LTC694CS8#TRPBF

Supervisors Overview

The LTC694CS8#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages in microprocessor systems. It operates within a supply voltage range of 3 V to 5.5 V and features a fixed threshold voltage of 4.65 V with 2% accuracy. The device includes a watchdog timer, battery backup switch, and chip enable functionality. It draws 600 uA of operating current and dissipates up to 500 mW of power. Packaged in an SOIC-8 surface-mount format, it functions reliably between 0°C and +70°C.

Supervisors Feature Summary

• Integrated watchdog timer for system fault detection
• Battery backup switch capability for data retention
• Chip enable input for low-power management

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Battery-backed memory protection circuits

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. or Linear Technology. Ensure the package type matches SOIC-8 requirements for your PCB layout. Check RoHS compliance status through official documentation before integration.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for single-input monitoring. Consider the 600 uA quiescent current against system power budgets. Verify that the SOIC-8 package fits the available footprint. Ensure the operating temperature range of 0°C to +70°C meets environmental specifications.

Supervisors Part Context

This part belongs to the LTC694 series of supervisory circuits from Analog Devices. It is functionally similar to the LTC694CS8-3.3#PBF but utilizes a different threshold voltage configuration. The series provides essential reset and monitoring functions for digital logic systems without requiring external components for basic operation.

Supervisors Replacement Considerations

The LTC694CS8-3.3#PBF serves as a related variant within the same family, offering a different threshold voltage. Cross-reference datasheets to confirm pin compatibility and electrical parameter alignment before substitution.
