Product Overview: MAX6367LKA44-T from Maxim Integrated

The MAX6367LKA44-T is a highly reliable, low-power 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 and watchdog functions, ensuring that the µP resets into a known state during power-up, power-down, or brownout conditions.

Key Features

• Voltage Monitor: The device keeps a vigilant eye on the system voltage, asserting a reset signal whenever the VCC supply voltage falls below the preset threshold, ensuring the µP initializes correctly during power-up.
• Programmable Watchdog Timer: A vital feature for systems that require regular monitoring, the watchdog timer can be programmed to the specific needs of the application, guarding against system failures due to software lock-up.
• Manual Reset Input: This feature allows for an external signal to trigger a system reset, offering an additional layer of control for system management.
• Low Power Consumption: With its focus on energy efficiency, the MAX6367LKA44-T is ideal for portable and battery-operated applications, minimizing power drain and extending operational life.
