CAT706SZI-GT3

Supervisors Overview

The CAT706SZI-GT3 is a microprocessor supervisory circuit manufactured by onsemi, designed to monitor system voltage and maintain a reset output until the voltage reaches the specified trip value. It features a watchdog timer with a 1.6-second timeout and secondary low supply monitoring on the PFI input. The device operates within a temperature range of -40°C to +85°C and is available in SOIC-8 and MSOP-8 packages. Key electrical parameters include a supply current of 6µA, a reset pulse width of 200ms, and guaranteed valid reset for VCC as low as 1.0V.

Supervisors Feature Summary

• Provides reset and monitoring functions for electronic systems by maintaining a reset output until system power stabilizes.
• Includes a watchdog timer function that monitors system signals and triggers a low output if the signal fails to change state before the timeout condition.
• Offers accurate brownout detection reset capabilities for 3.0, 3.6, and 5.0 volt systems.

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type (SOIC-8 or MSOP-8) matches design requirements. Check datasheet revisions for any updates to electrical characteristics or pin configurations. Ensure compliance with RoHS standards as indicated in official documentation. Validate operating temperature range suitability for the intended application environment.

Supervisors Selection Notes

Select this component when precise voltage monitoring and watchdog functionality are required for embedded systems. Consider the 6µA supply current for low-power applications. Evaluate the 200ms reset pulse width against system startup timing requirements. Compare pin compatibility with MAX705/MAX706/MAX813L if migrating from legacy designs. Assess package options based on PCB space constraints.

Supervisors Part Context

The CAT706 series belongs to onsemi's lineup of microprocessor supervisory circuits, providing essential reset and monitoring functions. These devices are engineered to ensure system reliability by detecting voltage anomalies and managing reset states. The series supports various voltage levels and includes watchdog timers for enhanced fault detection, making them suitable for critical electronic applications requiring stable power management.

Supervisors Replacement Considerations

The CAT706SZI-GT3 is pin and function compatible with MAX705, MAX706, and MAX813L products. Verify electrical specifications and package dimensions before substituting with these equivalents. Ensure the alternative part meets the required operating temperature range and supply current constraints.
