Maxim Integrated MAX6856UK31D3+T Microcontroller Supervisory Circuit

The MAX6856UK31D3+T from Maxim Integrated is a highly reliable microcontroller supervisory circuit, designed to monitor power supplies in microprocessor and digital systems. It provides a precise, low-power voltage monitor with a built-in microprocessor reset generator. This component is specifically engineered to maintain system integrity through various power fluctuations and to ensure a safe start-up and operation of your electronic device.

With its compact SOT-23 package, the MAX6856UK31D3+T is an ideal solution for space-constrained applications. It offers a fixed-sense threshold voltage of 3.1V, which makes it suitable for monitoring 3.3V power supplies. The device features a manual reset input, allowing the system processor to initiate a reset manually. This feature is critical for systems that require user-initiated resets or for those that need to implement a reset sequence during software updates or maintenance.

The supervisory circuit also includes a 200ms (min) reset timeout period, ensuring that the system has adequate time to stabilize before the microcontroller starts its operation. This timeout period is crucial for preventing system errors and ensuring a reliable boot-up process. The MAX6856UK31D3+T operates over a wide temperature range of -40°C to +125°C, catering to industrial applications that may be exposed to extreme conditions.

Key features of the MAX6856UK31D3+T include:

• Fixed Reset Threshold Voltage: 3.1V suitable for monitoring 3.3V power supplies.
• Manual Reset Input: Provides the ability to trigger a system reset manually.
• Low Power Consumption: Ideal for battery-powered and portable devices.
• 200ms Minimum Reset Timeout: Guarantees a proper system reset and stabilizes the power-up sequence.
• Wide Operating Temperature Range: Reliable performance in a range of environmental conditions.
• Compact SOT-23 Packaging: Space-saving design for high-density board layouts.

This supervisory circuit is a testament to Maxim Integrated's commitment to providing advanced circuit protection solutions.
