Linear Technology LTC692CS8 Supervisory Circuit
The LTC692CS8 is a state-of-the-art supervisory circuit designed by Linear Technology, now part of Analog Devices, to ensure the reliable operation of microprocessors (µPs) and digital systems. This compact and efficient device is housed in an 8-lead SOIC package, making it a space-saving solution for a wide range of applications including computers, controllers, and intelligent instruments.
Key Features
- Precision Monitoring: The LTC692CS8 offers precision monitoring of power supplies, ensuring that the system voltage levels remain within acceptable thresholds. This is critical for the proper functioning of sensitive electronic components.
- Power Fail Warning: The device provides an early warning signal for impending power failure, allowing systems to initiate backup protocols, such as saving data to non-volatile memory, before the power supply falls below safe operating levels.
- Reset Output: It generates a reset output signal during power-up, power-down, and brownout conditions. This output ensures that the µP and other devices start in a known state, which is essential for system stability and reliability.
- Low Power Consumption: Designed with power efficiency in mind, the LTC692CS8 has a low supply current, which helps to minimize the overall power consumption of the system it is integrated into.
- Adjustable Reset Threshold: The reset threshold voltage can be adjusted using external resistors, providing flexibility to work with different system voltages and requirements.
- Backup Battery Switchover: In the event of a primary power failure, the LTC692CS8 includes a backup battery switchover feature that ensures uninterrupted power supply to memory and real-time clocks.
