Procurement Notes
Verify the specific suffix 'S' against official datasheets to confirm the 60V rating variant. Ensure compatibility with I2C bus levels and check for moisture sensitivity classification requirements during storage and handling. Confirm package marking 'B25758S' matches procurement specifications.
Selection Notes
Select this component when a bidirectional buck-boost controller with integrated driver capability is required. Consider the 60V input limit and VQFN-36 thermal performance. Verify I2C addressability and switching frequency adjustability against system timing constraints.
Part Context
Part of the BQ25758 family of power management ICs designed for battery management applications. The SRRVR suffix indicates a reel-packaged version of the BQ25758S variant, distinguished by its specific voltage rating and pin configuration compared to other family members.
Replacement Considerations
Consult official substitution lists for equivalent bidirectional controllers. Verify pin-to-pin compatibility and electrical parameter alignment before replacing.
