• DSP voltage detection

Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt, as this component may be subject to end-of-life status or last-time buy conditions. Confirm RoHS compliance documentation matches the required environmental standards for your assembly process. Ensure the SSOP-5 package dimensions align with your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3 V detection threshold is required for single-channel voltage monitoring. The open-drain output allows for flexible interfacing with various logic levels through external pull-up resistors. Consider the 50 ms reset delay time to ensure adequate stabilization periods for downstream circuits during power-up sequences.

Part Context

This part belongs to the BD45 series of voltage detectors designed for processor supervision. The series emphasizes high precision and low power consumption, suitable for portable and industrial electronics. The BD45335G-TR specifically targets applications requiring reliable reset generation at standard 3.3 V logic levels.

Replacement Considerations

BD5233G-1TR is listed as a recommended replacement with the same SSOP-5 package. Note that the replacement offers adjustable delay timing compared to the fixed delay of the original part.
