CAT1162WI-28-GT3

Supervisors Overview

The CAT1162WI-28-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 2.7 V to 6 V and features a fixed threshold voltage of 2.8 V. The device provides a reset delay time of 270 ms and supports manual reset functionality. It is available in an SOIC-8 surface-mount package and functions across an industrial temperature range from -40°C to +85°C. The component draws a typical operating current of 3 mA and includes open-drain output capabilities.

Supervisors Feature Summary

• Integrates voltage supervision with 16K EEPROM memory for system data retention
• Supports manual reset input for user-initiated system recovery
• Provides flexible output configurations including active high, active low, and open drain options

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Data storage backup management using integrated EEPROM
• Industrial control units requiring manual reset capability

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as the provided model uses GT3 while source data references T3 variants. Confirm availability status as the product may be discontinued or subject to allocation restrictions. Ensure the SOIC-8 package and 2.8 V threshold match design requirements before procurement.

Supervisors Selection Notes

Select this component when both voltage supervision and non-volatile data storage are required in a single package. The 2.8 V threshold suits 3.3 V logic systems. Verify that the 270 ms reset delay meets system startup timing constraints. Consider the manual reset feature if external user intervention is necessary for system recovery.

Supervisors Part Context

This part belongs to the CAT1162 series of supervisory circuits combining voltage monitoring with EEPROM storage. It serves as a compact solution for systems needing both power integrity checks and persistent data retention without requiring separate components.
