Maxim Integrated DS1812R-5+T&R Product Overview

The DS1812R-5+T&R from Maxim Integrated is a robust microprocessor (µP) supervisory circuit designed to monitor the power supplies in digital systems. It provides a precise, cost-effective system for managing power supply and battery control functions in microprocessor systems. This component ensures that the microprocessor is reset to a known state during power-up, power-down, and brownout conditions.

Key Features

• Precision Monitoring: The DS1812R-5+T&R is engineered to precisely monitor 5V power supplies and other voltages.
• Automatic Reset: It generates a reset signal for a minimum of 150ms whenever the supply voltage drops below the factory-set reset threshold. This reset signal ensures that the connected microprocessor starts operating under the correct conditions every time.
• Low Power Consumption: This device is optimized for low power consumption, making it suitable for power-sensitive applications.
• Temperature Range: It operates efficiently over a wide temperature range, making it versatile for various industrial applications.
• Easy Integration: The DS1812R-5+T&R comes in a compact SOT-23 package, allowing for easy integration into system designs with space constraints.
• Active-High Reset Output: The active-high reset output provides a direct interface with other components that require an active-high signal for reset purposes.

Applications

The DS1812R-5+T&R is ideal for applications that require reliable monitoring of the power supply to ensure safe and predictable µP behavior. It is commonly used in:

• Computers and Servers
