The DS1815R-10+T&R is a robust, precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor the power supplies in µP and digital systems. It provides a cost-effective solution for systems that require a reliable function to reset a microprocessor automatically upon power-up and maintain it in reset until the power supply has stabilized. Additionally, if there is a malfunction during operation, the DS1815 ensures that the µP resets to a known state.

Key Features

• Precision Monitoring: This device offers precise monitoring of 3.3V, 5V, and adjustable voltage power supplies, ensuring that the system is protected from unpredictable power levels which could lead to data corruption or hardware damage.
• Low Power Consumption: The DS1815’s low power consumption makes it an ideal choice for power-sensitive applications, extending the battery life of portable devices.
• Programmable Reset Timeout: It comes with a programmable timeout feature that allows designers to set the reset signal's active duration, providing additional flexibility to meet various system requirements.
• Compact SOT-23 Package: The small SOT-23 package is perfect for space-constrained applications, allowing for integration into compact system designs without compromising performance.

Applications

The DS1815R-10+T&R is versatile and can be used in a wide range of applications. It is particularly well-suited for:

• Portable/Battery-Powered Equipment
• Embedded Systems
• Computers and Servers
• Industrial Controllers
• Networking Equipment

Product Details

With the DS1815R-10+T&R, Maxim Integrated offers a supervisory solution that is easy to implement and requires minimal external components. The device is available in tape and reel (T&R) format for automated assembly processes, enhancing production efficiency. The active-low reset output guarantees compatibility with most microprocessors, and the reset threshold of 10% ensures that the µP is held in reset through power-up and down sequences.
