Maxim Integrated DS1819AR-10+T&R Product Overview

The DS1819AR-10+T&R is a versatile and reliable microprocessor supervisory circuit designed and manufactured by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products and technologies. This compact and efficient component is engineered to monitor power supplies in microprocessor and digital systems, providing a crucial safeguard against power failures and ensuring the stability and integrity of system operations.

The DS1819AR-10+T&R offers an array of features that make it an essential part of any microprocessor-based system. With its precise monitoring capabilities, it can detect out-of-tolerance power supply conditions and provide a reset signal to the host processor, effectively rebooting the system back to a known, safe state. This reset signal remains active until the power supply returns to an acceptable level, and for a preset period after, ensuring proper system recovery.

One of the key specifications of the DS1819AR-10+T&R is its reset threshold voltage of 4.63V at +25°C, which is ideal for 5V power supplies. Its active-low, open-drain reset output guarantees compatibility with a wide range of microprocessors and other digital systems. The device also features a low supply current, making it an energy-efficient choice for battery-operated applications.

The DS1819AR-10+T&R comes in a small, 4-pin SOT-143 package, which allows for easy integration into system designs without taking up significant board space. Its temperature range of -40°C to +85°C ensures reliable operation across various environmental conditions, making it suitable for industrial and automotive applications, as well as consumer electronics.

Available in tape and reel packaging (denoted by the T&R suffix), the DS1819AR-10+T&R is optimized for automated assembly processes, streamlining manufacturing and reducing production costs. This makes it an ideal choice for high-volume production runs where consistency and efficiency are paramount.

In summary, the Maxim Integrated DS1819AR-10+T&R is a high-performance supervisory circuit that offers robust protection for microprocessor systems, ensuring they operate reliably in the face of power supply uncertainties. Its compact form factor, low power consumption, and wide operating temperature range make it a versatile solution for a multitude of applications.
