CAT1163WI-42-GT3

Supervisors Overview

The CAT1163WI-42-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 4.2 V with an overvoltage threshold of 4.5 V. The device provides active high, active low, and open drain outputs, includes a manual reset function, and incorporates a watchdog timer. It has a reset delay time of 270 ms and consumes 3 mA of operating current. The component is housed in an SOIC-Wide-8 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Integrates 16K EEPROM for data storage alongside CPU supervision functions
• Provides flexible output configurations including active high, active low, and open drain options
• Includes built-in watchdog timer and manual reset capability for system reliability

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Data retention applications requiring integrated non-volatile memory
• Industrial control units requiring watchdog protection

Supervisors Procurement Notes

Verify the specific suffix GT3 confirms tape and reel packaging requirements for your assembly line. Confirm RoHS compliance status through official datasheets as regulatory standards may vary by region. Check for obsolescence notices or lifecycle changes directly from onsemi before finalizing procurement plans.

Supervisors Selection Notes

Select this component when both voltage supervision and 16K EEPROM storage are required in a single package. Ensure the 4.2 V threshold aligns with your system's critical voltage levels. Verify that the SOIC-Wide-8 footprint fits your PCB layout constraints compared to standard SOIC packages.

Supervisors Part Context

This part belongs to the CAT1163 series of supervisory circuits which combine voltage monitoring with EEPROM capabilities. It is distinct from the CAT1162 series which lacks the watchdog timer and from the CAT1027 series which offers different memory sizes and input counts.

Supervisors Replacement Considerations

CAT1163WI-45-GT3 offers a higher 4.5 V threshold. CAT1163WI-30-T3 provides a 3.0 V threshold option. Verify pin compatibility and electrical specifications match your design requirements before substitution.
