The LTC692IS8#PBF is a high-performance microprocessor supervisory circuit designed by Linear Technology, now part of Analog Devices, to ensure reliable operation of microprocessor systems during power failures. This essential component provides a precise monitoring solution for microprocessor (µP) systems, by monitoring the power supply voltage and maintaining a reset output active as long as the supply voltage remains below a designated threshold.

Key Features

• Precision Voltage Monitoring: The LTC692IS8#PBF is equipped to monitor 5V, 3.3V, and other voltage levels with a high degree of accuracy, ensuring that the µP and other logic circuits are reset accurately and reliably.
• Low Power Consumption: This device is designed for systems where power efficiency is critical, consuming only a small amount of power to carry out its supervisory functions.
• Reset Timeout Delay: It features an adjustable reset timeout delay, which provides flexibility in determining how long the system should remain in reset condition after a power failure.
• Manual Reset Capability: A manual reset input allows for a system reset to be triggered by external events or user intervention, adding an extra layer of control.
• Wide Operating Temperature Range: The LTC692IS8#PBF is designed to operate over a wide temperature range, making it suitable for use in various environments and applications.

Applications

This supervisory circuit is ideal for use in microprocessor systems, portable electronics, computers, controllers, and other digital systems that require reliable operation and an intelligent power monitoring system. Its robustness and precision make it a go-to choice for critical applications where system integrity cannot be compromised.

Package Information

The LTC692IS8#PBF comes in a narrow 8-lead SOIC package, which is compact and suitable for space-constrained applications. Its part number suffix 'PBF' indicates that it is a lead-free ("Pb-free") and RoHS-compliant component, reflecting Linear Technology's commitment to environmental responsibility.

Conclusion

Overall, the LTC692IS8#PBF by Linear Technology is a reliable and efficient solution for system voltage monitoring and reset management. It ensures that microprocessor-based systems remain functional and safe in the event of power anomalies, thus preserving data integrity and preventing system failures.
