LTC1728ES5-5#TRPBF - Microprocessor Supervisory Circuit

The LTC1728ES5-5#TRPBF is a high-performance microprocessor supervisory circuit designed by Linear Technology to monitor power supplies in digital systems. It ensures reliable operation and protection for microprocessors, microcontrollers, and other digital systems. This precision monitoring device is particularly suited for portable and space-constrained applications due to its small form factor.

With a fixed threshold voltage of 5V, the LTC1728ES5-5#TRPBF provides a precise monitoring system, ensuring that the supply voltage remains within the necessary operating limits. It offers a tight threshold accuracy of ±1.5% over the entire temperature range of -40°C to 85°C, which is essential for systems that require consistent performance and stability.

The device features a low power consumption with a typical supply current of only 10µA, which makes it an excellent choice for battery-powered equipment. This supervisory circuit comes in a compact SOT-23 package, allowing for easy integration into system designs without taking up significant board space.

One of the key features of the LTC1728ES5-5#TRPBF is its reset output, which remains asserted for a minimum of 200ms after the supply voltage has risen above the reset threshold. This reset timeout ensures that the system has sufficient time to stabilize before resuming operation, thus preventing any erroneous actions during power-up.

In addition to the reset function, the device includes a manual reset input that allows the user to trigger a system reset with an external pushbutton or logic signal. This feature enhances the flexibility and control for system maintenance and troubleshooting.

The LTC1728ES5-5#TRPBF is designed to be robust, with over-temperature protection and the ability to operate over a wide range of supply voltages, from 1.2V to 6V. This versatility ensures that it can be used in a variety of applications including computers, controllers, intelligent instruments, and portable electronics.

Overall, the LTC1728ES5-5#TRPBF from Linear Technology is a reliable and efficient solution for system voltage monitoring, providing the necessary features to maintain system integrity and prevent data corruption due to power anomalies.
