Power Management - Specialized Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before procurement. Confirm that the specific suffix -E2 aligns with required RoHS compliance standards. Ensure compatibility with existing Qi transmitter reference designs, such as the BD57020MWV-EVK-002, when integrating this IC into new hardware architectures.

Power Management - Specialized Selection Notes

Select this IC for applications requiring a dedicated Qi wireless power transmitter solution. It is suitable for systems needing integrated coil drive inversion and communication control. Consider its limited output current of 30 mA and fixed 3.3 V output when designing power delivery stages for compatible receivers.

Power Management - Specialized Part Context

This component belongs to the BD570xx series of Qi/PMA wireless power ICs manufactured by ROHM Semiconductor. While the broader family includes receiver ICs like the BD57015GWL, the BD57020MWV-E2 specifically functions as a transmitter unit designed to work in tandem with compatible receivers for wireless power transfer.
