BD49L38G-TL

BD49L38G-TL Description

The BD49L38G-TL is a single-channel voltage detector IC designed by Rohm Semiconductor, a leading manufacturer in the power management sector. This device is part of the BD49Lxx series and is specifically tailored for applications requiring precise voltage monitoring. It features a threshold voltage of 3.8V, ensuring reliable detection and response to voltage levels. The BD49L38G-TL is housed in a 3SSOP package and is available in a Tape & Reel (TR) format, facilitating efficient surface mount assembly processes.

BD49L38G-TL Features

• Voltage Monitoring: The BD49L38G-TL is designed to monitor a single voltage level with a precise threshold of 3.8V. This feature is crucial for systems where maintaining a specific voltage level is essential for stable operation.
• Active Low Reset: The reset function of the BD49L38G-TL is active low, which means it asserts a reset signal when the monitored voltage drops below the threshold. This mechanism ensures that connected systems can safely reboot or enter a safe state when voltage levels are insufficient.
• Surface Mount Compatibility: The BD49L38G-TL is designed for surface mount technology (SMT), making it ideal for modern PCB designs that require compact and reliable components. The 3SSOP package is robust and suitable for automated assembly processes.
• Moisture Sensitivity Level (MSL) 3: With an MSL rating of 3, the BD49L38G-TL can withstand up to 168 hours of exposure to moisture, ensuring reliability in various environmental conditions.
• Compliance and Standards: The BD49L38G-TL is REACH unaffected and RoHS3 compliant, adhering to stringent environmental and safety regulations. This compliance ensures that the component is suitable for use in a wide range of applications without compromising on environmental standards.

BD49L38G-TL Applications

The BD49L38G-TL is ideal for applications requiring precise voltage monitoring and reliable reset functionality. Key use cases include:

• Power Supply Monitoring: In power supply units, the BD49L38G-TL can monitor the output voltage to ensure it remains within the specified range. If the voltage drops below 3.8V, the device can trigger a reset, preventing potential damage to connected components.
• Embedded Systems: For embedded systems, such as microcontrollers and IoT devices, the BD49L38G-TL can provide a reliable reset mechanism in case of voltage fluctuations. This ensures that the system can recover gracefully from power-related issues.
