Maxim Integrated DS1814CR-5-U+ Product Overview

The DS1814CR-5-U+ is a state-of-the-art microprocessor supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This compact, highly reliable component is engineered to monitor power supplies in microprocessor and digital systems, providing a crucial safety net against power failures and ensuring the proper operation of the system.

This supervisory circuit is particularly adept at managing 3.3V power supplies, with a precise factory-trimmed power-fail input voltage (V_PF) that ensures accurate monitoring. The DS1814CR-5-U+ is also versatile, featuring an active-low, push-pull reset output which remains asserted until the V_CC voltage exceeds the reset threshold, and then maintains the reset for approximately 150ms after V_CC has risen above the reset threshold. This ensures that the microprocessor has adequate time to initialize and stabilize before commencing operation.

One of the key features of the DS1814CR-5-U+ is its watchdog timer, which helps prevent system failures due to software lockup. This timer requires a periodic signal from the microprocessor within a preset time window to avoid triggering a system reset. This feature is critical for applications where continuous system operation is paramount, and it contributes to the overall reliability and stability of the system it monitors.

With its compact SOT-223 package, the DS1814CR-5-U+ is designed for space-constrained applications. It is ideal for use in a wide range of products, from portable devices to complex digital systems, where maintaining the integrity of the power supply and system operation is essential. Its low power consumption also makes it suitable for battery-operated devices.

Maxim Integrated's commitment to quality ensures that the DS1814CR-5-U+ meets the highest standards of performance and reliability. This supervisory circuit is an essential component for designers looking to enhance system integrity and protect against the consequences of unpredictable power supply conditions.

Overall, the DS1814CR-5-U+ from Maxim Integrated represents a robust solution for microprocessor system monitoring, offering a blend of precision, reliability, and convenience that designers and engineers can trust to safeguard their digital systems.
