Maxim Integrated MAX6390XS31D4+T Microprocessor Supervisory Circuit

The MAX6390XS31D4+T is a high-quality microprocessor supervisory circuit designed and manufactured by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This compact, high-precision device is engineered to monitor power supplies in microprocessor systems, providing a reliable safeguard against power failures or malfunctions.

With its fixed-sense threshold voltage of 3.1V, the MAX6390XS31D4+T is tailored for systems that operate on standardized 3.3V power rails. The device is capable of asserting a reset signal whenever the VCC supply voltage falls below the preset threshold, ensuring that the microprocessor resets cleanly during power-up, power-down, or brown-out conditions. The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, thus providing a stable system reset.

The MAX6390XS31D4+T comes in a compact, surface-mountable SC70 package, making it an excellent choice for space-constrained applications. It is available in tape and reel form, indicated by the '+T' suffix, which facilitates automated assembly processes, thereby reducing manufacturing costs and time.

Key features of the MAX6390XS31D4+T include:

• Low supply voltage range from 1.2V to 5.5V, catering to a broad range of applications.
• Low quiescent current, maximizing battery life in portable applications.
• Immunity to short VCC transients, ensuring reliable operation under noisy conditions.
• 150ms (min) reset timeout period, providing ample time for the system to stabilize.
• Active-low RESET output, which is guaranteed to be in the correct state for VCC down to 1.1V.

This supervisory circuit is an ideal solution for managing system integrity in microprocessors, microcontrollers, and other digital systems that require precise monitoring and control of the power supply voltage. Its robust design and high accuracy make the MAX6390XS31D4+T a trusted component for ensuring system reliability in a diverse array of applications, from consumer electronics to industrial control systems.

With Maxim Integrated's reputation for quality and performance, the MAX6390XS31D4+T supervisory circuit is a top-tier choice for designers looking to enhance system stability and safeguard against power-related issues.
