LTC694CN8 - Power Supply Supervisory Circuit by Linear Technology

The LTC694CN8 is a versatile and reliable power supply supervisory integrated circuit (IC) designed and manufactured by Linear Technology, a brand synonymous with precision and quality in the electronics industry. This IC is engineered to monitor power supplies in microprocessor systems, providing the necessary protection and management to ensure stable and efficient operation.

With its robust feature set, the LTC694CN8 is ideal for applications that require precise power supply monitoring. It is capable of supervising +5V power supplies and offers a precision voltage monitor with a 4.65V threshold, ensuring that your system operates within safe voltage levels. The IC also offers a reset function, which provides an active low reset output that is guaranteed to remain asserted for at least 200ms after the +5V supply has risen above the reset threshold. This reset feature is crucial for allowing enough time for the power supply and processor to stabilize before the system starts its operation.

Furthermore, the LTC694CN8 includes a watchdog timer that can be set by an external capacitor, providing an additional layer of protection. The watchdog timer ensures that the system remains responsive and can recover from a fault condition. If the microprocessor fails to provide a periodic signal to the LTC694CN8, the watchdog timer will trigger a system reset, helping to prevent system hang-ups and malfunctions.

Designed for versatility, the LTC694CN8 comes in an 8-pin DIP package, making it easy to incorporate into a variety of designs without taking up significant board space. It is also characterized for operation from 0°C to 70°C, ensuring reliable performance across a wide range of environmental conditions.

Overall, the LTC694CN8 from Linear Technology is a high-quality power supply supervisory circuit that offers critical monitoring and protection features. Its precise voltage monitoring, reset capability, and watchdog timer make it an essential component for any microprocessor system that demands reliable and consistent power supply management.
