CAT1161WI-25-T3

Supervisors Overview

The CAT1161WI-25-T3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 16k EEPROM within the supervisory logic. The device operates in an SOIC-Wide-8 surface-mount package and features a threshold voltage of 2.5 V. It supports active high, active low, and open drain output types with manual reset capability. The component monitors a single input and functions within a specified temperature range.

Supervisors Feature Summary

• Integrates non-volatile 16k EEPROM storage alongside voltage supervision logic
• Provides configurable output states including active high, active low, and open drain configurations
• Supports manual reset functionality for system control

Supervisors Applications

• CPU power supply monitoring
• Embedded system voltage supervision
• Data retention management via integrated EEPROM

Supervisors Procurement Notes

Verify current availability status as the component is listed as end-of-life or discontinued by major distributors. Confirm specific ordering suffixes match required package and tape/reel specifications. Check for valid RoHS compliance documentation before integration into new designs due to potential supply chain constraints.

Supervisors Selection Notes

Select this component when simultaneous voltage supervision and persistent data storage are required in a compact footprint. Ensure the 2.5 V threshold aligns with the target system's operating voltage levels. Consider the SOIC-Wide-8 package dimensions for PCB layout compatibility and verify that manual reset requirements fit the system architecture.

Supervisors Part Context

This part belongs to the CAT1161 series of supervisory circuits from onsemi, which combine power management monitoring with memory functions. The series targets applications requiring reliable system reset mechanisms and configuration data storage. It falls under the broader category of PMIC supervisory ICs designed for industrial and consumer electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the CAT1161 family with different threshold voltages if system voltage levels differ. Verify functional equivalence regarding EEPROM capacity and output drive capabilities when evaluating alternative vendors.
