BD5347G-TR

BD5347G-TR Description

The BD5347G-TR is a high-performance, single-channel voltage supervisor IC designed by ROHM Semiconductor. This device is part of the BD53xx series and is specifically engineered to monitor a single voltage source with a threshold voltage of 4.7V. It is packaged in a 5SSOP format and is available in tape and reel (TR) form, making it suitable for automated surface-mount assembly processes. The BD5347G-TR is designed to ensure reliable operation in various electronic systems by providing accurate voltage monitoring and reset functionality.

BD5347G-TR Features

• Voltage Monitoring: The BD5347G-TR is designed to monitor a single voltage source with a precise threshold voltage of 4.7V. This feature ensures that the device can accurately detect voltage levels and trigger appropriate actions when the monitored voltage falls below the specified threshold.
• Active Low Reset: The reset function of the BD5347G-TR is active low, which means that the reset signal is asserted when the monitored voltage drops below the threshold. This design choice is beneficial for applications where a low reset signal is required to reset the system.
• Surface Mount Technology: The BD5347G-TR is designed for surface-mount assembly, which allows for efficient and reliable integration into modern electronic circuits. The 5SSOP package format ensures that the device can be easily mounted on printed circuit boards (PCBs) using standard surface-mount equipment.
• Moisture Sensitivity Level (MSL): The BD5347G-TR has an MSL rating of 1 (Unlimited), which indicates that the device is not sensitive to moisture. This feature is particularly important for applications where the device may be exposed to humid environments.
• Compliance and Standards: The BD5347G-TR is REACH unaffected and ROHS3 compliant, ensuring that it meets the highest environmental and safety standards. The ECCN classification of EAR99 further confirms its compliance with international export regulations.
• Programmability: Although the BD5347G-TR is not verified for DigiKey programmability, it offers a reliable and fixed configuration that is suitable for a wide range of applications.

BD5347G-TR Applications

The BD5347G-TR is ideal for a variety of applications where reliable voltage monitoring and reset functionality are required. Some specific use cases include:

• Power Supply Monitoring: In power supply units (PSUs), the BD5347G-TR can be used to monitor the output voltage and ensure that it remains within the specified range. If the voltage drops below the threshold, the device can trigger a reset to prevent damage to connected components.
• Embedded Systems: In embedded systems, such as microcontrollers and microprocessors, the BD5347G-TR can be used to monitor the supply voltage and provide a reset signal if the voltage falls below the safe operating range. This helps to prevent system crashes and ensures reliable operation.
• Industrial Control Systems: In industrial control systems, the BD5347G-TR can be used to monitor critical power supplies and ensure that they remain within the specified voltage range. This helps to prevent equipment damage and ensures the reliability of the control system.
• Telecommunications Equipment: In telecommunications equipment, the BD5347G-TR can be used to monitor the power supply voltage and provide a reset signal if the voltage drops below the threshold. This helps to prevent communication disruptions and ensures the reliability of the equipment.
