Procurement Notes

Verify the obsolete status and last-time-buy availability before procurement planning. Confirm that the SSOP-3 package dimensions match your PCB footprint requirements. Ensure compatibility with the 4.3V detection threshold for your specific circuit design. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a fixed 4.3V detection threshold is required. Consider the SSOP-3 package size constraints for your layout. Evaluate the open-drain output capability against your downstream logic input requirements. Verify that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the BD48xxx series of voltage detectors from ROHM Semiconductor. The series offers various detection voltages in 0.1V increments, allowing for flexible design options. These ICs are characterized by high precision and low power consumption, making them suitable for modern low-power electronics.
