CAT1640WI-25-GT3

Supervisors Overview

The CAT1640WI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supply monitoring. It operates within a supply voltage range of 2V to 7V and features a fixed threshold of 2.55V. The device provides manual reset capability with a reset delay time of 5 microseconds. It utilizes an open collector/drain output type and supports two monitored inputs. The component is housed in an SOIC-Wide-8 package suitable for surface mount installation. It functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated manual reset functionality for system control
• Dual input voltage supervision capability
• Open collector or drain output configuration

Supervisors Applications

• CPU power supply monitoring
• Voltage supervision in embedded systems
• Manual reset generation in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix GT3 against current manufacturer documentation to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status through official datasheets as regulatory requirements may vary by region. Ensure the SOIC-Wide-8 footprint matches the target PCB design constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when dual-input voltage supervision is required alongside manual reset capabilities. The fixed 2.55V threshold suits applications where precise low-voltage detection is necessary without adjustable potentiometers. Consider the open-drain output compatibility with downstream logic levels and verify that the 5us reset delay meets the system timing requirements.

Supervisors Part Context

This part belongs to the CAT1640 series of voltage supervisors from onsemi. It shares architectural similarities with other parts in the family but is distinguished by its specific threshold voltage and manual reset feature. The WI-25 designation indicates the wide SOIC package and specific electrical characteristics defined by the manufacturer's standard nomenclature.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and threshold voltage accuracy if considering alternative manufacturers' devices for direct replacement.
