Maxim Integrated MAX6314US46D2+T Microprocessor Reset Circuit

The MAX6314US46D2+T is a high-quality microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset function, ensuring that the µP boots up in a known state every time.

This compact and efficient component is ideal for portable devices due to its low power consumption. The MAX6314US46D2+T is designed to assert a reset signal whenever the VCC supply voltage declines below a preset threshold, maintaining it until the supply voltage recovers sufficiently. The reset output remains operational with VCC as low as 1V, which is particularly useful in low-voltage applications.

One of the key features of the MAX6314US46D2+T is its precision factory-set reset thresholds, suitable for 4.6V supply voltages. This ensures that the device can cater to specific requirements without the need for external adjustments. The product also boasts an impressive reset timeout period of 140ms (min), providing ample time for the system to stabilize before coming out of reset.

The device comes in a compact SOT-143 package, making it an excellent choice for space-constrained applications. It is also characterized for operation over a wide temperature range, from -40°C to +85°C, which allows its use in various environmental conditions.

With its built-in watchdog timer and manual reset capability, the MAX6314US46D2+T provides additional layers of system protection. The manual reset input allows for a reset to be triggered with an external pushbutton or logic signal, offering a convenient way to restart the system without power cycling.

Maxim Integrated’s commitment to quality is evident in the MAX6314US46D2+T, with its robust design ensuring that it meets the stringent requirements of a wide array of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring.

In summary, the MAX6314US46D2+T from Maxim Integrated is a reliable and efficient solution for system reset management in µP-based systems, providing stability, precision, and ease of integration in a miniature package.
