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.
