Procurement Notes
Verify the specific suffix ES1R against the manufacturer's official datasheet to confirm pinout and functional specifications. Ensure compatibility with your system's thermal design requirements given the integrated NTC feature. Confirm package type matches your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a cost-effective linear solution is required for single-cell lithium batteries. It is suitable for designs where space efficiency is prioritized over high-current fast charging capabilities. Consider the integrated NTC functionality if thermal management without external sensors is desired.
Part Context
This part belongs to the TPB4056B series of linear battery chargers manufactured by 3PEAK. The series focuses on providing high-integration solutions for portable electronics. The TPB4056B2X-ES1R variant specifically includes NTC monitoring capabilities within an 8-ESOP package, distinguishing it from basic variants in the same family.
Replacement Considerations
