Procurement Notes
Verify the specific revision code and packaging details against the official ROHM datasheet before ordering. Confirm that the 5-SSOP package matches your PCB footprint requirements. Ensure the 3.1V threshold aligns with your system's voltage monitoring needs. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a precise 3.1V threshold is required for voltage supervision. The low 850 nA operating current makes it suitable for battery-powered devices. The open drain output allows for flexible interfacing with various logic levels. Manual reset capability adds control over the reset state during debugging or initialization.
Part Context
This part belongs to the BD45XXXG series of high-accuracy voltage detectors. These ICs are designed for low power consumption and reliable performance in portable electronics. The series offers various threshold voltages to suit different application requirements while maintaining a compact form factor.
Replacement Considerations
Check for direct pin-compatible substitutes within the BD45 series with similar threshold voltages. Verify that any replacement maintains the same open drain output configuration and manual reset feature. Ensure the alternative part supports the required 950 mV minimum supply voltage.
