CAT1162WI-25-GT3

Supervisors Overview

The CAT1162WI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision with integrated 16K EEPROM. It operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 2.5 V. The device provides manual reset functionality with a reset delay time of 270 ms. It supports active high, active low, and open drain output types. Operating temperatures range from -40°C to +85°C. The component is housed in an SOIC-Wide-8 package and consumes 3 mA of operating current.

Supervisors Feature Summary

• Integrates 16K EEPROM for data storage alongside voltage supervision
• Provides manual reset capability with configurable output types
• Operates across a wide industrial temperature range

Supervisors Applications

• CPU power supply monitoring systems
• Embedded controller supervision circuits
• Industrial control board voltage tracking

Supervisors Procurement Notes

Verify the specific suffix 'GT3' against official onsemi documentation to confirm tape-and-reel packaging specifications. Confirm that the 'WI' designation aligns with the required SOIC-Wide-8 package variant. Check for end-of-life status or obsolescence notices prior to procurement planning. Ensure compatibility with existing PCB footprints for the specified package type.

Supervisors Selection Notes

Select this component when simultaneous voltage supervision and non-volatile data storage are required in a single package. The 2.5 V threshold suits applications monitoring lower voltage rails. Consider the 3 mA quiescent current if power efficiency is critical compared to lower-power alternatives. Verify that the manual reset feature meets system safety requirements without additional external components.

Supervisors Part Context

This part belongs to the CAT1162 series of supervisory circuits which combine voltage monitoring with embedded memory. It serves as a specialized solution for microcontroller systems needing both power integrity checks and configuration data retention. The series typically offers various threshold options and package configurations to suit different design constraints.
