Linear Technology LTC691CSN Microprocessor Supervisory Circuit

The LTC691CSN from Linear Technology is a sophisticated microprocessor supervisory circuit designed to manage power supply and system reset operations in microprocessor-based systems. With its precise monitoring and control capabilities, this device ensures that your system operates reliably within its intended parameters.

Key Features

• Voltage Monitoring: The LTC691CSN provides accurate monitoring of the power supply voltage levels, ensuring the microprocessor has a stable voltage to operate. It is capable of monitoring 5V, 3.3V, and adjustable voltage options.
• Reset Output: Upon detecting an out-of-tolerance condition, the device generates a reset signal to the microprocessor. The reset signal is maintained for a period after the voltage returns to an acceptable level, ensuring the system has stabilized before normal operation resumes.
• Watchdog Timer: An onboard watchdog timer improves system reliability by resetting the microprocessor if it fails to stroke the watchdog within a preset time window. This feature helps in recovering from software lock-up conditions.
• Low Power Consumption: The LTC691CSN is designed for low power consumption, making it an ideal choice for battery-operated systems where power efficiency is critical.
• Compact Package: Housed in a narrow 16-pin SOIC package, the LTC691CSN saves precious board space and is suitable for space-constrained applications.
