CAT705VI-GT3

Supervisors Overview

The CAT705VI-GT3 is a microprocessor supervisory circuit manufactured by onsemi, designed to monitor system voltage and ensure reliable reset generation. It provides a guaranteed valid reset output starting from 1.0 V supply voltage. The device features a low supply current of 6 µA and a fixed 200 ms reset pulse width. It includes an accurate brownout detection function for 3.0, 3.6, and 5.0 volt systems, along with a secondary low-supply monitoring input. The component operates within a temperature range of -40°C to +85°C and is available in SOIC-8 and MSOP-8 packages.

Supervisors Feature Summary

• Monitors system voltage and maintains reset output until the specified trip value is reached
• Includes a watchdog timer function with a 1.6-second timeout period
• Provides accurate brownout detection reset for standard voltage systems
• Features a secondary low-supply monitoring input on the PFI pin

Supervisors Applications

• Microprocessor and microcontroller based systems
• Instrument and control systems
• Portable equipment

Supervisors Procurement Notes

Verify that the specific suffix GT3 corresponds to the tape and reel packaging format required for your assembly line. Confirm the package type matches your PCB footprint requirements, as this series is available in both SOIC-8 and MSOP-8 configurations. Ensure the operating voltage range aligns with your system's power supply specifications before finalizing the procurement order.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit is needed for systems requiring a guaranteed reset at voltages as low as 1.0 V. It is suitable for designs needing a fixed 200 ms reset pulse and a 1.6 s watchdog timeout. Consider the secondary monitoring input if additional voltage supervision is required beyond the main VCC rail.

Supervisors Part Context

The CAT705VI-GT3 belongs to the CAT705/CAT706/CAT813 family of microprocessor supervisory circuits. These devices are pin and function compatible with MAX705/MAX706/MAX813L products, facilitating direct replacements in existing designs. The family focuses on providing reliable reset and monitoring functions for electronic systems across industrial and consumer applications.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include CAT705ZI-GT3 and CAT706VI-GT3. These components share similar supervisory functions and pin compatibility. Verify specific voltage thresholds and package availability when substituting to ensure design continuity.
