supervisors Applications

• CPU voltage supervision in embedded systems
• Power management circuits requiring manual reset capability
• Industrial control boards operating within specified voltage limits

Supervisors Procurement Notes

Verify the specific suffix 'GT3' against official onsemi documentation to confirm tape and reel packaging specifications. Confirm that the 'I' designation accurately reflects the industrial temperature grade requirements for your application environment. Ensure the TSSOP-8 footprint matches your PCB design constraints before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.0 V under-voltage threshold is required for system monitoring. Consider the 200 ms reset delay duration to ensure it aligns with the startup timing requirements of the controlled logic. Verify that the open-drain output architecture is compatible with the pull-up resistor configuration used in the target circuit design.
