Battery Chargers Procurement Notes

Verify component authenticity through authorized channels as the part status is obsolete. Confirm package integrity and pin alignment for the 28-TQFN form factor. Ensure design compatibility with SMBus Level 2 protocols and validate thermal performance within the specified operating temperature range before integration.

Battery Chargers Selection Notes

Select this component for applications requiring precise lithium-ion charging control via SMBus. Consider the 8A current capability and 1-4 cell support when sizing for specific battery architectures. Evaluate the 22V supply limit and 28-TQFN footprint against board space constraints and system voltage requirements.

Battery Chargers Part Context

This model belongs to the ISL8873x family of battery chargers from Renesas. It shares architectural similarities with the ISL88731 and ISL88732 but distinguishes itself through SMBus Level 2 compliance and integrated boost mode capabilities. The family targets high-performance portable and industrial charging solutions.

Battery Chargers Replacement Considerations

Public confirmed substitute part numbers are not available for this obsolete component. Designers should evaluate newer Renesas PMIC families or consult manufacturer documentation for recommended upgrades.
