Product Overview: DS1813R-5/T&R from Maxim Integrated

The DS1813R-5/T&R is a sophisticated microprocessor supervisory circuit designed by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This component is engineered to enhance the reliability of microprocessor systems by monitoring the power supply and asserting a reset signal to the microprocessor during power-up, power-down, and brown-out conditions. The DS1813R-5/T&R ensures that the microprocessor and associated circuitry initialize in a known state, which is crucial for maintaining system integrity.

The DS1813R-5/T&R comes in a compact SOT-23 package, making it an ideal choice for space-constrained applications. It features an active-low reset output, which remains asserted for a minimum of 250ms after the supply voltage exceeds the reset threshold level. This timing ensures that the microprocessor has sufficient time to stabilize before the system start-up. The reset threshold level for this variant is precisely set at 4.63V, suitable for 5V-powered systems.

One of the key attributes of the DS1813R-5/T&R is its low supply current requirement, which makes it an energy-efficient solution for portable and battery-powered devices. Additionally, it is characterized for operation over a wide temperature range, which makes it versatile for use in various environmental conditions.

The device comes in tape and reel packaging, denoted by the T&R suffix, which facilitates efficient handling and placement during the automated manufacturing process. This packaging is highly beneficial for high-volume production, ensuring a streamlined assembly process and reducing manual handling.

In summary, the DS1813R-5/T&R is a reliable and essential component for systems requiring robust power supply monitoring. Its precise threshold level, low power consumption, and compact form factor make it a top choice for designers looking to enhance the operational stability of their microprocessor-based systems. With its easy integration and proven performance, the DS1813R-5/T&R is a testament to Maxim Integrated's commitment to delivering high-quality and dependable products.
