LTC692CN8#PBF

Supervisors Overview

The LTC692CN8#PBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc. in an 8-pin PDIP package. It provides essential system protection functions including a programmable watchdog timer, a manual reset input, and a voltage monitor with selectable thresholds. The device operates within a supply voltage range of 1.7V to 5.5V and features a low-power CMOS design suitable for battery-operated applications.

Supervisors Feature Summary

• Integrates a watchdog timer with a timeout period adjustable via external components
• Includes a manual reset input for initiating system resets on demand
• Features a voltage monitor with selectable threshold voltages for power supervision

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the specific suffix CN8 corresponds to the PDIP-8 package and commercial temperature range when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the part number matches the exact supervisory requirements before procurement.

Supervisors Selection Notes

Select this component when a combined watchdog, manual reset, and voltage monitor solution is required in a single package. Evaluate the available threshold options against the target supply voltage rails. Consider the PDIP-8 package constraints if surface-mount space is limited but through-hole assembly is preferred.

Supervisors Part Context

This part belongs to the LTC690 series of microprocessor supervisory circuits from Analog Devices. It serves as a comprehensive protection IC for embedded systems, replacing discrete logic solutions. The series includes variants with different packages and fixed thresholds to suit various design architectures.

Supervisors Replacement Considerations

Compatible alternatives include the ADM690A and MAX690A. Verify pin compatibility and threshold voltage specifications before substitution. Check for any differences in watchdog timeout accuracy or operating temperature ranges.
