MAX809S Description

The MAX809S is a high-performance voltage detector designed to monitor and ensure the stability of power supply voltages in various electronic systems. Manufactured by UMW, this supervisor is part of the MAX809 family and offers a reliable solution for maintaining system integrity through precise voltage monitoring. With a voltage threshold of 2.93V, the MAX809S is ideal for applications requiring a low-effective voltage detection mechanism. The device features a reset timeout of at least 150ms, ensuring that the system has sufficient time to stabilize before the reset signal is deactivated. The MAX809S is packaged in a surface-mount format, making it suitable for compact and high-density PCB designs. Additionally, it is available in a tape and reel package, facilitating easy handling and integration into automated assembly processes.

MAX809S Features

• Voltage Detection: The MAX809S is designed to monitor a single voltage level, providing accurate detection at a threshold of 2.93V. This precision ensures that the system remains stable and operational within the specified voltage range.
• Reset Functionality: The device features an active-low reset output, which asserts the reset signal when the monitored voltage falls below the threshold. This reset mechanism helps prevent system malfunctions and ensures a safe startup sequence.
• Reset Timeout: With a minimum reset timeout of 150ms, the MAX809S provides ample time for the system to stabilize after a power interruption or voltage drop. This feature enhances system reliability and prevents premature reset deactivation.
• Surface Mount Technology: The MAX809S is designed for surface-mount applications, offering a compact and reliable solution for modern PCB designs. This mounting type is ideal for high-density boards and automated manufacturing processes.
• Compliance and Standards: The MAX809S meets various industry standards, including REACH unaffected and RoHS3 compliance. It is also classified under ECCN EAR99 and HTSUS 8542.39.0001, ensuring its suitability for a wide range of applications.
• Moisture Sensitivity Level: The device has a moisture sensitivity level (MSL) of 1, which means it is not affected by moisture and can be stored and handled without special precautions.

MAX809S Applications

The MAX809S is well-suited for a variety of applications where reliable voltage monitoring and system reset functionality are critical. Some specific use cases include:

• Power Supply Monitoring: In power supply units, the MAX809S ensures that the output voltage remains stable and within the specified range. This prevents damage to sensitive components and maintains system performance.
