The DS1814CR-10-U is a versatile and robust microprocessor supervisory circuit, meticulously crafted by Maxim Integrated to ensure the reliable operation of microprocessor (µP) systems. This compact, highly-integrated device offers a multitude of features that are essential for monitoring and controlling system functionality, particularly in applications where precision and reliability are paramount.

Key Features

• Power Monitoring: The DS1814CR-10-U provides precise power supply monitoring, ensuring that the µP is always operating within safe voltage levels. It features a +4.65V threshold, which is ideal for 5V-powered systems.
• Reset Signal: It generates an active-low reset signal, which is crucial for initializing the µP into a known state upon startup or during a brownout condition. This signal remains asserted for a minimum of 150ms after the power supply has stabilized, guaranteeing a proper system reset.
• Watchdog Timer: A built-in watchdog timer serves as a fail-safe mechanism, forcing the system into a reset state if the µP fails to provide a periodic signal. This feature is crucial for systems that require high reliability and fault tolerance.
• Manual Reset: An additional manual reset input allows for an external trigger to initiate a system reset, providing designers with greater control and flexibility in managing system states.
• Compact Packaging: The device comes in a space-saving microSOP package, making it an excellent choice for space-constrained applications without compromising on functionality.

Applications

The DS1814CR-10-U is ideally suited for a wide range of applications, including but not limited to:

• Computers and Servers
• Embedded Systems
• Communication Equipment
• Portable/Battery-Powered Devices
• Industrial Controllers

With its robust feature set and Maxim Integrated's reputation for quality, the DS1814CR-10-U stands out as a reliable solution for system monitoring and control. Whether for new designs or upgrades to existing systems, this supervisory circuit is engineered to enhance system integrity and prevent costly downtime.
