LTC695CN-3.3#PBF

Supervisors Overview

The LTC695CN-3.3#PBF is a microprocessor supervisory circuit manufactured by Analog Devices (formerly Linear Technology). It provides a reset signal for systems operating at 3.3V. The device features an open-drain or open-collector output and operates within a supply voltage range of 1.2V to 5.5V. It includes a manual reset input and a watchdog timer function. The component is available in an 8-pin PDIP package.

Supervisors Feature Summary

• Provides reliable system reset for microprocessors and digital controllers
• Integrates a watchdog timer with programmable timeout period
• Includes a manual reset input for external control capability

Supervisors Applications

• Microprocessor power supply monitoring
• Digital controller system supervision
• Embedded system reset generation

Supervisors Procurement Notes

Verify the manufacturer designation, as Analog Devices acquired Linear Technology. Confirm the specific suffix indicates the correct package type and temperature rating. Ensure the part number matches the required 3.3V threshold specification for your application design.

Supervisors Selection Notes

Select this component when a fixed 3.3V reset threshold is required for low-voltage digital systems. Consider the PDIP package constraints for prototyping versus surface-mount alternatives. Evaluate the need for the integrated watchdog timer against external timing requirements.

Supervisors Part Context

This part belongs to the LTC695 series of supervisory circuits designed for monitoring power rails in embedded applications. It serves as a fundamental protection component ensuring system stability during power-up and brown-out events.

Supervisors Replacement Considerations

Compatible substitutes include ADM690A and MAX690 from other manufacturers offering similar supervisory functions. Verify pin compatibility and threshold voltage accuracy before substitution.
