Maxim Integrated MAX6436UT+T Microprocessor Supervisory Circuits

The MAX6436UT+T from Maxim Integrated is a sophisticated microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant layer of protection by ensuring that the system's voltage levels remain within operational thresholds, thus safeguarding the system from erratic behavior that can arise from power surges, dips, or failure.

This device is particularly adept at managing system resets, offering an active-low reset output which remains asserted for a minimum of 140ms after Vcc has risen above the reset threshold level. This feature ensures that the µP has ample time to initialize and stabilize before commencing operations. The reset threshold voltage for the MAX6436UT+T is factory-set and can be chosen from a range of standard voltages to match specific system requirements.

One of the key features of this supervisory circuit is its low power consumption, making it an ideal choice for portable and battery-operated devices. It operates over a wide voltage range of 1.8V to 5.0V, which allows for flexibility in various application designs. The MAX6436UT+T is also designed to handle transient conditions, which makes it robust in environments where power fluctuations are common.

The device is provided in a small 6-pin SOT23 package, which is both space-saving and convenient for high-density circuit boards. Its surface-mount form factor is suited for automated assembly processes, and the lead(Pb)-free composition is in compliance with current environmental standards for electronic components.

Applications for the MAX6436UT+T are diverse and include portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP and µC power monitoring. Its reliability and precision make it a critical component for ensuring the stable operation of sensitive electronic systems.

Maxim Integrated's commitment to quality and performance is reflected in the MAX6436UT+T, making it a trusted choice for designers who require a reliable supervisory solution for their digital systems.
