The DS1819BR-10+T from Maxim Integrated is a versatile and highly reliable microprocessor (μP) supervisory circuit that ensures the proper operation of μP systems. This compact component is designed to monitor the system voltage and provide a reset signal to the μP during power-up, power-down, and brown-out conditions. The DS1819BR-10+T operates over a wide voltage range and offers a precise monitoring solution that is essential for maintaining the integrity of digital systems.

With its factory-trimmed reset thresholds, the DS1819BR-10+T is capable of detecting out-of-tolerance power supply conditions and asserting a reset signal to the μP, thus preventing code execution errors. It features an active-low reset output, which remains asserted until the system voltage has stabilized and the internal timer has expired, ensuring the μP has adequate time to initialize after a power disturbance.

The DS1819BR-10+T variant has a nominal reset threshold of 4.63V, tailored for systems that operate at 5V power supply levels. It comes in a compact SOT-23 package, making it ideal for space-constrained applications. The device's temperature range of -40°C to +85°C allows for operation in a wide range of environmental conditions.

Key features of the DS1819BR-10+T include:

• Precision monitoring of 5V power supplies
• 140ms min power-on reset delay
• Active-low reset output
• Low supply current of 20μA (typical)
• Compact SOT-23 package
• Temperature range from -40°C to +85°C

The DS1819BR-10+T is ideal for use in microprocessor systems, computers, controllers, and intelligent instruments where reliable system operation is critical. Its ease of integration and minimal external components make it a go-to solution for system designers looking to enhance the resilience and robustness of their electronic products.
