Maxim Integrated MAX6444US16K/V+T Microprocessor Supervisory Circuit

The MAX6444US16K/V+T is a high-quality microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 1.6V supply voltage.

This supervisory circuit is particularly adept at maintaining system integrity through monitoring. It asserts a reset signal whenever the VCC supply voltage falls below its preset threshold, ensuring that the µP resets cleanly during power-up, power-down, and brownout conditions. The reset output remains operational with VCC as low as 1.2V, and the reset timeout period is externally adjustable with a capacitor, offering design flexibility.

The MAX6444US16K/V+T comes in a compact SOT-143 package, making it suitable for space-constrained applications. It is also available in a variety of standard threshold voltages, allowing designers to select the appropriate version for their specific requirements. The device's low supply current of 6µA (typ) is particularly beneficial for battery-powered equipment, contributing to extended battery life.

Key features of the MAX6444US16K/V+T include a manual reset input, which provides a direct way to initiate a system reset. There is also a debounced manual reset input, which ensures that the system reset is free from glitches and false triggers. The device is designed to be robust, with the ability to handle transient conditions and maintain stable operation.

The MAX6444US16K/V+T supervisory circuit is ideal for portable devices, computers, controllers, and intelligent instruments where reliable monitoring of the power supply voltage is critical. It is offered in tape and reel packaging, denoted by the "+T" suffix, which facilitates automated assembly processes for high-volume production.

In summary, Maxim Integrated's MAX6444US16K/V+T is a versatile, low-power, and reliable solution for µP system monitoring, ensuring that your digital systems operate smoothly and efficiently.
