Product Overview: LTC692CS8#PBF
The LTC692CS8#PBF is a highly reliable supervisory circuit designed by Linear Technology, now part of Analog Devices, to monitor power supplies in microprocessor systems. It provides a precise, low-cost method to monitor power functions and increases the robustness of system operation by initiating a proper reset during power-up, power-down, and brownout conditions.
Key Features
- Voltage Monitoring: This product is designed to monitor the voltage levels of power supplies, ensuring that the microprocessor and other critical components operate within the specified voltage range. It helps to prevent data corruption and system failures caused by inadequate power supply levels.
- Reset Functionality: The LTC692CS8#PBF generates a reset output during power-up, power-down, and brownout conditions. The reset output remains operational with supply voltages as low as 1V, making it versatile for various applications.
- Low Power Consumption: With its low power consumption, this supervisory circuit is ideal for power-sensitive applications. It ensures minimal drain on the system's power resources, contributing to overall energy efficiency.
- High Accuracy: The device features a precision voltage reference and comparator circuit that monitors the VCC for undervoltage (UV) conditions. When the VCC falls below the factory-programmed reset threshold, the reset output is asserted.
- Compact Size: Housed in an 8-lead SOIC package, the LTC692CS8#PBF is compact and suitable for space-constrained applications without compromising on performance.
Applications
The LTC692CS8#PBF is widely used in microprocessor systems where accurate monitoring of the power supply voltage is crucial. It is particularly beneficial in systems where a reliable reset signal is needed to bring the microprocessor back to its initial state during power disturbances. Typical applications include:
- Portable/Battery-Powered Equipment
- Computers and Controllers
- Intelligent Instruments
- Automotive Systems
- Industrial Systems
Conclusion
The LTC692CS8#PBF supervisory circuit is a testament to Linear Technology's commitment to producing high-quality, reliable components that enhance system stability and performance. This product is a crucial element for any design engineer looking to safeguard their microprocessor-based systems against power supply irregularities.
