LTC1232CS8#TR Microprocessor Supervisory Circuit
The LTC1232CS8#TR is a state-of-the-art microprocessor supervisory circuit designed by Linear Technology to ensure reliable operation of microprocessor (µP) systems. It offers a robust set of features aimed at providing system stability during power-up, power-down, and brownout conditions. Its compact surface-mount package, specifically the 8-lead SOIC, makes it suitable for space-constrained applications.
Key Features:
- Power Monitoring: The LTC1232CS8#TR actively monitors the power supply voltage and keeps the microprocessor in the reset state until stable power is guaranteed. This feature ensures that the µP and its peripherals are reset together when power is applied.
- Automatic Reset Generation: Upon detecting a power fault, the device generates an automatic reset pulse to reset the microprocessor without the need for external components.
- Reset Timeout: It features an adjustable reset timeout period, which can be set by an external capacitor to provide a flexible and precise reset pulse width tailored to specific system requirements.
- Watchdog Timer: The built-in watchdog timer ensures that the microprocessor does not hang in an indefinite loop. If the µP does not toggle the watchdog input within a preset timeout period, the LTC1232 generates a reset pulse.
- Brownout Protection: The device is equipped with brownout protection to prevent erratic system behavior during low voltage conditions.
- Low Power Consumption: Designed with power efficiency in mind, the LTC1232CS8#TR has a low supply current, making it ideal for battery-powered applications.
Applications:
The LTC1232CS8#TR is versatile and can be used in a variety of applications, including:
- Microprocessor systems
- Computers and controllers
- Portable and battery-powered equipment
- Intelligent instruments
- Automotive systems
With its precise voltage monitoring and reset capabilities, the LTC1232CS8#TR is an essential component in any microprocessor-based system, providing the necessary protection and stability for reliable operation under various conditions. Its tape and reel packaging (indicated by the #TR suffix) makes it suitable for automated assembly processes, enhancing production efficiency.
