LTC694IN8-3.3#PBF

Supervisors Overview

The LTC694IN8-3.3#PBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in an 8-pin PDIP package. It functions as a power supply management device with a fixed reset threshold voltage of 3.3V. The component supports a single active-low output and operates within a temperature range of -40°C to +85°C. Designed for reliability, it includes features such as manual reset capability and watchdog timer functionality to ensure system integrity during voltage fluctuations or software faults.

Supervisors Feature Summary

• Provides precise supervision of power supply voltages with a factory-set 3.3V threshold
• Integrates manual reset input for controlled system initialization
• Includes watchdog timer functionality to detect and recover from software errors
• Delivers active-low reset signal for reliable processor monitoring

Supervisors Applications

• Microprocessor system power monitoring
• Embedded controller reset management
• Industrial equipment voltage supervision
• Automotive electronics power integrity checks

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the PDIP-8 package type matches your PCB footprint requirements. Check current availability status as distribution may vary. Ensure the 3.3V threshold aligns with your target logic levels. Validate operating temperature range suitability for your environment.

Supervisors Selection Notes

Choose this part when a fixed 3.3V supervision threshold is required without external resistor programming. Select for applications needing integrated watchdog and manual reset in a compact DIP package. Consider if the active-low output polarity fits your design. Evaluate thermal performance within the specified industrial temperature range.

Supervisors Part Context

This component belongs to the LTC694 family of supervisory circuits designed for robust power management. It complements other Analog Devices PMIC solutions by offering dedicated voltage monitoring.
