Maxim Integrated DS1811R-15+T&R Product Overview

The DS1811R-15+T&R from Maxim Integrated is a robust processor supervisor, designed to ensure the reliable operation of microprocessors (μPs) and digital systems. This component is essential for maintaining system integrity by monitoring the power supply voltage and providing a reset signal to the μP during power-up, power-down, and brownout conditions. The DS1811R-15+T&R is a versatile device suitable for a wide range of applications, including embedded systems, computers, controllers, and intelligent instruments.

This supervisor IC is available in a compact SOT-23 package, making it ideal for space-constrained applications. It operates over a wide temperature range, ensuring performance across various environmental conditions. The DS1811R-15+T&R features an active-low reset output, with a factory-trimmed reset threshold voltage set at 1.5V, which is particularly useful for 1.8V to 3.3V systems. The reset signal is maintained for a minimum of 150ms after the supply voltage has risen above the reset threshold level, providing ample time for the system to stabilize before the μP begins operation.

One of the key benefits of the DS1811R-15+T&R is its ease of use, requiring no external components for operation. This simplifies design and reduces the bill of materials for the end product. In addition, the device is supplied on tape and reel (T&R), which facilitates efficient pick-and-place manufacturing processes, making it an excellent choice for high-volume production.

The DS1811R-15+T&R also features a low supply current, which minimizes power consumption and makes it suitable for battery-powered applications. Its high precision voltage monitoring ensures reliable reset activation and contributes to the overall stability and safety of the system it is protecting.

In summary, the Maxim Integrated DS1811R-15+T&R is a high-quality, reliable processor supervisor that provides crucial protection for digital systems. Its compact size, ease of integration, and efficient manufacturing compatibility make it an excellent choice for designers looking to enhance system reliability and longevity.
