CAT1162WI-25-T3

Supervisors Overview

The CAT1162WI-25-T3 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 threshold voltage of 2.5 V with an overvoltage threshold of 2.7 V. The device provides a reset delay time of 270 ms and draws a typical operating supply current of 3 mA. It is housed in an SOIC-Wide-8 package and supports active high, active low, and open drain output types. The component includes manual reset functionality but lacks a watchdog timer or battery backup switch. It functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a 16K EEPROM for data storage alongside voltage supervision capabilities
• Provides configurable output states including active high, active low, and open drain configurations
• Includes manual reset input for system control flexibility

Supervisors Applications

• CPU power supply monitoring systems
• Embedded controller reset circuits
• Data retention management in microprocessor designs

Supervisors Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm package variant and tape/reel specifications match design requirements. Check for recent product change notifications regarding manufacturing site or material composition updates before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous voltage supervision and non-volatile data storage are required in a single package. Ensure the 2.5 V threshold aligns with the target system's minimum operating voltage. Verify that the absence of a watchdog timer meets the application's safety requirements. Consider the SOIC-Wide-8 footprint compatibility during PCB layout planning.

Supervisors Part Context

This device belongs to the CAT1162 series of supervisory circuits which combine processor reset generation with embedded EEPROM memory. The series offers various threshold voltages to accommodate different logic families. The T3 suffix indicates tape and reel packaging suitable for automated assembly processes.

Supervisors Replacement Considerations

CAT1162WI-25-GT3: Same electrical specifications with tube packaging instead of tape and reel.
