Maxim Integrated DS1812R-10/T&R Product Overview

The DS1812R-10/T&R from Maxim Integrated is a highly reliable, precision microprocessor supervisory circuit that is essential for monitoring the power supply and temperature of microprocessor (µP) systems. This component ensures that the µP and its associated circuitry are reset to a known state during power-up, power-down, or brown-out conditions. The DS1812R-10/T&R is an indispensable tool for maintaining system integrity and preventing data corruption in a wide range of applications.

This supervisory circuit is available in a compact SOT-23 package, making it suitable for use in space-constrained applications. It is designed to monitor the power supply voltage levels and assert a reset signal to the µP whenever the supply voltage drops below a predetermined threshold. The reset signal remains asserted for a minimum of 150ms after the supply voltage exceeds the reset threshold level, ensuring proper system reset.

The DS1812R-10/T&R operates over a wide voltage range and features low power consumption, which is critical for battery-operated devices. With its precision factory-trimmed threshold levels, it provides a reliable reset output without external components, simplifying the design and reducing the bill of materials.

One of the key features of the DS1812R-10/T&R is its ability to operate at a reset threshold level of 4.65V (nominal), which is suitable for 5V-powered systems. This device is supplied in tape and reel form (T&R), facilitating efficient assembly during the manufacturing process, especially for high-volume production.

Maxim Integrated's commitment to quality means that the DS1812R-10/T&R is built to meet stringent industry standards. It is designed for use in various applications, including embedded systems, computers, controllers, and intelligent instruments where precise power supply monitoring is critical.

In summary, the DS1812R-10/T&R is a robust, compact, and precise supervisory circuit that provides essential protection for microprocessor systems. Its ease of integration, combined with Maxim Integrated's reputation for quality, makes it a top choice for designers looking to enhance system reliability and performance.
