The LTC695IN is a robust microprocessor supervisory circuit designed by Linear Technology, a company renowned for its high-performance analog integrated circuits. This device is engineered to maintain system integrity by monitoring the power supply voltage in microprocessor systems, offering a reliable solution for system reset and backup battery switchover operations.

Key Features

• Precision Voltage Monitoring: The LTC695IN is equipped with a precise voltage monitor that keeps a vigilant watch on the power supply levels, ensuring that the microprocessor and associated circuitry have a stable and adequate voltage for operation.
• Power Fail Warning: To prevent data loss and system errors, the device provides an early warning signal when the power supply falls below a predefined threshold, allowing the system to take corrective action before a complete power failure occurs.
• Low Battery Detection: This feature alerts the system when the backup battery is nearing depletion, facilitating timely battery replacement or charging to avoid system downtime.
• Reset Output: In the event of an undervoltage condition, the LTC695IN generates a reset signal that can be used to reboot the microprocessor, ensuring that the system restarts with a clean state once normal voltage levels are restored.
• Backup Battery Switchover: The device includes an automatic switchover to a backup battery when the primary power supply fails, allowing critical system functions to continue without interruption.
