Maxim Integrated's DS1819BR-10/T&R Product Overview

The DS1819BR-10/T&R is a versatile and reliable microprocessor supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of integrated circuits. This component is specifically engineered to monitor the power supply and system health of microprocessor (µP) systems, ensuring that the system operates reliably and within its specified voltage thresholds.

The DS1819BR-10/T&R operates with a nominal threshold voltage of 2.88V, which makes it suitable for low-voltage applications. It is designed to assert a reset signal to the connected microprocessor when the VCC supply voltage drops below the preset threshold, ensuring that the µP starts up in a known state. The reset signal remains asserted for a minimum of 140ms after VCC rises above the reset threshold voltage, providing the µP with adequate time to stabilize.

One of the key features of this component is its compact form factor, as it comes in an SOT-23 package, making it ideal for space-constrained applications. The DS1819BR-10/T&R is also available in tape and reel (T&R) packaging, which facilitates efficient handling and placement during the manufacturing process, especially for high-volume production.

Moreover, the DS1819BR-10/T&R offers an active-low push-pull reset output, which provides a direct interface with the reset pin of the µP, eliminating the need for external pull-up resistors. This design simplifies the circuit and reduces component count.

With its wide operating temperature range of -40°C to +85°C, the DS1819BR-10/T&R is suitable for a variety of industrial and commercial environments. Its low supply current of only 20µA (typical) makes it an energy-efficient choice for battery-operated devices.

In summary, the Maxim Integrated DS1819BR-10/T&R microprocessor supervisory circuit is an essential component for system designers seeking to enhance the reliability of their µP systems. With its precision voltage monitoring, compact packaging, and ease of integration, it represents a smart choice for a wide range of applications.
