Maxim Integrated MAX6356SVUT Microprocessor Supervisory Circuit

The MAX6356SVUT from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 3.3V power supply.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6356SVUT features an active-low reset signal, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.

Key features of the MAX6356SVUT include:

• Reset Threshold Voltage: Precisely set for a 3.3V system, ensuring compatibility and optimal performance for standard power supply voltages.
• Low Power Consumption: With its low supply current of only 1.6µA, it is ideal for power-sensitive applications, extending the battery life of portable devices.
• Manual Reset Input: A debounced manual reset input allows for a manual system reset, providing additional system control and flexibility.
• Compact Package: The MAX6356SVUT comes in a small, 6-pin SOT-23 package, making it suitable for space-constrained applications.
• Watchdog Timer: A built-in watchdog timer ensures that the µP does not lock-up, which is critical for autonomous systems.

This supervisory circuit is suitable for a wide range of applications, including portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP and µC power monitoring. With its built-in features, the MAX6356SVUT provides an effective solution for system reliability and recovery without the need for complex programming or additional hardware.

As part of Maxim Integrated's commitment to quality, the MAX6356SVUT is rigorously tested and ensures long-term reliability for the end user. Whether in industrial, commercial, or consumer applications, this supervisory circuit stands out as a dependable component in any microprocessor-based system.
