MAX6721UTZWD3 Description

The MAX6721UTZWD3 is a dual-channel voltage supervisor IC designed for power management applications. Manufactured by Analog Devices Inc./Maxim Integrated, this device is housed in a compact SOT23-6 package, making it suitable for space-constrained designs. Despite its small form factor, the MAX6721UTZWD3 offers robust performance and reliability, ensuring efficient power management and system monitoring.

MAX6721UTZWD3 Features

• Dual-Channel Voltage Monitoring: The MAX6721UTZWD3 is designed to monitor two separate voltage levels simultaneously. This dual-channel capability allows for comprehensive monitoring of power supply rails, ensuring that both primary and secondary power sources are within specified thresholds.
• Programmable Voltage Thresholds: With voltage thresholds set at 1.665V and 2.313V, the MAX6721UTZWD3 provides precise monitoring of power supply voltages. These thresholds can be used to trigger system alerts or corrective actions when voltages fall outside of acceptable ranges.
• Open Drain or Open Collector Output: The device features an open drain or open collector output, which is highly versatile and can be easily interfaced with a variety of digital systems. This flexibility allows for seamless integration into different types of electronic circuits.
• Active Low Reset: The reset function is active low, meaning that a low signal on the reset pin will initiate a system reset. This feature is essential for ensuring system stability and reliability, especially during power-up or brown-out conditions.
• 140ms Minimum Reset Timeout: The MAX6721UTZWD3 has a minimum reset timeout of 140 milliseconds, providing ample time for the system to stabilize before allowing normal operation to resume. This ensures that transient voltage fluctuations do not cause unintended system behavior.
• Surface Mount Technology: The MAX6721UTZWD3 is designed for surface mount applications, making it ideal for automated assembly processes. This mounting type reduces the overall footprint of the device on the PCB, contributing to more compact and efficient designs.
• Moisture Sensitivity Level 3: With an MSL rating of 3 (168 hours), the MAX6721UTZWD3 is suitable for a wide range of environmental conditions. This rating ensures that the device can withstand exposure to moisture during manufacturing and storage processes without compromising its performance.
