Maxim Integrated MAX6863UK29+ Microprocessor Supervisory Circuit

The MAX6863UK29+ from Maxim Integrated is a highly reliable microprocessor (μP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This compact, low-power component is essential for monitoring the power supply and system health in microprocessor-based systems.

Key Features

• Voltage Monitoring: The MAX6863UK29+ monitors the supply voltage and ensures that it remains within acceptable thresholds, providing a reset output during out-of-tolerance conditions. It is preset to a threshold voltage of 2.93V, which is suitable for 3.3V-powered systems.
• Manual Reset: An external input is available to manually trigger a system reset, allowing for greater system control and diagnostics.
• Low Power Consumption: With its low supply current of only 1.6μA, the device is ideal for power-sensitive applications, helping to extend battery life in portable devices.
• High Accuracy: The reset threshold accuracy is ±1.5%, ensuring reliable monitoring and reset activation.
• Reset Timeout: After the supply voltage returns to an acceptable level, the reset signal is kept active for a minimum timeout period of 140ms, ensuring the system has sufficient time to stabilize.
• Compact Package: The device is offered in a space-saving SOT-23 package, which is highly beneficial for applications with limited board space.
