Maxim Integrated DS1819AR-5-U+ Product Overview

The DS1819AR-5-U+ is a robust, versatile microprocessor monitoring IC designed by Maxim Integrated, a renowned leader in the development of integrated circuits. This compact device serves as an essential component for system reliability, providing real-time monitoring to ensure the proper functioning of microprocessors and digital systems.

Key Features

• Voltage Monitoring: The DS1819AR-5-U+ actively monitors the supply voltage (Vcc) levels of microprocessors, asserting a reset signal whenever Vcc drops below the factory-set threshold, typically 4.63V for the DS1819-5 version. This ensures the system resets reliably during power-up, power-down, and brown-out conditions.
• Reset Timeout: After Vcc rises above the reset threshold, the device maintains the reset signal for a period of approximately 150ms to 1200ms (min to max), providing ample time for the microprocessor and the system to stabilize.
• Temperature Range: It operates across a wide temperature range from -40°C to +85°C, making it suitable for industrial applications where environmental conditions can vary significantly.
• Low Power Consumption: Designed for efficiency, the DS1819 consumes minimal power, making it an ideal choice for battery-operated and portable devices where power conservation is critical.
• Compact Package: The device comes in a space-saving SOT-23-5 package, which is highly beneficial for designs where board space is at a premium.
