Maxim Integrated MAX824TEUK Microprocessor Supervisory Circuit

The Maxim Integrated MAX824TEUK is a compact, highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brownout conditions. The MAX824TEUK features a combination of functions including a reset output during power-up, power-down, and brownout conditions, as well as a manual reset capability.

The device comes in a space-saving 5-pin SOT-23 package, making it ideal for portable and space-constrained applications. It operates over a wide voltage range, making it suitable for a variety of systems with different supply voltage levels. The MAX824TEUK is capable of monitoring supply voltages of 2.63V, 2.93V, 3.08V, or 3.30V, which are common in digital systems.

With its low supply current of only 3µA (typical), the MAX824TEUK is optimized for low-power operations, ensuring minimal impact on the overall power consumption of the system it monitors. This feature is particularly important for battery-powered devices where power efficiency is crucial.

Key features of the MAX824TEUK include:

• Precision monitoring of 2.63V, 2.93V, 3.08V, or 3.30V supply voltages
• Low power consumption with 3µA supply current
• Reset output during power-up, power-down, and brownout conditions
• Manual reset capability
• Compact 5-pin SOT-23 package
• Operating temperature range from -40°C to +85°C

The MAX824TEUK is a versatile solution for system designers looking to enhance the reliability of their microprocessor-based systems without the need for additional components. Its ease of integration and robust feature set make it an excellent choice for a wide range of applications, including portable devices, embedded systems, and other digital electronic systems.
