Maxim Integrated MAX6384XS17D3+T Microprocessor Reset Circuit

The MAX6384XS17D3+T is a highly reliable and robust microprocessor (µP) supervisory circuit, designed and manufactured by Maxim Integrated. This precision device is engineered to monitor power supplies in µP and digital systems, providing a significant layer of protection by ensuring that the system's voltage levels remain within operational thresholds. It is particularly suitable for portable devices, computers, controllers, and intelligent instruments where precise monitoring is critical.

With an ability to assert a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold level, the MAX6384XS17D3+T ensures that the µP boots up in a known state. The reset output remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold level, thus providing the system with a stable interval to recover after a power-down or brown-out condition.

This device features a reset threshold voltage of 1.7V, which caters to low-voltage applications, and it comes in a compact, surface-mountable SOT-343 package. The MAX6384XS17D3+T also offers an active-low, push-pull reset output, which provides a direct interface with µP reset or chip enable pins without the need for external components.

The MAX6384XS17D3+T is characterized for operation over a wide temperature range, from -40°C to +125°C, making it suitable for use in environments with extreme temperature variations. The device is also provided in a tape and reel format (denoted by the +T suffix), which facilitates efficient handling and placement during the manufacturing process, especially for high-volume production.

This supervisory circuit is part of Maxim Integrated's commitment to offering power management solutions that enhance the reliability and performance of electronic systems. Its low power consumption and small footprint make it an excellent choice for space-constrained applications that require minimal power overhead and high integration.

Overall, the MAX6384XS17D3+T is a testament to Maxim Integrated's expertise in designing power management ICs that meet the strict requirements of modern electronic systems, ensuring that they operate reliably and effectively under varying conditions and power supply uncertainties.
