LTC699IN8 Microprocessor Supervisory Circuit

The LTC699IN8 is a precision microprocessor supervisory circuit designed by Linear Technology to enhance the reliability and robustness of electronic systems. This compact and efficient component is engineered to monitor the power supply and microprocessor activity in digital systems, ensuring that these systems operate within their specified voltage thresholds and providing a controlled environment for the microprocessor to initialize.

Key Features

• Power Supply Monitoring: The LTC699IN8 vigilantly monitors the power supply voltage. It guarantees that the voltage levels are within acceptable limits to prevent any damage to the microprocessor and associated circuitry.
• Reset Output: In the event of a power failure or an unacceptable voltage drop, the device generates a reset signal. This reset output remains active for a period after the voltage returns to a safe level, ensuring the system has stabilized before normal operation resumes.
• Low Power Consumption: With its focus on energy efficiency, the LTC699IN8 draws minimal power from the system, making it ideal for battery-operated and portable applications.
• Manual Reset Input: The inclusion of a manual reset input provides an additional layer of control, allowing for a system reset to be triggered manually when required.
• Debounced TTL/CMOS Compatible Manual Reset Input: The manual reset input is debounced, ensuring that only clean and noise-free signals trigger a reset.
• Watchdog Timer: An onboard watchdog timer helps to detect and recover from software failures. If the microprocessor fails to provide a periodic signal to the watchdog timer, a reset signal will be issued.
• Temperature Range: The LTC699IN8 is designed to operate over a wide temperature range, making it suitable for industrial applications.

Applications

The LTC699IN8 is versatile and can be used across a wide variety of applications. It is particularly suited for use in:

• Microprocessor systems
• Computers and controllers
• Portable and battery-powered equipment
• Intelligent instruments
• Automotive systems

With its robust feature set, the LTC699IN8 from Linear Technology is an essential component for any system that requires reliable voltage monitoring and microprocessor supervision. Its small footprint and low power consumption make it an excellent choice for designers looking to enhance system integrity without compromising on performance or space.
