LTC695CN-3.3#PBF

Supervisors Overview

The LTC695CN-3.3#PBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in a 16-pin PDIP package. It provides comprehensive power management functions including a 3.3V reset threshold, battery backup monitoring, RAM write protection, power-fail alarm, and a watchdog timer. The device operates with a supply current of 600 uA and supports industrial temperature ranges.

Supervisors Feature Summary

• Integrates multiple supervisory functions into a single component for simplified design
• Provides dedicated battery backup monitoring to ensure data integrity during power transitions
• Includes hardware-based RAM write protection to prevent corruption from voltage anomalies

Supervisors Applications

• Microprocessor system power supervision
• Battery-backed memory systems
• Industrial control units requiring watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with your PCB footprint and thermal requirements. Confirm that the 3.3V threshold aligns with your target logic levels. Check for any recent product change notifications or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a complete supervisory solution is required without external discrete components. It is suitable for designs needing integrated battery backup detection and write protection alongside standard reset generation. Ensure the PDIP package fits the assembly constraints compared to surface-mount alternatives like the ISW variant.

Supervisors Part Context

This part belongs to the LTC695 series of microprocessor supervisory circuits designed by Analog Devices (formerly Linear Technology). The series focuses on providing essential power management features for embedded systems, ensuring reliable operation through integrated reset, alarm, and watchdog capabilities within a single IC package.

Supervisors Replacement Considerations

The LTC695IN-3.3#PBF offers identical electrical specifications but utilizes an SOIC-16 surface-mount package instead of the PDIP-16 form factor.
