Procurement Notes
Verify the specific suffix and package variant when ordering, as manufacturer part numbers may include additional codes for tape/reel or cut tape configurations. Confirm the operating temperature range and interface compatibility with your system design before procurement. Ensure that the supplier provides genuine components from authorized channels to guarantee performance reliability and adherence to RoHS standards.
Selection Notes
Select this component for applications requiring a compact solution for single-cell Li-Ion or Li-Polymer batteries. The 2A charging capability suits moderate-power portable devices. Consider the 40-WQFN footprint for PCB layout constraints. Verify that the host controller can support the required I²C communication protocol for configuration and status monitoring during operation.
Part Context
This part belongs to Richtek's portfolio of power management integrated circuits (PMICs) designed for battery charging applications.
