BU46L274G-TL

BU46L274G-TL Description

The BU46L274G-TL is a single-channel voltage detector IC designed by ROHM Semiconductor, a leading manufacturer in the electronics industry. This device is part of the BU46Lxxx series, known for its reliability and precision in power management applications. The BU46L274G-TL is designed to monitor a single voltage supply and ensure it remains within specified operational limits, making it an essential component for maintaining system stability and preventing malfunctions due to voltage fluctuations.

BU46L274G-TL Features

• Voltage Monitoring: The BU46L274G-TL is designed to monitor a single voltage supply with a threshold voltage of 2.7V. This feature ensures that the device can accurately detect and respond to voltage levels, providing reliable protection against under-voltage conditions.
• Reset Functionality: The reset function of the BU46L274G-TL is active low, meaning it will assert a reset signal when the monitored voltage drops below the threshold. This active-low reset is crucial for applications requiring a clear and immediate response to voltage drops.
• Reset Timeout: The device features a minimum reset timeout of 240ms, ensuring that the reset signal is held long enough to allow the system to stabilize and recover properly.
• Mounting Type: The BU46L274G-TL is designed for surface-mount applications, making it suitable for compact and high-density PCB designs. This mounting type allows for efficient use of space and enhances the overall reliability of the device.
• Package Type: The device is packaged in a tape and reel format (Tape & Reel - TR), which is ideal for automated assembly processes and ensures consistent and reliable handling during manufacturing.
• Moisture Sensitivity Level: The BU46L274G-TL has a moisture sensitivity level (MSL) of 3, which means it can be safely stored for up to 168 hours in a controlled environment before assembly. This feature is crucial for maintaining the integrity of the device during the manufacturing process.
• Compliance: The BU46L274G-TL is REACH unaffected and ROHS3 compliant, ensuring it meets the highest environmental and safety standards. This compliance is essential for manufacturers aiming to produce eco-friendly and sustainable products.
• Obsolete Status: While the BU46L274G-TL is currently marked as obsolete, it remains a viable option for legacy systems and applications where its specific features and performance characteristics are still required.
