The MAX6367LKA29-T is a compact, highly reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This device is engineered to maintain system integrity by monitoring the power supply voltage in digital systems. It is particularly useful in applications where maintaining data integrity is critical, such as portable devices, computers, controllers, and intelligent instruments.

With a preset threshold voltage of 2.93V, the MAX6367LKA29-T ensures that the µP and other critical circuit components operate within safe voltage levels. In the event of a power failure or brownout condition, this supervisory circuit generates a reset signal to the µP, holding it in reset for a minimum of 140ms after the power supply has returned to a stable and acceptable level. This reset delay allows the power supply and system to stabilize before the µP resumes operation, preventing any erratic behavior or corruption of data.

The device is offered in a compact SOT-23 package, which is ideal for space-constrained applications. Its low supply current of 1.2µA (typical) makes it an excellent choice for battery-powered devices where power efficiency is paramount. The MAX6367LKA29-T operates over a wide temperature range from -40°C to +125°C, ensuring reliable performance in harsh environments.

Key features of the MAX6367LKA29-T include:

• Precision monitoring of 2.93V power-supply voltages
• Low 1.2µA supply current
• 140ms (min) reset timeout period
• Wide operating temperature range: -40°C to +125°C
• Compact SOT-23 package

Overall, the Maxim Integrated MAX6367LKA29-T is a robust solution for system monitoring, offering high accuracy, low power consumption, and a small form factor, making it a versatile choice for a wide range of applications that require reliable voltage supervision to protect critical system operations.
