Linear Technology LTC1728ES5-5#TR Microprocessor Supervisory Circuit

The LTC1728ES5-5#TR is a high-performance microprocessor supervisory circuit designed by Linear Technology to monitor power supplies in digital systems. It ensures that the microprocessor has a reset signal active whenever the power supply falls below a designated threshold. This precision monitoring capability is crucial for systems that require consistent and reliable operations, such as embedded systems, portable electronics, and industrial control systems.

With a fixed threshold voltage of 5V, the LTC1728ES5-5#TR provides a robust solution for systems that operate at this standard logic level. Its tight 1.5% threshold accuracy guarantees that the reset signal is generated accurately at the right voltage level, preventing any premature or delayed system resets that could lead to system malfunctions or data corruption.

One of the key features of this supervisory circuit is its low power consumption. The LTC1728ES5-5#TR operates with a quiescent current of only 10µA, making it an excellent choice for battery-powered and portable applications where power efficiency is paramount. Additionally, the device comes in a compact SOT-23 package, which is ideal for space-constrained applications.

The supervisory circuit also includes a manual reset input, allowing for a system reset to be triggered externally. This feature adds an extra layer of control for system maintenance or emergency interventions. When the monitored supply voltage falls below the reset threshold, the LTC1728ES5-5#TR asserts a reset signal for a minimum of 200ms after the supply voltage rises above the reset threshold, ensuring that the system has adequate time to stabilize before resuming operation.

For systems that require a reliable monitoring solution, the LTC1728ES5-5#TR provides a combination of precision, low power consumption, and a small footprint. This makes it an excellent choice for designers looking to enhance system reliability without compromising on performance or space.

Overall, the LTC1728ES5-5#TR from Linear Technology is a dependable and efficient supervisory circuit that offers peace of mind for engineers and technicians by safeguarding their digital systems from the perils of undervoltage conditions.
