Maxim Integrated MAX6316LUK45BX+T Microprocessor Reset Circuits

The MAX6316LUK45BX+T is a highly reliable and compact microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a trusted name in the development of innovative analog and mixed-signal products. This device is specifically engineered to monitor power supplies in µP and digital systems, providing a robust safeguard against power failures or unexpected system behavior due to voltage fluctuations.

This particular model, the MAX6316LUK45BX+T, is tailored to maintain system integrity by asserting a reset signal whenever the VCC supply voltage falls below its preset threshold of 4.5V. The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, ensuring the system has sufficient time to stabilize before resuming operation. This feature is critical for applications requiring high reliability and consistent performance.

The device comes in a compact 5-pin SOT-23 package, making it ideal for space-constrained applications. It offers an active-low, push-pull reset output, which provides a direct interface with other logic components without the need for external components, such as pull-up resistors. This integration simplifies design and enhances system reliability.

Key features of the MAX6316LUK45BX+T include:

• Immunity to short VCC transients
• Low supply current of 20µA (typical), which is beneficial for battery-powered applications
• Guaranteed reset valid to VCC = 1V, ensuring proper system reset even during low power conditions
• Factory-trimmed reset threshold for high accuracy
• Temperature range from -40°C to +85°C, suitable for industrial environments

Applications that can benefit from the robust features of the MAX6316LUK45BX+T include portable devices, computers, controllers, intelligent instruments, and critical µP and µC power monitoring systems. The device's precision voltage monitoring and low power consumption make it an excellent choice for designers looking to enhance system reliability and extend battery life in their products.

With Maxim Integrated's reputation for quality and reliability, the MAX6316LUK45BX+T is an excellent choice for ensuring your system maintains its performance and stability under varying power conditions.
