Maxim Integrated MAX6801UR40D2+T Voltage Detector

The MAX6801UR40D2+T is a compact, highly reliable voltage detector from Maxim Integrated, designed to monitor supply voltages and provide a reset signal to microcontrollers (MCUs) and digital systems. This ensures that in the event of power supply fluctuations, the system can reset and restart operations once the voltage returns to acceptable levels, thereby safeguarding the system against data corruption and erratic behavior.

With a precision preset V<sub>CC reset threshold of 4.0V, the MAX6801UR40D2+T is optimized for systems that operate within this voltage range and require a stringent monitoring mechanism. The device features an active-low reset output, which means that the reset signal is asserted (goes low) when the monitored voltage drops below the threshold, and remains asserted for a period after the voltage rises above the threshold to ensure system stability.

The reset timeout period for this voltage detector is factory-set to 200ms, providing a sufficient delay to allow the power supply to stabilize before the system attempts to resume normal operations. This timeout is critical in preventing the system from restarting prematurely, which can lead to a series of resets that could damage the system or lead to data loss.

The MAX6801UR40D2+T comes in a compact SOT-23 package, which is ideal for space-constrained applications. Its small size does not compromise its performance, as it offers low supply current characteristics, making it suitable for battery-operated devices where power efficiency is crucial.

Key features of the MAX6801UR40D2+T include:

• Precision monitoring of 4.0V power supply voltages
• Active-low reset output with a 200ms timeout
• Low supply current, enhancing battery life for portable devices
• Compact SOT-23 package suitable for space-limited applications
• High reliability and robustness for industrial and consumer electronics

Overall, the MAX6801UR40D2+T from Maxim Integrated is a critical component for systems that require consistent monitoring and control of their power supply to ensure reliable and predictable operation.
