Maxim Integrated MAX6377UR23 Voltage Detector

The MAX6377UR23 by Maxim Integrated is a precision voltage detector designed for monitoring power supplies in digital systems. It provides a significant layer of protection by ensuring that the system operates within safe voltage levels. This particular model is a part of Maxim's extensive line of microprocessor supervisory circuits, and it is tailored to deliver high accuracy and reliability.

At the heart of the MAX6377UR23 is its ability to monitor a +2.3V power-supply voltage with a precision threshold. When the monitored voltage falls below the factory-set threshold, the device generates a reset signal. This reset signal is maintained for a minimum of 140ms after the supply voltage rises above the reset threshold, ensuring that the system has adequate time to stabilize before normal operation resumes.

The device is available in a compact SOT23 package, making it suitable for space-constrained applications. Its low power consumption makes it an excellent choice for portable and battery-operated equipment. The MAX6377UR23 also features an active-low, open-drain reset output, which allows it to interface seamlessly with other logic components.

Key features of the MAX6377UR23 include:

• Factory-set reset threshold for +2.3V power supplies
• Immune to short voltage transients (glitch immunity)
• Low supply current of 1.2µA (typical), ideal for battery-powered applications
• 140ms (min) reset timeout period
• Compact SOT23-3 package
• Wide operating temperature range of -40°C to +125°C

Applications for the MAX6377UR23 span a wide range of electronic systems, including:

• Portable/battery-powered devices
• Microprocessor/microcontroller systems
• Computers and servers
• Embedded systems
• Industrial equipment

With its precise voltage monitoring and low power consumption, the MAX6377UR23 is an essential component for systems that require reliable operation under varying power conditions. Maxim Integrated's commitment to quality ensures that this voltage detector will provide a robust solution for safeguarding sensitive electronic systems.
