Maxim Integrated DS1831AS+T&R Product Overview

The DS1831AS+T&R from Maxim Integrated is a robust, high-precision microprocessor supervisory circuit designed to monitor power supplies in digital systems and provide a secure environment for the processor. This component ensures that the system's microprocessor always starts up in a known state, which is crucial for maintaining system integrity and reliability.

This supervisory circuit is a vital component for applications that demand high reliability and precision, such as embedded systems, servers, and industrial control systems. The DS1831AS+T&R is engineered to monitor the system voltage and automatically execute a processor reset if it detects that the voltage has dropped below a predefined threshold. This automatic reset ensures that the system does not operate under conditions that could lead to unpredictable behavior or data corruption.

The DS1831AS+T&R comes in a compact SOT-23-5 package, making it an excellent choice for space-constrained applications. It is also characterized by its low power consumption, which helps to reduce the overall energy footprint of the systems in which it is used. The device is supplied on tape and reel (T&R), which facilitates efficient handling and placement during the manufacturing process, particularly for high-volume production environments.

Key features of the DS1831AS+T&R include:

• Programmable reset threshold voltage, allowing customization for specific system requirements.
• Low power consumption, enhancing system power efficiency.
• Active-low reset output, which ensures compatibility with a wide range of microprocessors.
• Reset pulse width of 350ms (min), ensuring a reliable processor reset.
• Immunity to short VCC transients, avoiding false triggering of the reset function.
• Wide operating temperature range, suitable for industrial and commercial applications.

The DS1831AS+T&R is a testament to Maxim Integrated's commitment to providing high-quality, reliable integrated circuits that cater to the needs of advanced digital systems. With its precision voltage monitoring and reset capabilities, this supervisory circuit is an essential component for maintaining the health and stability of your electronic applications.
