LTC694IN8#PBF

Supervisors Overview

The LTC694IN8#PBF is a microprocessor supervisory circuit manufactured by Analog Devices. It operates within a supply voltage range of 3.0V to 5.5V and features a fixed threshold voltage of 4.65V with 2% accuracy. The device provides a CMOS active-low reset output, a watchdog timer function, and a battery backup switch. It includes a 200ms reset delay time and consumes 600µA of operating current. The component is housed in an 8-pin PDIP package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates power supply monitoring, reset generation, and watchdog timing functions
• Includes dedicated battery backup switch for data retention
• Provides CMOS active-low reset output signal

Supervisors Applications

• Microprocessor system supervision
• Battery backup switching circuits
• Watchdog timer implementations

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging. Confirm the manufacturer designation as Analog Devices or Linear Technology. Ensure the package type matches the required 8-pin DIP footprint. Validate the threshold voltage specification against the design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.65V threshold is required for standard logic systems. Consider the 600µA quiescent current for low-power applications. Verify that the 200ms reset delay meets the system startup timing constraints. Ensure the operating temperature range covers the intended environmental conditions.

Supervisors Part Context

This part belongs to the LTC694 family of microprocessor supervisory circuits. It shares functional similarities with the LTC694IN-3.3 but differs in threshold voltage and channel configuration. The family provides comprehensive power management solutions for embedded systems requiring reliable reset and monitoring capabilities.
