Maxim Integrated DS1814AR-5+T&R Product Overview

The DS1814AR-5+T&R from Maxim Integrated is a highly reliable and versatile microprocessor supervisory circuit, designed to monitor the power supply and temperature of embedded systems. This compact component ensures that digital systems operate optimally by providing essential protective functions that safeguard against system failures due to out-of-specification power supply voltages or excessive temperatures.

Key Features

• Supply Voltage Monitoring: The DS1814AR-5+T&R constantly checks the supply voltage levels and ensures that the microprocessor is reset to a known state during power-up, power-down, and brownout conditions. This feature is critical for preventing code execution errors due to insufficient power supply during system startup or shutdown.
• Programmable Watchdog Timer: This component comes with a programmable watchdog timer that can be set to a specific time interval. If the microprocessor does not provide a watchdog strobe within the set interval, the device will automatically reset, preventing system hang-ups and ensuring reliable operation.
• High Temperature Warning: The DS1814AR-5+T&R includes a temperature warning feature that alerts the system in case of high temperature conditions, allowing for preemptive measures to cool down the system or shut it down to prevent thermal damage.
• Active-High Reset: It provides an active-high reset output, which is particularly useful for interfacing with microprocessors that require a high signal to initiate a reset.
• Compact SOT-23 Package: The device comes in a small SOT-23 package, making it an ideal choice for space-constrained applications where board real estate is at a premium.
• Tape and Reel Packaging: Supplied in tape and reel packaging (denoted by T&R), this product is suitable for automated pick-and-place manufacturing processes, enhancing production efficiency and reducing manual handling.

Applications

The DS1814AR-5+T&R is an indispensable component for a wide array of applications, including:

• Embedded Systems
• Computers and Servers
