Maxim Integrated MAX6384XS23D3+T Microprocessor Reset Circuit

The MAX6384XS23D3+T from Maxim Integrated is a highly reliable and robust microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides a significant level of system integrity by ensuring that the μP boots up in a predictable state every time. This component is essential for systems that require a high degree of operational reliability and precision.

The device operates by asserting a reset signal whenever the VCC supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The reset output remains valid with VCC as low as 1V, which is particularly useful in low voltage applications. This feature ensures that the system has sufficient time to stabilize before the processor starts operating, thus preventing any erroneous operation due to insufficient power.

One of the key features of the MAX6384XS23D3+T is its factory-set reset threshold voltage, tailored for a 2.3V system, which eliminates the need for external components and adjustments. The device is available in a compact, 4-pin SC70 package, making it ideal for space-constrained applications. It also supports a wide temperature range of -40°C to +125°C, ensuring reliable operation in various environments.

Designed with a low supply current of typically 1.2μA, the MAX6384XS23D3+T is an energy-efficient solution for portable and battery-powered applications. The device's push-pull reset output provides a strong, active-low reset signal, which is compatible with most microprocessors and digital logic.

Furthermore, the MAX6384XS23D3+T comes in a tape and reel format denoted by the "+T" suffix, facilitating easy integration into automated manufacturing processes. This makes it an excellent choice for mass production and high-volume applications.

In conclusion, the Maxim Integrated MAX6384XS23D3+T is an indispensable component for system designers who require a simple, reliable, and efficient solution for monitoring power supply conditions and ensuring the proper operation of microprocessor-based systems.
