Maxim Integrated MAX6417UK+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6417UK+T is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and µP systems in digital devices, ensuring proper operation through power-up, operation, and power-down. This supervisory circuit is especially suitable for portable and space-constrained applications due to its ultra-small SOT23 package.

The MAX6417UK+T provides a precise voltage monitoring solution with a factory-set reset threshold voltage. It is designed to maintain system integrity by asserting a reset signal whenever the VCC supply voltage falls below a predetermined threshold, preventing the µP from operating under conditions that could lead to unpredictable behavior.

Key Features:

• Factory-Set Reset Thresholds: The reset thresholds are available in a range of factory-set options to accommodate different system requirements.
• Low Power Consumption: This device is optimized for low-power consumption, making it ideal for battery-powered equipment.
• Manual Reset Input: A manual reset input allows for a system reset to be triggered with an external switch or logic signal.
• Reset Output: The reset output is available in both push-pull and open-drain configurations, providing flexibility in interfacing with other system components.
• Guaranteed Reset Valid to VCC = 1V: Ensures reliable operation even during low voltage conditions.
• Immune to Short VCC Transients: Transient immunity helps prevent false resets due to brief dips in the power supply.
• Wide Operating Temperature Range: The device operates over a broad temperature range, making it suitable for industrial applications.

The MAX6417UK+T is designed to support a variety of digital systems, such as computers, controllers, and intelligent instruments, by providing a critical supervisory function that enhances system reliability and prevents data corruption. Its small size, combined with its robust feature set, makes it an excellent choice for designers looking to integrate a supervisory function with minimal space impact.

With its precision monitoring and versatile features, the MAX6417UK+T from Maxim Integrated is an essential component for any system that demands reliable operation and protection against the effects of unpredictable power supply conditions.
