CAT706TVI-GT3

Supervisors Overview

The CAT706TVI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed to monitor system power supplies and generate reset signals for electronic systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 4.4 V with a pull-low output configuration. The device is housed in an MSOP-8 surface-mount package and supports manual reset functionality alongside a watchdog timer. It maintains operation across an industrial temperature range from -40°C to +85°C while consuming a typical supply current of 12 µA.

Supervisors Feature Summary

• Monitors system voltage and maintains reset output until the supply reaches the specified trip value
• Includes a watchdog timer input that triggers a low signal if the monitored system signal fails to toggle before timeout
• Provides accurate brownout detection reset capabilities for various voltage systems
• Compatible with secondary low supply monitoring via the PFI input pin

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix GT3 against official datasheets to confirm the MSOP-8 packaging and tape-and-reel shipping format. Confirm the 4.4 V threshold voltage aligns with the target application requirements. Ensure the component meets RoHS compliance standards as indicated in manufacturer documentation. Cross-reference the part number with authorized distributors to validate authenticity and current availability status.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with integrated watchdog functionality is required for embedded designs. The 4.4 V threshold makes it suitable for 5 V logic systems or regulated 3.3 V rails where precise monitoring is critical. Consider the MSOP-8 package for space-constrained PCB layouts. Verify that the 12 µA quiescent current fits the power budget constraints of the portable or battery-operated application.

Supervisors Part Context

This part belongs to the CAT706 series of supervisory circuits from onsemi, which are engineered to provide reliable reset generation for digital systems. The series is functionally compatible with legacy MAX705/MAX706/MAX813L products, facilitating drop-in replacements in existing designs. These devices combine voltage monitoring with watchdog timers to enhance system reliability and fault protection in industrial and consumer electronics.

Supervisors Replacement Considerations

The CAT706SZI-GT3 is a pin and function compatible alternative within the same family. Verify that the threshold voltage and package type match the original design requirements before substitution.
