Maxim Integrated MAX6414UK22+T Microprocessor Reset Circuit

The MAX6414UK22+T is a highly reliable and compact microprocessor (μP) supervisory circuit designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering. This device is specifically engineered to monitor power supplies in μP and digital systems, providing a robust solution for system reset during power-up, power-down, and brownout conditions.

Encased in a small SOT-23 package, the MAX6414UK22+T is ideal for space-constrained applications where size is at a premium. It offers a precise factory-set reset threshold voltage of 2.2V, ensuring that your system operates within its intended voltage range. The reset output remains active for a minimum reset timeout period of 140ms after V_CC has risen above the reset threshold level, providing a reliable reset signal to the μP.

One of the key features of this device is its low supply current of only 1.5μA (typical), which makes it an energy-efficient choice for portable and battery-powered equipment. The MAX6414UK22+T also supports a wide operating voltage range from 1.2V to 5.5V, making it versatile for various applications.

The device ensures system stability by asserting a reset signal whenever the V_CC supply voltage falls below the preset threshold, preventing erroneous operation during power fluctuations. Additionally, the MAX6414UK22+T is equipped with a debounced manual reset input, allowing for a manual reset capability that can be triggered with an external push-button or logic signal.

This reset circuit is designed for use in a variety of applications, including computers, controllers, intelligent instruments, portable/battery-powered equipment, and embedded systems. Its robust feature set and compact form factor make the MAX6414UK22+T an excellent choice for ensuring the reliable operation of critical μP-based systems.

With Maxim Integrated's commitment to high-quality and durable products, the MAX6414UK22+T represents a dependable and efficient solution for system designers looking to enhance the operational stability of their electronic systems.
