Maxim Integrated MAX6324HUT44+T Microprocessor Reset Circuit

The MAX6324HUT44+T is a highly reliable microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in μP and digital systems. It provides a significant level of protection to ensure that the system operates correctly even in the event of power supply fluctuations or failures. This component is ideal for portable, battery-powered equipment where extended battery life is crucial.

Featuring a low supply current of only 1.2μA, the MAX6324HUT44+T is optimized for low-power applications. This makes it an excellent choice for energy-sensitive devices, ensuring that the power consumption is kept to a minimum to prolong battery life. The reset output is guaranteed to remain in the correct state for VCC down to 1V, providing reliable operation even during low voltage conditions.

The device offers a preset reset threshold voltage of 4.4V, which is suitable for systems that operate at 5V power supply levels. The reset signal is asserted when the VCC supply voltage falls below the threshold, and it remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. This ensures that the system has sufficient time to stabilize before normal operation resumes.

Engineered for versatility, the MAX6324HUT44+T comes in a tiny 6-pin SOT-23 package, making it an excellent choice for space-constrained applications. It is also characterized for operation over the extended temperature range of -40°C to +85°C, which allows it to be used in environments with varying temperatures without compromising performance.

With its built-in features and compact design, the MAX6324HUT44+T from Maxim Integrated is a robust and reliable solution for system monitoring and is an essential component for maintaining the integrity of microprocessor systems.

Key features include:

• Precision monitoring of 5V power supplies
• Low supply current of 1.2μA for power conservation
• Guaranteed reset valid to VCC = 1V
• Preset VCC reset threshold of 4.4V
• Minimum reset timeout period to ensure system stability
• Available in a small 6-pin SOT-23 package
• Extended operating temperature range of -40°C to +85°C

Whether you're designing portable devices, embedded systems, or any other application requiring a reliable reset circuit, the MAX6324HUT44+T is an excellent choice to enhance system reliability and performance.
