Battery Management Procurement Notes

Verify the specific suffix (V160) against the latest manufacturer documentation to ensure compatibility with required firmware or hardware revisions. Confirm that the 38-TSSOP package aligns with the target PCB footprint. Check for any recent product change notices or end-of-life announcements, as availability may be limited. Ensure the design-in process accounts for the humidity sensitivity level specified in the datasheet.

Battery Management Selection Notes

Select this component when an SMBus interface is required for system communication and high accuracy is needed for state-of-charge reporting. The Impedance Track algorithm necessitates proper calibration during the initial design phase. Consider the thermal operating range of -40°C to +85°C to ensure reliability in the intended environment. Verify that the battery cell count and chemistry are supported by the V160 configuration.
