LTC1728ES5-2.5/TR Microprocessor Supervisory Circuit

The LTC1728ES5-2.5/TR is a precision microprocessor supervisory circuit designed by Linear Technology to maintain system integrity in digital and mixed-signal systems. This compact device comes in a low-profile SOT-23 package, making it an ideal choice for space-constrained applications where reliable voltage monitoring is essential.

The LTC1728ES5-2.5/TR operates over a temperature range of -40°C to +125°C, ensuring consistent performance across a wide range of environmental conditions. This feature is particularly important for systems that are exposed to varying temperatures or are required to operate in harsh environments.

Key Features:

• Precision Monitoring: The device offers a precise threshold voltage of 2.5V, making it suitable for monitoring 2.5V power supplies. This precision ensures that the system operates within its safe voltage limits, thus protecting the integrity of the microprocessor and other sensitive components.
• Low Power Consumption: With a very low quiescent current of 10µA, the LTC1728ES5-2.5/TR is an energy-efficient solution that contributes to the overall power management of the system, making it ideal for battery-powered and portable applications.
• Reset Output: The device provides a reset output that remains asserted for 200ms after the voltage returns to an acceptable level, ensuring the system has sufficient time to stabilize before resuming operation.
• High Accuracy: The LTC1728ES5-2.5/TR boasts an accuracy of ±1.5% over the full temperature range, providing reliable monitoring that can be trusted in critical applications.
• Manual Reset Input: An additional feature of this supervisory circuit is the manual reset input, which allows for an external trigger to initiate a system reset, offering an extra layer of control for system maintenance or troubleshooting.

This product is available in a tape and reel format denoted by the "/TR" suffix, facilitating automated pick-and-place manufacturing processes. The LTC1728ES5-2.5/TR is a testament to Linear Technology's commitment to high-quality, reliable components, ensuring systems stay operational and protected against the consequences of undervoltage conditions.

Whether used in portable devices, embedded systems, or critical monitoring applications, the LTC1728ES5-2.5/TR provides peace of mind with its robust feature set and Linear Technology's renowned precision engineering.
